In the book Goldsmithing & Silver Work: Jewelry, Vessels & Ornaments by Carles Codina, the author discusses the differences between moissanite and diamond. 

Moissanite is a gemstone that is often referred to as a “synthetic diamond” because it has a very similar chemical composition and physical properties to diamond. However, moissanite is actually a naturally occurring mineral that was first discovered in 1893 in a meteorite that crashed in Siberia. 

Diamond is a well-known gemstone that is prized for its beauty and durability. It is the hardest natural substance on Earth, and it is also very rare. This makes diamonds very valuable. 

Moissanite is less expensive than diamond, and it is available in a wider range of colors. Moissanite is also just as durable as diamond, but it is slightly less scratch-resistant. 

Physical Properties 

Moissanite and diamond have very similar physical properties. They are both very hard, and they both have a high refractive index. This means that they both sparkle and shine very brightly. 

However, there are some small differences between the two gemstones. Moissanite has a slightly higher refractive index than diamond, which means that it appears slightly more brilliant. Moissanite is also slightly less dense than diamond, which means that it is slightly lighter. 


Moissanite is available in a wider range of colors than diamond. Moissanite can be colorless, near colorless, yellow, brown, or even blue. Diamond, on the other hand, is typically colorless. 


Moissanite is much less expensive than diamond. This is because moissanite is more abundant than diamond, and it is also easier to produce. 


Moissanite is just as durable as diamond. Both gemstones are very hard, and they can withstand a lot of wear and tear. However, moissanite is slightly less scratch-resistant than diamond. 


Moissanite and diamond are both beautiful and durable gemstones. However, there are some key differences between the two gemstones. Moissanite is less expensive, and it is available in a wider range of colors. Diamond, on the other hand, is more rare and more valuable. 

The best choice for you will depend on your individual needs and preferences. If you are looking for a beautiful and affordable gemstone, moissanite is a great option. If you are looking for a rare and valuable gemstone, diamond is the better choice.
