Types of Stones for Engagement Rings

Engagement rings hold great significance as a representation of love and devotion, often imbued with profound personal significance for both individuals in the relationship.

Choosing the perfect stone for an engagement ring is an important decision, as it can represent the unique bond shared between two people.

While diamonds are the classic choice for these special pieces of jewelry, there are many other beautiful gemstones to consider that can add a unique and personal touch to the ring.

In recent years, there has been a surge of interest in alternative and unconventional gemstones for engagement rings.

These stones offer a way for couples to express their individuality and can be more budget-friendly than traditional diamonds.

The choices available range from precious gems like sapphires, emeralds, and rubies to less common but equally stunning options such as tanzanite, morganite, and tourmaline.

The metal setting of the ring also plays an important role in creating the perfect overall appearance for the chosen stone.

Key Takeaways

  • Choosing the right stone for an engagement ring is crucial, with various beautiful options beyond the classic diamond.
  • Alternative and unconventional gemstones can express individuality and offer budget-friendly options.
  • The metal setting of the ring also plays a role in creating the perfect appearance for the chosen stone.

The Importance of Engagement Ring Stones

What stone is used in engagement ring?

Engagement rings are a symbol of love, commitment, and the start of a lifelong journey together.

The stone chosen for an engagement ring plays a crucial role in reflecting the value of this special occasion.

This is why selecting the right gemstone is an essential part of the engagement ring process.

While the round, white diamond is the most popular choice for engagement rings, various stunning alternatives can also suit the preferences and budgets of couples.

Some of these alternative stones include moissanite, sapphires, rubies, morganite, alexandrite, and emeralds.

When choosing a stone for an engagement ring, it is important to consider factors such as durability, appearance, and cost.

Durability is a significant consideration when selecting an engagement ring stone. It is essential that the stone is robust and capable of withstanding everyday wear.

Stones with a rating of seven to ten on the hardness scale, such as diamonds, moissanite, and certain gemstones, are suitable for engagement rings.

This ensures that the ring lasts a lifetime, symbolizing the perpetuity of a couple’s love and commitment.

Appearance is another vital factor to consider when choosing a stone for an engagement ring. A stone should not only be eye-catching but also reflect the couple’s unique taste and style.

Colored stones, such as sapphires, rubies, and emeralds, offer an unconventional and visually intriguing alternative to traditional diamonds.

Rare engagement ring stones, like tanzanite, can add an exclusive and extraordinary touch to the ring.

Cost plays a significant role in the decision-making process. Diamonds are often associated with a higher price tag, but there are many alternative gemstones available at more budget-friendly prices.

For example, gemstones like moissanite and morganite offer a similar sparkle and durability to diamonds but at a more affordable cost.

This allows couples to invest in other aspects of their wedding or future life together while still purchasing a beautiful and meaningful engagement ring.

Diamonds: The Classic Choice

Diamonds are the quintessential engagement ring stone and have been used in this context for centuries.

They are highly regarded for their brilliance, durability, and the way they reflect light.

When it comes to durability, diamonds are the hardest natural material found on Earth, making them an excellent choice for everyday wear.

Diamond Shapes and Cuts

Diamonds come in a variety of shapes and cuts that accentuate their beauty and maximize their ability to refract light. Some popular diamond shapes include:

  • Round: The most popular and classic shape, featuring 58 facets that maximize light reflection.
  • Princess: A square shape with pointed corners, offering a contemporary and geometric look.
  • Cushion: A square shape with rounded corners, resembling a pillow.
  • Emerald: A rectangular shape with step-cut facets and clean, angled lines.
  • Asscher: A square shape with step-cut facets and similar to the emerald cut, but with a more geometric appearance.
  • Oval: An elongated shape that offers a larger surface area and a slimming effect on the wearer’s finger.
  • Marquise: An elongated shape with pointed ends, designed to maximize carat weight.

