Cole Thynne on Instagram: "This 22-carat optical quartz is ornamented on a rose engine lathe, where a finely controlled guilloché pattern is engraved into its surface with precision. Rather than faceting on the lathe, the stone’s form is defined first. The engraved geometry interacts subtly with light, creating a quiet brilliance that reveals itself. #gemstone #jewellery #lathe #roseengine #plumier"
