Tanzanite is a December Birthstone.
Looking at its blue to bluish purple to bluish violet, you won’t believe that the mineral (zoisite), actually, occurs in a wide range of colors from colorless to yellow, brown, green, pink, blue and violet.
It’s found in only one place on earth in Tanzania, near Kilimanjaro. That is how the gem got its name due to Tiffany&Co. Tanzanite is pleochroic, showing different colors when viewed from different directions.
Almost all Tanzanites on market today have Heat treatment. It is heated to improve or produce the desirable blue color. Vivid Blue, Violet blue and Blue Violet are the most valuable Tanzanite colors.So often people mistake it with Blue Sapphire.9500
