Conflict-free and environmentally responsible — lab grown gemstones are created without destructive mining.
Yes. Utilising advanced laboratory techniques, lab grown gemstones — also called synthetic gemstones — are chemically, physically and optically the same as their natural counterparts. The only difference is their origin: born in a controlled laboratory rather than deep within the earth.
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.
Another prevalent technique is Flux Growth. In this method, the chamber's temperature and chemistry are meticulously controlled over six months to a year to mimic the natural environment where the gemstone originates. During this time the crystal grows on a 'seed' in its natural crystal shape. Excluding the foreign materials found in the earth, this controlled environment ensures more predictable growth and consistent quality and colour.
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.
