Moissanite vs Diamond

Everything You Need to Know About Moissanite Vs. Diamonds

1 to 5 carat Radiant Moissanites

Moissanite is the best diamond simulant on the market today. It looks a lot like a diamond - a little more sparkle but otherwise identical - and is nearly as hard. It costs a fraction of what diamonds do, and many Keyzar customers choose it for their engagement ring’s center stone.

What is Moissanite?

Moissanite is a naturally occurring, rare mineral made of silicon and carbon. It was originally discovered in an Arizonan meteor crater, but natural moissanite is too small for jewelry. Any moissanite you’ll see in a ring, necklace, and other pieces is lab-made!

Moissanite: Advantages

If you’re looking for a center stone that’s hard and shiny but cheaper than diamonds, moissanite is a good choice. It has the following upsides.

Cost

A moissanite stone looks similar to a diamond and costs far less. That means you can go higher in carat weight without paying a fortune.

Looks

Durability

After diamonds, moissanite is the most durable gemstone around. It has a rank of 9.25-9.5 on the Mohs hardness scale (diamonds are a 10). It doesn’t scratch, tarnish, or rub out like many other gemstones.

Sustainability

Moissanite is 100% lab-grown - never mined - so it’s both sustainable and ethical.

Moissanite: Disadvantages

Moissanite is the best diamond alternative, but it’s not quite a diamond. Here are some differences you should be aware of. Can you guess where is the moissanite and where is the diamonds? The diamond is above.

The Science Behind Moissanite

Moissanite is a rare jewel. It’s only found in corundum deposits, kimberlite rock and some meteorites. The moissanite you can buy for your jewelry is 100% artificial and is actually carborundum or silicon carbide; not natural moissanite.

Most of the real moissanite we know about is flying around in space. It is found in dust clouds formed from carbon. Studying the Murchison meteorite prompted scientists to find that silicon carbide, which moissanite is mostly made up of, was formed far beyond our Solar System.

The History Behind Moissanite

1 to 5 carat Cushion Moissanites

Thousands of years ago, The Diablo Canyon meteorite fell in what is now the USA. In 1893, the French chemist Ferdinand Frederic Henri Moisson began to actively study this cosmic guest. He discovered the smallest fragments of a completely new mineral, later named "moissanite" in his honour.

On February 28, 1893, Edward Goodrich Acheson patented the formula for the production of a synthetic analogue. He invented powdered silicon carbide (SiC). This led to the large-scale production of carborundum, because Edward also invented a furnace in which synthetic material is produced to this day. Edward Acherson became the founder of the specialized company, "The Carborundum Company".
