This pretty Sapphire comes from the Umba Valley in Tanzania. It's soft color is unheated, untreated, and completely natural. In daylight, the color appears
slightly more reddish than an Amethyst with a halo of salmon pink. In incandescent, it is a vibrant purplish red.
I cut this gem attempting to cut out the heavily included portions in the rough material, resulting in this beatiful modified trillion design.
This Sapphire is untreated which can be seen by the fine rutile needles within.
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. Sapphire also happens to be the traditional birthstone for those born in September.
