Why Choose Interstella Diamonds

Interstella Diamonds are the next generation of lab created Moissanite, the gemstone that is re-inventing the Diamond industry.

  • Conflict free
  • Eco friendly
  • Affordable Luxury

Lab-grown Moissanite Diamonds have several great features that make them an ideal choice for socially and environmentally conscious brides and grooms to be. Our next generation Moissanite diamonds are up 80% percent less expensive than mined diamonds, have extensive options for customization in size, cut, clarity, and colour, while still maintaining similar chemical composition of a natural diamond. Mined diamonds from heavily sourced, conflict-zone locations further pollute the surrounding environment and often place mineworkers in danger conditions for shockingly low wages. In contrast, the lab-grown Moissanite diamonds we work with are created in a highly efficient factory. No water or air pollution result from their production and only a modest amount of energy is consumed.


Moissanite is the name given to naturally occurring silicon carbide and to its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893.
Fire (Dispersion) One of the most distinguishable elements of a Moissanite gemstone is its “fire” or dispersion. … Dispersion is a property of the Moissanite gemstone caused as light radiates through the gemstone on certain wavelengths—each wavelength producing a specific colour. Interstella Moissanite’s are cut to perfect specifications to give the best fire possible.
