This is a significant cluster of Synchysite-(Y) from the little known Mula Mine in the Bahia state of Brazil. Synchysite-(Y) is a very rare calcium-yttrium fluorocarbonate and these crystals are huge for the species! The cluster consists of several, stout, well-formed, pseudohexagonal crystals between 1 and 2 cm in maximum dimension. Some of the subby prismatic crystals show slight tapering at their terminations. The crystals of Synchysite-(Y) are actually an opaque, creamy white and have a dove-gray coating of an unknown mineral. This distinction is revealed from minor contacting on the underside of the piece and a compromised termination on the top that reveals internal zoning of at least this crystal. This is one of the finest and largest clusters of this mineral that we are aware of and the Mula Mine is a surprising gem of a deposit given the well-formed rare-earth carbonate specimens it has produced, Parisite in all its varieties is a very rare, rare-earth carbonate and this locality has produced, in very small quantities. This is from the multigenerational personal collection of Brazilian mineral dealers Bruno and Rolando Gioia, sold recently after the passing of Rolando. Both are well known collectors and contributors to the book Minerals of Brazil.
