Euclase Pegmatite, Boa Vista, Rodrigo Silva District, Ouro Preto, Iron Quadrangle, Minas Gerais, Brazil
Found in 1993, this gemmy full crystal of euclase hosts the rare teal color. The Boa Vista area euclases are noted for producing. Most of the pieces from this area are white to very light colored, but this piece is a richly saturated gem. The top termination is intact and complex. This is a fantastic thumbnail specimen of euclase. It blew my mind when I first learned that euclase is a decomposition product of beryl and likely emerald. For everything to happen in proper sequence to form these true and underappreciated gems must be near miraculous. This piece is from two old collections and has an accompanying card. There is some minor bruising to the bottom of the piece, but overall is an exceptional example of euclase and from this locality.
