Does anybody know what type of stone these cufflinks are made of? Thank you!
They look like Red Goldstone to me. Goldstone is a man-made type of glass and comes in red, brown, blue, green, and purple (maybe others too). It is made of melted silica sand that has flakes of copper mixed in, as well as different chemicals or minerals that give the color to the resulting "glass". When in the molten state, it can be formed into many shapes using molds.
These are most likely 'man made' faux stones but without a brand name on the original box, it will very difficult to identify the exact material.
They look like some kind of quartz to me
What brand are they? I see the box. At a glance they look like Lucite. Can you show the clasps? The clasps can tell you a lot of info usually.
Thanks!
