Moisonite
Among the many simulants manufactured to substitute for natural diamond, Moisonite is probably the most successful at duplicating the beauty of the diamond. Moisonite is a synthetic, lab created mineral (SiC) silicon carbide. This artificial gemstone is manufactured by Charles and Colvin. Its optical properties make it have greater brilliance than natural diamond. When cut in the proper proportion and angles, the higher refractive index and dispersion of light, give moisonite a brilliance not matched by other gemstones.
In addition to the optical properties, moisonite has a Moh’s hardness of 9.5, making it harder than rubies and sapphires (corundum). 
The combination of optical and physical properties make this gemstone a great stone to use in jewelry. You will get more information at pruittvillefarms .
Diamond testers that were designed to detect earlier simulants (cubic zirconia, GGG, YAG) can not distinguish between moisonite and natural diamond. A tester that measures both heat conduction and electrical conduction can determine the difference.

Beautiful stones and informative post, as usual! Thanks, John!
Interesting article and beautiful stones.
Nice article!
Moissanite is very interesting stuff. You might be interested to know that while the Moissanite that is on the market is man-made, it does actually occur naturally just primarily in space (the crystals found on earth are really tiny and too small to use except to help labs grow larger crystals).
You are quite correct, in fact, the first naturally occurring moisonite was discovered at Meteor Crater in Arizona, by Moison. The mineral was created by the energy of the impact. I did not mention natural moisonite as for a gemologist this is not a matter that makes any difference as the only cut stones are of the synthetic variety. Thanks for adding to the blog post.
Great post as always John!

Very nice post John. Another point that many do not realize is that the brilliance of a moisonite stone is guaranteed for life. When purchasing this beautiful diamond simulant you should receive a Charles & Colvard “Certificate of Authenticity” and limited “Lifetime Warranty” card. Every stone comes with its own card and warranty ID number; the customer than in turn needs to call or register their stone(s) online.
