1.58 carat Montana Sapphire Aqua Blue (Heated)

A beautiful Montana Sapphire heated to the shade of Aquamarine. I'm very excited about this particular piece and how well it turned out. It would be the perfect size for a center stone in a ring.


I cut this Sapphire in a simple step cut to showcase its amazing color.


This stone is eye clean.


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.


We purchased the rough stone directly from the local Montana miner. He ensures his employees use environmentally conscious practices with minimal impact to Montana's rugged beauty. The Sapphires are dug from alluvial gravel deposits along the riverbeds of Montana, and a lot of effort is put in to restore the land to its natural state when finished.
