Product information

A two-tone cabochon of the rare man-made gem, Victoria Stone.

Also known as Imori Stone after its Japanese inventor, Dr.S Imori, Victoria Stone dates back to the 1960s & is an interesting synthetic in that it is manufactured from a combination of natural gem materials, processed into a fibrous aggregate structure giving these gems a vibrant chatoyant effect.

The precise method of producing these gems is unknown, and since the demise of the inventor high quality examples, like this superb turquoise-blue and pale blue to white gem, are becoming hard to find.
