Sapphire Rough
The mineral corundum (sapphire) consists of pure aluminium oxide. Trace amounts of other elements such as
titanium and chromium give corundum their blue, yellow, pink, purple, orange or greenish color. Sapphire includes any gemstone
quality varieties of the mineral corundum except the fully saturated red variety, which is instead known as ruby, and the
pinkish-orange variety known as padparadscha.

glass jars with stones like this and glued on a handmade sterling silver cap with a bail to make attractive pendants that
sell really well. Total weight of this lot is 19.5 cts.
