Diamonds are said to be a girl’s best friend, but they are not for everyone. Some think the price point is too high, others question the ethicality of sourcing the stone, and some would prefer to go the non-traditional route. Oftentimes, we're asked what stones look like diamond?
There are no rules when it comes to choosing a gemstone for your engagement. If you don’t want diamonds but love the gemstone’s clear appearance, there are some excellent diamond-like stones you can choose as an alternative. They give just as much brilliance and come in stunning cuts.
In this article, we’ll take a look at some of the best diamond alternatives available.
What Are Diamond Replacements
Moissanite is the top choice for those who want a diamond look alike without compromising radiance and affordability. Moissanite's higher refractive index than diamond gives it a vibrant, rainbow-like brilliance at a more affordable price.
These faux diamonds are used in jewelry pieces for their similarities: They are just as clear as diamonds, and in some cases, such as moissanite, they shine even brighter. These qualities are why people choose them over gemstones such as sapphires, emeralds, and rubies.
Some diamond substitutes occur naturally, while others are synthetic. However, they are not just a substitute for the “real thing” as they come in designs, colors, and styles that are just as beautiful, which looks like diamonds, but cheaper.
Stones or Gems That Look Like Diamonds
Which gemstones compare to diamonds? Moissanite and white sapphire are among the most similar in appearance, but several other stones can also mimic a diamond’s brilliance at different price points and durability levels. While each has visible distinctions, these alternatives offer a diamond-like look that can suit a range of preferences and budgets.
1. Moissanite
These stones may be less expensive than diamonds, but they are hardly a step down in terms of quality. It has the most brilliance and fire of all popular gemstones, even more than diamonds: On the brilliance Refractive Index (RI), Moissanite ranges from 2.65 to 2.69, higher than diamond’s 2.42. It is also known as the world’s most brilliant gemstone with a dispersion of 0.104, which is 2.4 times the fire of a diamond.
Just like diamonds, jewelry made with moissanite is extremely durable. It is one of the hardest known elements on earth, making it extremely resistant to scratching, chipping, and breaking.
2. Lab-Grown Diamond
Lab-grown diamonds are the closest possible alternative because they are chemically, physically, and optically identical to natural diamonds. They offer the same brilliance, hardness of 10 on the Mohs scale, and long-term durability, but are typically more affordable. The only difference is their origin, as they are created in controlled environments rather than mined.
3. White Sapphire
Sapphires are the most popular diamond alternative, but few know that they come in colors other than cobalt. Made of corundum, the most diamond-like stone is white sapphire, which is pure with no metal oxides to give it color.
Sapphire is loved for its relative affordability and durability: It is rated 9 on the Mohs scale of hardness, making it one of the hardest diamond alternatives to exist. However, sapphires may appear cloudy or milky, and one should go for the highest quality “AAA” stone, which has better clarity and brilliance. They also tend to get dirty quickly and may require regular cleaning.
4. White Topaz
White topaz is a colorless and widely available mineral, making it one of the more affordable diamond alternatives. While it does not match a diamond’s brilliance, it has a soft, clean sparkle and a refractive index of 1.64.
With a hardness of 8 on the Mohs scale, it is reasonably durable but more prone to scratching over time. Regular cleaning and polishing help maintain its clarity and shine.
5. White Zircon
White zircon is a natural gemstone known for its high brilliance, strong dispersion, and diamond-like luster. It can closely resemble a diamond in terms of sparkle, often appearing bright and lively.
However, with a hardness of around 6.5 to 7.5, it is softer and more brittle than many alternatives, making it more susceptible to wear. It is also important not to confuse zircon with cubic zirconia, as zircon is a natural stone.
6. Cubic Zirconia
One of the most common diamond alternatives, cubic zirconia (CZ) is zirconium oxide in cubic form and is famous for its exceptional clarity and affordability. You might have seen this stone in everyday jewelry pieces like necklaces and bracelets. Unlike other stones, CZ is a diamond simulant, meaning it is created in a lab to resemble diamonds. It also occurs naturally, though it is extremely rare. Cubic Zirconia also has an impressive hardness, ranking 8 to 8.5 on the Mohs scale. This gives it a good scratch resistance as well. However, it is known to chip relatively easily.
Which Option is Best?
Ultimately, the stone you choose will depend on your jewelry piece, preferences, and budget. However, if you want a stone that is just as beautiful as a diamond—and more brilliant, moissanite is the way to go.
Apart from its incomparable beauty, its durability makes it an ideal center stone for an engagement ring or heirloom gift. A moissanite stone is so durable that, just like diamond saws, the ceramic version of synthetic moissanite is commonly used to cut and slice other materials. It is just as resistant to scratching, chipping, and breaking as a diamond.
Moissanite is also a conflict-free, environmentally responsible choice as most of it is lab-grown, which eliminates the controversial mining process used for diamonds. See more of why we love moissanite in our blog on Moissanite vs. Diamond.
