TAL70CDD: Áliva sphalerites are globally renowned for two things: their transparency/color and crystal size. In this case, the crystal size is undeniable, and although its thickness makes the transparency less visible, it boasts well-defined polycrystalline growth, a rarity in these pieces. Damage-free with some matrix at the base.
