this time we can observe growth structure (trigons) on a very deep green chrome crystal of Tourmaline. 350 ct and about 44 x 40 mm specimen. They are very diamond like termination. to be remembered that Tourmaline has a trigonal symmetry.
That isn’t a Pokémon. and a pretty fine one, that too. Inspired by quartz, and built using an intricate mathematical algorithm derived from the mineral’s complex crystalline structure, the armchair comprises of a wooden frame and geometr