Colors and Clarity

While diamonds are commonly thought of as colorless stones, they actually come in a range of colors. These can include:

  • Colorless (D-F): The rarest and most valuable, these diamonds allow the most light to pass through and display exceptional brilliance.
  • Near colorless (G-J): These diamonds have minimal color but still maintain their brilliance, offering a more budget-friendly option.
  • Faint color (K-M): Slightly tinted, these diamonds may have a warm hue, typically yellow or gray, which can be noticeable in larger sizes.

In addition to color, a diamond’s clarity is also an important factor to consider.

Clarity refers to the visual appearance of the inclusions (internal imperfections) and blemishes (external imperfections) within the diamond. The scale ranges from flawless (FL) to included (I3).

Engagement rings featuring diamonds are often set in white gold or platinum, as these metals complement the stone’s brilliance and highlight the best attributes of the gemstone.


Sapphires are a popular choice for engagement rings due to their durability and versatility.

They rank a 9 on the Mohs scale of hardness, making them one of the most scratch-resistant gemstones available.

Sapphires also come in a variety of colors, such as blue, pink, yellow, and even rare color-changing variations.

They have the added benefit of being more budget-friendly compared to diamonds.


  • Durable and scratch-resistant
  • Available in multiple colors
  • More affordable than diamonds


  • May not be as colorless or brilliant as diamond


Rubies are another popular gemstone choice for engagement rings, with a deep red color symbolizing love and passion.

Rubies also rank 9 on the Mohs scale, demonstrating great durability. Additionally, the rarity of high-quality rubies adds to their value and allure.

However, rubies tend to be more expensive than sapphires due to limited availability and demand.


  • Durable and scratch-resistant
  • Symbolic color for love and passion
  • Rare and valuable


  • More expensive than sapphires
  • Limited color options


Emeralds are a classic and elegant choice when it comes to engagement ring gemstones. Known for their lush green color, emeralds bring a unique and vibrant touch to jewelry.

Despite their beauty, emeralds rank lower on the Mohs scale (7.5-8), making them somewhat more susceptible to scratches compared to sapphires and rubies.

Also, emeralds often have natural imperfections called inclusions, which can make them more fragile.


  • Unique and vibrant green color
  • Classic and elegant style


  • More prone to scratching and damage
  • Often includes natural imperfections

Alternative Gemstones

Can an engagement ring be any stone?


Morganite is a pink to peach-colored gemstone that belongs to the beryl family. It is admired for its delicate hue, which symbolizes love and romance.

As a relatively strong gemstone, with a Mohs hardness of 7.5 to 8, morganite is suitable for everyday wear.


Moissanite, a diamond alternative, is known for its exceptional durability and brilliance. With a high refractive index, this gemstone closely resembles the fire and sparkle of a diamond.

Moissanite has a Mohs hardness of 9.25, making it an excellent choice for engagement rings.


Aquamarine, also a member of the beryl family, displays a beautiful range of blue tones, representing tranquility and harmony.

Its hardness ranges from 7.5 to 8 on the Mohs scale, making it a suitable choice for daily wear. Aquamarines are often set in white gold or platinum to enhance their cool hues.


Tanzanite, a rare gemstone, exhibits a mesmerizing blend of blue and violet hues. With a Mohs hardness of 6 to 7, tanzanite is slightly less durable than its counterparts.

Nonetheless, its unique beauty and captivating color make it a popular choice for engagement rings.


Amethyst, known for its rich purple color, symbolizes passion and desire. This durable gemstone, with a Mohs hardness of 7, is often found in intricate designs and settings.

Amethyst’s affordability and eye-catching hue make it an attractive choice for alternative engagement rings.


Garnet offers a wide variety of colors and is associated with loyalty and devotion. With a hardness of 6.5 to 7.5 on the Mohs scale, garnet is relatively durable and suitable for everyday wear.

Its diverse range of colors allows for unique and personal engagement ring designs.


Pearls, often associated with innocence and purity, can add a touch of elegance and sophistication to an engagement ring.

However, it is essential to consider that pearls are relatively soft, with a Mohs hardness of only 2.5 to 4.5. They require extra care and may not be the best choice for those with active lifestyles.

Unconventional Gemstones

When looking for an engagement ring stone that deviates from the traditional diamond, there are several gemstones that offer a stunning and unique alternative.

