Two gems for the price of one!
Working on this phenomenal piece of Color Change Sapphire rough, from the Umba Valley, Tanzania, which is currently 24.51cts after some sawing and fashioning.
Completely natural with no treatments of any kind. This gem is blue in florescent light and turns to purple in incandescent light.
One of our favorite stones to work with, when we can get our hands on a gemmy piece.

Two gems for the price on one!!
Phenomenal blue to purple change in this 12.24cts Color Change Sapphire, briolette cut, 15.0×10.0mm.
Scroll across to see its color in daylight, or better yet come and see it in person at AGTA 900 in Las Vegas….!
Natural, untreated from the Umba Valley Tanzania. The image on the left is under florescent light and on the right is the same gem under incandescent light. This gem displays flashes of both colors in daylight, which can be considered a third color.
Small inclusions that are eye-visible don’t significantly affect the price when it comes to phenomenal gemstones like these – the beauty and strength of the change is far more important.
Sizes above 5cts with good change are very rare.
Sapphires and Rubies are the same mineral – corundum. When corundum is red it is called ‘Ruby’; when it is any other color it is called ‘Color” followed by ‘Sapphire”, e.g. Blue Sapphire or Pink Sapphire.
Corundums are found all over the world with principal mining locations being Sri Lanka, Burma, Madagascar, Thailand, Australia, Tanzania, Kenya, USA (Montana).
Sapphires are September’s birthstone and their variety of colors offers so much choice! They also celebrate the 5th and 45th Anniversaries.
