General Description:
Elbaite tourmaline is a Sodium Lithium Aluminum Boro-Silicate Hydroxide with
the Chemistry formula : Na(Li,Al)3Al6Si6O18(BO3)3 (OH)4. Elbaite contains many variety names based on color. A beautiful blue variety is called indicolite (also known as indigolite), the pink to red variety is called rubellite, the green variety is known as verdelite, while the most famous variety is a pink and green combination called watermelon tourmaline. Often a specimen can have more than one color zone in the same crystal. These zones can alternate in color from the inside to the outside or from the top to bottom. Elbaite is strongly pleochroic which means that a tran***rent crystal will appear darker when viewed down the long axis of the crystal. A green or blue Elbaite can appear black when viewed from such an angle.

The prism faces are striated lengthwise. In cross section, all tourmalines will appear predominantly triangular in shape with some crystals showing a hexagon when three secondary prism faces are nearly as dominant as the three primary prism faces. Doubly terminated crystals are hemimorphic meaning that the two ends of the crystal are not exactly alike. The terminations on a doubly terminated crystal can have different slants to the pyramids on opposi |
