About Copper-bearing Elbaite
Formula:
Na(Li1.5Al1.5)Al6(Si6O18)(BO3)3(OH)3(OH)
A bluish to green-blue Cu-bearing variety of elbaite. Best-price variants have a neon-blue (electric blue) colour.
This material, when used as a gemstone, has been assigned a new formal commercial trade name by the Laboratory Manual Harmonization Committee (LMHC), a group of 7 gemmological laboratories worldwide - ParaÃba Tourmaline, regardless of locality of occurrence.
