Why Grey Spinel?

Grey and silver-toned spinels have become a quiet favourite among designers working in the contemporary fine jewellery space. The colour is naturally neutral and highly versatile — it does not compete with the metal setting, it complements it. Eye-clean grey spinel at over 1ct from Mogok is not a stone that appears regularly in UK stock. It is well suited to minimalist solitaire designs, sleek contemporary earring commissions, and trade buyers sourcing grey colour material for specific briefs.
