Nanocrystal: Blue Sapphire

Rating: Be the first to rate this gemstone

Nano Crystals are a new type of created gemstone made especially for PMC jewellery. The colour is homogeneous, meaning that if you bought 100 emerald green nanocrystal stones, the colour would be exactly the same in every stone. The material has been created with precious metal clay in mind, so any size gem should be kiln safe and blow torch safe with out colour change or damage.
