Out of This World Brilliance

Moissanite is a precious and rare gemstone originating from an asteroid that crash-landed on earth in 1893. The unearthly-occurring process of creating this brilliant gemstone is duplicated in a lab through a combination of intense heat and pressure. This has resulted in optical qualities that are out of this world, with sparkling scintillation just one of this gemstone’s many properties. Moissanite is also extremely hard (9.5 on the Mohs scale), meaning moissanite stones will endure a lifetime and beyond.

Moissanite FAQs

Moissanite is worth buying for its lasting beauty, cost-effectiveness and conflict-free origins. As a lab-created stone, moissanite involves no mining and its origins can be easily traced, making this a sustainable choice of gem. Moissanite is significantly lower in pricing than diamonds of the same size and quality, allowing you to purchase your dream ring for the fraction of the price! With a high clarity grade and a hardness rating of 9.25-9.5 (second only to a diamond at 10), your moissanite stone is extremely durable and will retain its sparkle throughout everyday wear. At Cullen Jewellery, we are so sure of this that we provide a lifetime warranty to guarantee the lasting brilliance, colour and clarity of your gorgeous gemstone. Read more
Yes, moissanite will pass a diamond tester. Moissanite and diamonds conduct heat in very similar ways, and since diamond testers measure thermal conductivity, moissanite passes as a diamond. A specific Moissanite tester that uses electrical conductivity can be used to distinguish the difference between a moissanite and a diamond.However, the easiest way to find the difference from a diamond and moissanite is to use a loupe to look through the top of the jewel at an angle. Moissanite stones will show two slightly blurred lines, indicating a double refraction – this is moissanite’s unique attribute. Read more
Moissanite is not a fake diamond, but a real, beautiful gemstone in its own right. Although often compared to a diamond for its similar appearance, moissanite is a lab-created stone with high clarity, hardness and fire. Unlike cubic zirconia, which is a man-made stone used for fake diamonds, moissanite is extremely durable and is suitable for a lifetime of everyday wear. The dazzling sparkle and lasting beauty of moissanite makes it the perfect alternative for customers who want the look of a diamond without the expensive price tag or questionable ethics. Read more
While moissanite has a diamond-like appearance, it is not a fake diamond and is in fact a beautiful, unique gemstone. When light hits a moissanite ring, the surface of the stone sparkles with a rainbow, almost disco ball effect. This makes moissanite more vibrant than a diamond, but it is not to the point of looking fake. The sparkle and fire of moissanite is what attracts moissanite lovers and here at Cullen Jewellery, we say the more sparkle the better! Read more
No, moissanite does not lose its sparkle. Due to its superior hardness, clarity and refractive index, moissanite will remain bright and sparkly forever. Over time, oils and dirt can build up on the surface of your stone but this can be easily cleaned away, either by a professional or at home. At Cullen Jewellery, we guarantee your moissanite’s lasting brilliance, clarity and colour with a lifetime warranty – so you never have to worry about your moissanite losing its shine! Read more
