Fornacite on Dioptase (Type Locality) (Ref: 20-FC-115)

Reneville Mine, Reneville Kindanba District, Pool Department, Republic of Congo (Brazzaville)
40mm x 33mm x 25mm
minID: AFH-TDY
Fantasticly rich, dense clusters of Fornacite crystals on Dioptase crystals. Fornacite is a rather rare mineral but nearly always seen just as micros with very small isolated crystals. This is an amazingly rich specimen with eye visible crystals in groups that are up to 2.5 CM across! The matrix is an attractive mix of Dioptase crystals and balls of Plancheite. The crystals are lath shaped and many are free standing, most are a dark olive green ranging to as brownish yellow with backlight. Under strong magnification a few dark green balls are seen that may be Mottramite but are not identified. From the type locality, this is a superb and important piece for this rarely displayed mineral. None of us have ever seen any piece with so much of the specie and so easily seen.
