Why Grey Spinel?

Grey spinel has a growing following among jewellery designers who want a neutral-tone centrepiece that stands apart from the usual colourless diamond or blue sapphire brief. The colour is naturally subtle but not uninteresting — it has depth and a quiet elegance that photographs well and wears with almost any metal colour. Eye-clean grey spinel at 1.37ct from a Mogok provenance is a commercially interesting stone for trade buyers and bespoke makers alike.
