In natural light and most in-door lighting this sapphire is a lovely medium toned teal/green, however under certain artificial white light it changes to a grey/purple or a mix of teal and purple. Not only does this sapphire colour change in white light, it also fluoresces red in Ultraviolet light. This sapphire would suit a collector of gemstones or someone looking for an heirloom bespoke piece of jewellery. Our qualified designer has a number if wonderful ideas that could be considered.
Sapphires are the second hardest natural gemstone after diamond. Hardness is very important if the piece is to be warn daily, as in the case with an engagement ring.
