WebTAVORITE - "glassy", green to yellow colour stone. or TSAVORITE - green variety of garnet. or TANVORITE - a trade name for a synthetic blue-purple stone. ( to address pupular Tanzanite demand) Post by None I know this is not some just recently discoverd new mineral or gem, so what is it? WebWe investigate the correct structure of tavorite LiFeSO 4 F, which was newly determined. The concentration of intrinsic defects in the tavorite form is very low in comparison with the triplite form. Configurations of FeO 4 F 2 octahedra in the triplite form are in favor of corner-sharing connections over edge-sharing ones.
