What is the best gem for an engagement ring?

When considering the perfect gem for an engagement ring, a myriad of factors come into play, including durability, color, rarity, and, of course, personal preference. Traditionally, diamonds have been the go-to choice for engagement rings, symbolizing eternal love with their unmatched hardness and brilliant sparkle. However, modern trends have seen a shift towards more unique and personalized options, including other gemstones that offer a range of colors, textures, and meanings. This article explores the qualities of various gems to help you decide which might be the best choice for an engagement ring.

Diamonds: The Timeless Choice

Diamonds are renowned for their unparalleled hardness and durability, scoring a perfect 10 on the Mohs scale of mineral hardness. This makes them an ideal choice for an engagement ring that is worn daily. The traditional appeal of diamonds lies in their symbolization of eternal and unbreakable love. They offer exceptional brilliance and fire, with the ability to reflect and refract light in a way that no other gem can. While white diamonds are the most popular, colored diamonds, such as pink, yellow, and blue, offer a unique twist on the classic stone.

Sapphires: A Symbol of Loyalty

Sapphires, scoring a 9 on the Mohs scale, are second only to diamonds in terms of durability, making them another excellent choice for engagement rings. Traditionally a symbol of nobility, truth, and sincerity, sapphires have been cherished throughout history. Although blue is the most well-known color, sapphires come in a rainbow of hues, including pink, yellow, and green. Their rich color and hardness make them a practical and beautiful choice for an engagement ring.

Rubies: The Gem of Passion

Rubies, with their deep red color, are often associated with passion, protection, and prosperity. Like sapphires, rubies score a 9 on the Mohs scale, making them a durable choice for everyday wear. Rubies can command the highest per-carat price of any colored stone, making them a luxurious and prestigious choice for an engagement ring. The intensity of their color is the most important factor in determining a ruby's value, with the most sought-after shade being a deep, vivid red.

Emeralds: The Stone of Rebirth

Emeralds are known for their lush green color, which can range from a light to a deep, rich green. Associated with fertility, rebirth, and love, emeralds have a unique charm. They are softer than diamonds, sapphires, and rubies, scoring between 7.5 and 8 on the Mohs scale, which means they require more care to avoid scratches and chips. However, their unique color and historical significance make them a desirable choice for those seeking a ring with character and heritage.

Moissanite: A Diamond Alternative

Moissanite is a gemstone born from the stars, first discovered in a meteor crater. It is nearly as hard as a diamond, scoring 9.25 on the Mohs scale, and offers a brilliance and fire that can even exceed that of diamonds. Moissanite is a popular choice for those looking for the durability and sparkle of a diamond at a more affordable price point. It is also valued for its ethical and sustainable qualities, as most moissanite on the market is lab-created.

Choosing the Right Gem

When choosing the best gem for an engagement ring, consider the lifestyle and preferences of the wearer. For those with active lifestyles or who work with their hands, a harder gem like a diamond or sapphire may be the best choice. For those seeking a unique or colorful option, consider rubies, emeralds, or even lesser-known gems like aquamarine or opal, keeping in mind their care requirements.

The budget also plays a significant role in the choice of gemstone. While diamonds are traditionally the most expensive option, choosing a less common gemstone or a lab-created stone like moissanite can offer savings without compromising on beauty or durability.

Aquamarine: The Serene Beauty

Aquamarine, with its tranquil sea-blue hues, embodies calmness, clarity, and harmony. Scoring between 7.5 and 8 on the Mohs scale, aquamarines are durable enough for daily wear with proper care. This gem is often associated with the soothing qualities of the ocean, making it a perfect choice for couples seeking a symbol of tranquility and eternal youth in their relationship.

Opal: The Play of Color

Opals are celebrated for their dazzling play-of-color, with internal colors that shimmer and shift as the stone moves in the light. Each opal is unique, featuring a one-of-a-kind pattern of rainbow hues. With a Mohs hardness rating of 5.5 to 6.5, opals are softer and require more careful handling. They symbolize hope, creativity, and protection, offering a distinct choice for those who value individuality and emotional expression.

Morganite: The Heart Stone

Morganite, with its warm, peachy-pink tones, exudes love and compassion. It's a beryl gemstone, like emerald, and has a hardness of 7.5 to 8 on the Mohs scale. Morganite is believed to attract love and maintain it, making it an ideal symbol for an engagement ring. Its gentle hue offers a romantic and contemporary alternative to traditional gemstones.

Garnet: The Gem of Commitment

Garnets are often associated with deep red colors, but they can actually come in a variety of hues, including green, orange, and purple. With a Mohs hardness of 6.5 to 7.5, garnets symbolize passion, loyalty, and devotion. Their rich colors and affordability make garnets an appealing choice for couples seeking a balance between uniqueness and tradition.

Tourmaline: The Rainbow Stone

Tourmaline is known for its wide range of colors, from vibrant greens and pinks to intriguing multicolored stones. With a Mohs hardness of 7 to 7.5, tourmaline is suitable for everyday wear with some care. It is often associated with artistic inspiration and healing, making it a meaningful choice for creative souls and those looking for a gem that represents personal growth and healing.

Amethyst: The Calming Stone

Amethyst, with its striking violet hues, offers a sense of calm, spirituality, and protection. Scoring a 7 on the Mohs scale, it's relatively durable but should be protected from hard knocks and extreme temperature changes. Amethyst's serene color and affordability make it a popular choice for those seeking a spiritual or calming influence in their relationship.

Peridot: The Sun Gem

Peridot is known for its vibrant, olive-green color that's especially striking under natural sunlight. With a hardness of 6.5 to 7 on the Mohs scale, peridot symbolizes strength and vitality. It's said to bring good luck, peace, and success, making it an optimistic choice for an engagement ring.

Choosing Among the Lesser-Known Gems

When selecting one of these lesser-known gems for an engagement ring, consider the stone's hardness and care requirements, especially if the ring will be worn daily. Also, think about the symbolic meanings of each gemstone and how they align with your relationship and values. While diamonds and other traditional stones like sapphires and rubies have their place, exploring alternative gemstones can lead to a more personalized and meaningful engagement ring that truly represents your unique bond.


The best gem for an engagement ring is a highly personal choice, influenced by factors such as durability, color preference, symbolism, and budget. While diamonds remain the traditional choice, other gemstones like sapphires, rubies, emeralds, and moissanite offer unique and meaningful alternatives. Ultimately, the best choice is one that resonates with the personal style and values of the wearer, symbolizing their unique love story.