In this section, we will discuss five unconventional gemstones for engagement rings: Opal, Sun and Moonstone, Lapis Lazuli, Turquoise, and Spinel.


Opal, known for its mesmerizing play of colors, is a captivating choice for an engagement ring stone.

Ranging from milky white to black and showcasing a kaleidoscope of colors, opal is ideal for those seeking a distinctive piece.

However, it’s essential to note that opal has a relatively low hardness of 5.5-6.5 on the Mohs scale, meaning it can be more prone to scratches and damage.

To protect the opal in your engagement ring, consider a protective setting, such as a bezel.

Sun and Moonstone

Sunstone and moonstone are both part of the feldspar group, yet they possess unique characteristics that make them desirable for engagement rings.

Sunstone emanates a warm, glittering effect resembling the sun’s rays, while moonstone displays a soft, bluish adularescence, giving it a mysterious allure.


  • Colors: Orange, red, brown, green, and clear
  • Mohs scale hardness: 6-6.5


  • Colors: Colorless, white, gray, green, peach, and brown
  • Mohs scale hardness: 6-6.5

Both sunstone and moonstone are relatively soft stones, so it’s advised to choose a setting that offers protection, such as bezel or halo.

Lapis Lazuli

What color of ring is best for engagement?

Regarded as a symbol of wisdom and truth, lapis lazuli is a deep blue stone with golden flecks of pyrite, making it an alluring engagement ring option.

Lapis lazuli has a Mohs scale hardness of 5-5.5, so it’s crucial to take extra precautions to keep the stone safe from damage.

Opt for a protective setting and avoid direct exposure to harsh chemicals or extreme temperature fluctuations to ensure the longevity of your lapis lazuli engagement ring.


Turquoise, a vibrant blue-green stone, has been cherished for centuries for its unique hue and natural patterns.

For couples seeking a bold and unconventional engagement ring, turquoise offers a striking option.

With a Mohs scale hardness of 5-6, turquoise requires proper care and a protective setting, such as a bezel, to preserve its beauty.


Spinel, a lesser-known but equally captivating gemstone, is available in a variety of colors, including red, pink, blue, violet, and black.

Its durability, with a Mohs scale hardness of 8, makes it a suitable choice for engagement rings.

Due to its rarity, spinel can be a more affordable option while still providing a visually stunning and unique engagement ring stone.

Metals for Engagement Ring Settings

When selecting an engagement ring, it’s essential to consider the various metal options for the ring’s setting.

In this section, we will discuss the four popular metals: Yellow Gold, White Gold, Rose Gold, and Platinum.

Yellow Gold

Yellow Gold is a classic and timeless choice for engagement rings. It is made from a mixture of pure gold and alloys such as copper and zinc to increase its strength.

Yellow gold is available in different karats, with 18K gold containing 75% gold and 14K gold containing 58.5% gold.

Its warm tones complement many skin tones, making it a popular choice for traditional and vintage ring designs.

White Gold

White Gold is another popular metal for engagement ring settings due to its stylish and elegant appearance.

This metal is created by combining pure gold with other white metals like palladium or nickel and coated with rhodium for a durable, silver-toned finish.

White gold is available in 14K and 18K options, with 14K gold containing 58.5% gold and 18K gold containing 75% gold.

The rhodium plating may need periodic re-application to maintain its shine and luster.

Rose Gold

Rose Gold has gained popularity in recent years for its unique and romantic appearance.

This metal is crafted by combining pure gold with a higher percentage of copper to give it the distinct blush pink hue.

Like yellow and white gold, rose gold is also available in 18K and 14K options, depending on the desired gold content.

Rose gold’s warm tones work well with various skin tones and offer a modern twist on classic engagement ring designs.


Platinum is a durable and luxurious metal, making it a sought-after choice for engagement ring settings.

It is a naturally white metal that maintains its shine without needing re-coating, unlike white gold. Platinum is less malleable than gold, making it stronger and more resistant to scratches and wear.

