Art Deco 18ct Gold Unheated Ceylon Colour Change Sapphire Ring with Diamond Set Shoulders

78U
Rare Find
Written by Olly Gerrish

A marvellous 18ct gold ring that has been set with a colour change sapphire that weighs nearly four carats. On either side is a small old mine cut diamond. Colour change sapphires are truly a phenomenon. They have the exceptionally rare attribute of changing colours from blue to violet. Colour change sapphires will show one colour in fluorescent lighting and another colour in incandescent lighting. It is like owning two types of stones for the price of one! The ring is accompanied by a gemmological report stating that the sapphire is a natural colour change stone with no indications of heating, originating from Sri Lanka (Ceylon). What a great engagement or dress ring that will be sure to attract attention.

Ollys Pick

Natural colour change sapphires are so hard to find and this one is a large stone!
