Moissanite
A Brilliant Alternative to Diamonds
Moissanite is a stunning, lab-created gemstone that has gained popularity as an alternative to diamonds. Originally discovered in a meteor crater in Arizona by Nobel Prize-winning chemist Henri Moissan in 1893, this rare mineral was later synthesized for use in fine jewelry. Unlike diamonds, moissanite is composed of silicon carbide, giving it unique optical properties and exceptional brilliance. Due to its high rarity in nature, all moissanite on the market today is lab-created.
The History and Evolution of Moissanite
In the late 1990s, Charles & Colvard patented the process for creating moissanite gemstones, making them the sole producer for many years. However, since the patent expired in 2015, Chinese manufacturers have emerged as major players in moissanite production, offering some of the highest quality stones at competitive prices. Despite its affordability, moissanite remains relatively unknown, especially in Europe. At Hardtwein, we believe in the beauty and value of moissanite and are committed to making it more widely recognized as a premium but affordable alternative to diamonds.
Grading Moissanite: The 4Cs Apply—Partly
Moissanite is evaluated based on similar criteria as diamonds: Cut, Color, Clarity, and Size (Carat).
1. Clarity
Most moissanites are VVS (Very Very Slightly Included) or higher in clarity because, unlike lab-grown diamonds, their rough material generally does not have inclusions.
2. Cut
A well-cut moissanite maximizes its brilliance and fire. We ensure our moissanites have excellent cut, polish, and symmetry to achieve optimal sparkle.
3. Color
Moissanites are available in colorless (D-F), near-colorless (G-H), and slightly tinted (I-J) shades.
Besides that, moissanites are also available in a wide array of beautiful colors like yellow, green, grey and blue.
4. Size (Carat)
Unlike diamonds, moissanites are not typically sold in carats because they weigh less than diamonds of the same size. Instead, they are measured in millimeters (mm). For example, a 9 x 7 mm oval moissanite is equivalent in appearance to a 2-carat diamond. For a detailed comparison, you can check out Charles & Colvard’s moissanite size table.
How Moissanites Compares to Diamonds
Moissanite is not a fake diamond—it’s a gemstone in its own right with distinct properties. It exhibits more fire (rainbow-like flashes) than diamonds, has excellent durability, and is significantly more affordable. Diamonds on the other hand show more crispness and depth. With recent declining lab diamond prices, moissanite is now primarily appealing for larger stones (1ct and above) or jewelry with multiple stones, like our Elena Eternity Ring, where the cost savings are more noticeable.

Fake Moissanite Certification?
Chinese manufacturers often include GRA (Global Gemological Research Association) certificates with their moissanites. It’s important to note that GRA is not a real institution. Unlike diamonds, which have grading labs like GIA, IGI and HRD, moissanites have no officially recognized grading authority.
The certificates are not necessarily “fake,” nor do they mean that the stone is fake. They are typically issued by the moissanite manufacturers themselves and list the stone’s properties. However, since GRA is not a recognized institution and its certificates often contain spelling mistakes, fake addresses, and links to suspicious websites, we have chosen not to include them with purchases.
Instead, we test all our moissanites ourselves in-house to ensure authenticity and only work with the highest-quality manufacturers and cutters. Rest assured that the moissanite you receive from Hardtwein is of the best quality.
Moissanite Care & Maintenance
While moissanites are extremely durable, they require different care than diamonds. Be sure to check out our Moissanite Care Guide to keep your gemstone sparkling for a lifetime.
