Our Moissanites

Our Moissanites are sourced from a Hong Kong supplier specialising in lab-created stones. Working closely with the supplier allows us direct access to custom-cut stones that are otherwise hard to source from regular Moissanite companies. As a result, we can have a broader range of creativity and flexibility when creating custom and bespoke rings.

So whether it is a Moissanite as the centre stone or a Sapphire centre stone with Moissanite accents, we are here to create and assist you in bringing your dream ring to life.


Moissanite is a naturally occurring silicon carbide and its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893.  Initially, the crystals were thought to be diamonds, but they turned out to be entirely different materials. To honor him, this magnificent new gem has been named “Moissanite”.

Natural moissanite is incredibly rare. After many years, scientist have been able to take the moissanite particle and successfully synthesize the stone to produce into what we know it for today. 

Moissanite emits more colour flashes than an excellent cut diamond because of its high refractive index of 2.65 (measure of how fast light travels through the stone). It is this unique colour that makes moissanite so special. The optical properties and quality of Moissanites will never deteriorate over time.

All Periapt Studio Moissanite stones used have a clarity rating of VVS2+ (or better) and a colour grading of D/E unless specified otherwise. A stone from Periapt Studio is guaranteed to be eye-clean with no visible inclusions and will conform to the GIA’s standard for colourless diamonds.


Alternatives to the traditional diamond engagement ring are increasingly being explored. Due to their lower price point and flexibility, Moissanites are becoming increasingly popular, so you won’t need to sacrifice your budget to achieve your desired shape and size.


Affordability does not mean poor quality. On the Mohs scale (1-10) of hardness, Moissanites rank second to diamonds and are closely followed by sapphires. Mohs scale determines an object’s resistance to scratching, making moissanite a suitable choice for an engagement ring or bridal set.


Moissanites do not require mining, making them an excellent choice for eco-conscious consumers.
