What is Moissanite and where did it come from?


A brief history of Moissanite 


Moissanite is a naturally occurring mineral, composed of silicon carbide—first discovered by the Nobel Prize-winning chemist Dr. Henri Moissan, at the site of a meteorite strike in Arizona USA. As a result of his discovery, the stone was named “Moissanite.” 


Natural Moissanite is rare and occurs in tiny crystals, unsuitable for cutting into gemstones. In later years, an innovative process harnessed in a laboratory created silicon carbide crystals, suitable for cutting. 


Lab-grown Moissanite


Today, laboratory-grown crystals, cut into Moissanite gemstones rival the beauty of diamonds for both fire and brilliance. These man-made gems are more durable than any other popular gemstone such as diamond, sapphire, ruby or emerald. Furthermore, their lower cost and ethical standards make Moissanites a popular alternative to diamonds and sapphires. If you would still prefer a diamond, talk to us about lab-grown diamond options available for most of our jewellery designs. 


Moissanite and Fairtrade Gold


We create many of our regular engagement ring styles combining Moissanite with ethical Fairtrade Gold. This combination ensures 100% ethical standards with all materials responsibly sourced from the laboratory and mine.

Brilliance - Moissanite vs Diamond


Many buyers value Moissanite owing to the gemstone’s brilliance, or sparkle. With a higher refractive index than diamond (2.65 to 2.69) Moissanite offers even more brilliance than a diamond.

Starlight Moissanite Colour and Clarity


Moissanites over 5mm in size include a certificate from the Assay office, recorded by Anchor Cert. The unique reference number and the Starlight logo is inscribed on the bezel of the stone. Starlight Moissanites offer exceptional clarity with a minimum F colour whiteness grade

Starlight vs Forever One Moissanite


Starlight Moissanites offer exceptional beauty rivalled by Forever One, but with one important difference. At a fraction of the cost, Starlight provides exceptional value for money without compromise. 

How hard is Moissanite compared to Diamond?


With a hardness of 9.25-9.50, Moissanite is harder than all other gemstones with the exception of a diamond. For this reason, it makes a perfect choice for durability alongside a natural or lab-grown diamond. Also, its resistance to heat makes Moissanite unlikely to suffer damage during jewellery repair.
