0.68 carat Montana Sapphire Color Change (Heated)

Color changing gemstones are exceptionally beautiful! This particular Montana Sapphire is a periwinkler blue with a touch of violet in natural lighting. When under incandescent lighting, it turns a soft rose-violet. I've sat and studied this stone a lot since cutting it and look forward to the day its set in an equally beautiful setting. I cut the raw material in half, hoping to get a matched pair, but the second half decided to have a slightly different color change than its partner.


I cut this lovely Sapphire in a design called “Ruination,” written by Arya Akhavan.


It is eye clean and has been heated.


Sapphire has been popular throughout history, and that trend doesn't seem to be changing. Sapphire is a mineral called corundum, and it doesn't only come in the well-known royal blue. Corundum comes in an array of colours and shades, including white. The popular Ruby also belongs to this family as a red corundum. Sapphires and Rubies have a hardness of 9, making it the hardest coloured stone, and is well suited for daily wear.
