18ct Gold & Platinum 18ct Gold Cluster Ring set with a Mint Green Tourmaline & Diamonds by Charles Green & Sons

690Y
175 Admirers

An unusual 18ct gold. ring that was made by Charles Green and sons in 1963.  It has been set with a beautiful mint green tourmaline which is technically a chrome tourmaline as it exhibits a colour change from a light forrest green to a mint green.  Colour change in chrome tourmaline is primarily caused by the presence of chromium and the unique way the gem absorbs and transmits light. Around it are sixteen small diamonds that compliment the stone beautifully.

A gorgeous ring set with such a stunning tourmaline that can be worn as an engagement ring.
