Tourmaline (Tricolor)Tourmalines are one of the few gems that occur in natural bi color or tri color stones. This stone was cut from a crystal found nearly 40 years ago in Brazil. The stone shows a rich blue green color on one end with a wonderful pink hue on the other end and a beautiful colorless thin "Achroite" zone in the middle. Tourmaline is classified as a "Type 3" gemstone, as inclusions are almost always present, and accepted by dealers and collectors, so the

and completely eye-clean gems are very hard to find

The topmost portion of the piece is quite gemmy

black cyclic twinned crystal group with virtually no damage and decent sized crystals

If the immense rarity of a Bolivian Hopeite was not enough

and certainly worth picking up if you collect copper minerals

You can’t get these pieces anymore

Specimen # BOL711B51

The only real damage is on the back / side of the group

Hard to photograph

Hematite like this is not common from Colorado

Alexandrite is one of the most well-known color-changing minerals/varieties of species extant

which look beautiful with a loupe and even better under the microscope
