Product Description
Sapphire is a gemstone, a variety of the mineral corundum, an
aluminium oxide (α-Al2O3). It is typically blue, but natural
"fancy" sapphires also occur in yellow, purple, orange, and green
colors; "parti sapphires" show two or more colors. The only color
which sapphire cannot be is red as red colored corundum is called
ruby, another corundum variety. Pink colored corundum may be either
classified as ruby or sapphire depending on locale. This variety in
color is due to trace amounts of elements such as iron, titanium,
chromium, copper, or magnesium.