However, it is also more expensive due to its density and rarity. This metal is an excellent choice for those seeking a long-lasting and premium ring setting.

Choosing the Perfect Ring Style

The perfect ring style should not only be beautiful but also reflect the wearer’s personality and aesthetic preferences.

One of the timeless ring styles is the solitaire. Known for its classic elegance, a solitaire engagement ring features a single gemstone, traditionally a round white diamond, mounted on a simple band with a prong or claw setting.

This allows the stone’s beauty to shine without distraction.

Another popular style is the halo engagement ring, which has a dazzling center gemstone surrounded by a circle of smaller diamonds.

This setting accentuates the main stone, often making it appear larger and more brilliant.

There are also numerous shapes to consider when selecting the perfect stone.

While round diamonds remain the most popular shape, other options include oval, pear, cushion, emerald, marquise, and princess cuts.

Each shape can provide a unique and distinctive look, so it’s essential to explore what suits the wearer’s style best.

In addition to the classic diamond engagement ring, there is a growing trend of choosing alternative gemstones.

Popular engagement ring stones such as sapphires, rubies, emeralds, and moissanite offer a striking visual appeal and can cater to various aesthetics.

These gems allow couples to express their individuality and personal taste in their fine jewelry.

Finally, the choice of metal used for the band of the engagement ring can also significantly impact the overall design.

Platinum and gold are the most popular and expensive options, each providing a different look.

While platinum offers a modern, bright, and durable choice, gold comes in various colors, such as yellow, rose, and white, to suit an array of preferences.

Durability and Maintenance of Ring Stones

When choosing a stone for an engagement ring, it is crucial to consider its durability and maintenance requirements, since the ring will be worn daily.

Several factors contribute to a gemstone’s durability, including its hardness, resistance to scratching, and overall strength.

The most common measurement for gemstone hardness is the Mohs hardness scale.

Hardness, as defined scientifically, refers to the gemstone’s ability to resist scratching. Although it is an essential factor, hardness is only one aspect of a gemstone’s overall wearability grade.

Other factors like the stone’s setting, and its resistance to breakage and chipping, also contribute to its overall durability.

Diamonds, for example, rank highest on the Mohs hardness scale, with a hardness of 10.

This makes them an excellent choice for engagement rings due to their resistance to scratching and strength. However, diamonds can still chip or break if subjected to a strong impact at the right angle.

Sapphires and rubies are also popular choices for engagement ring stones, both ranking at a 9 on the Mohs hardness scale.

They offer good durability and require less maintenance than softer gemstones.

Emeralds, although beautiful and vibrant, have a hardness of 7.5-8, making them more prone to scratching and requiring more care in daily wear.

When it comes to maintenance, all engagement ring stones require periodic cleaning to maintain their beauty and sparkle.

A simple cleaning method involves soaking the ring in a bowl of warm water with a mild detergent, gently brushing the stone with a soft-bristled brush, rinsing with clean running water, and drying with a lint-free cloth or hair dryer.

Budget Considerations

How do you know a good engagement ring?

When selecting a stone for an engagement ring, it’s essential to consider your budget.

The traditional guideline of spending two months’ salary on a ring may not suit everyone’s financial situation.

Instead, focus on finding a beautiful and meaningful stone that aligns with your intended’s preferences and your financial constraints.

Alternative engagement ring stones are an excellent option for those looking to balance cost with quality.

Many stunning gemstones are available at a fraction of the price of a traditional diamond, without sacrificing beauty or durability.

Some popular budget-friendly alternatives include garnet, spinel, and rhodolite.

In addition to the cost of the stone, it’s crucial to account for the expenses associated with the entire wedding process, such as anniversaries, potential wedding bands, and other jewelry for the wedding day.

Prioritize your expenses and allocate your budget accordingly. Consider creating a spreadsheet to track and compare costs to ensure you stay within your limits.

It’s also helpful to research the hardness and durability of alternative engagement ring stones.

Some affordable gemstones may be more susceptible to damage, which could result in long-term expenses for repair or replacement.

Hardy stones such as garnet and spinel are excellent options, as they are both durable and cost-effective.
