Moissanite is a gemstone born from the Stars. It was first discovered in 1893 by a French scientist named Henri Moissan, who later won the Nobel Prize in Chemistry. He discovered microscopic particles of the gem that would eventually bear his name in Arizona, in a crater created by a meteorite that fell to Earth. He initially thought that he had discovered diamonds, but later determined that the crystals were composedof silicon carbide. On the Mohs scale, moissanite scores a 9.25, a very good score that makes it one of the hardest substances on earth, and very suitable for everyday wear but primarily as an engagement ring. Diamonds are the hardest known mineral and received a 10 on the Mohs Scale of Hardness. Moissanite has a refractive index from2.65 – 2.69, which is higher than a diamond. This means that it gives a greater sparkle than a diamond. A gemstone’s fire is determined by a geological property called dispersion. Dispersion refers to the prism effect that occurs when pure white light enters a non-opaque object, breaks into spectral (rainbow) colors, and reflects back to the viewer. Moissanite’s dispersion is0.104, which exceeds that of any gemstone including diamond, ruby, sapphire andemerald. Because moissanites are lab created,they are an appealing option for those seeking an eco-conscious gemstone asthey require no mining. Moissanite grading uses a color gradingscale that is based upon the GIA diamond color grading scale. There are threegrades of moissanite available today: colorless (D-E-F range), near-colorless(G-H-I range) and with faint hues of color (J-K range). When you purchase one of rings we provide you with certification that our Moissanite is graded with a clarifty of VVS D range, making it the highest grade of colourless.They are 925 Sterling and Platinum Plated You will also receive a luxury blue velvet jewellery box and free secure registered posting.
