Read MoreThe same brilliance as natural gemstones, created responsibly.
Lab grown gemstones, also known as synthetic gemstones, possess identical chemical, optical and physical properties to their natural counterparts — indistinguishable beauty in every facet.

Conflict-free and environmentally responsible — lab grown gemstones are created without destructive mining.
Gemstones can be created using various techniques, much like lab grown diamonds. One of the most common and oldest methods is the Flame Fusion (or Verneuil) technique. This process involves dropping powdered chemicals through a high-temperature flame, where they melt and fall onto a rotating pedestal to produce a synthetic crystal. It is widely used for creating gems such as synthetic corundum — which includes both sapphire and ruby gemstones — and spinel.
This process is particularly effective for creating emerald, sapphire and ruby. Overall, these methods provide a reliable means of creating a wide range of colored gemstones with consistent quality and characteristics.
