This page gathers the gemstones in our collection whose character is expressed in grey — from the smoky, metallic neutrality of spinel to the silvery sheen that plays across a moonstone. Grey is not an absence of colour but a restrained one, and it suits settings where the metal, the cut and the wearer are meant to lead.
Here you will find Grey Spinel, valued for its clean, even body colour and bright, singly refractive lustre; Grey Tourmaline, which often carries a subtle greenish or brownish modifier and reads differently by axis; Blue Moonstone, a feldspar whose greyish body is the backdrop for adularescence, the floating blue light for which it is prized; and Star Sapphire and Blue Star Sapphire, corundum cut as cabochons so that fine needle inclusions can return a six-rayed star.
When choosing, weigh transparency against phenomenon. Faceted grey stones are judged on clarity, evenness of tone and cut precision; cabochons are judged on the sharpness and centring of the star or the strength of the sheen. Consider how each behaves under the lighting you wear jewellery in.
