Small chunk of Gypsum with micro crystals growing on it 4″ x 3″ x 3″

Medium chunk of brown-tan chert measuring approx 6″ x 3″ x 2″

Large cut chunk of chert or agate, 3 faces smooth cut measures approx 5″x4″x2″

Raw chunk of Black Tourmaline 4x3x2

Top quality Tanzanite crystal. A very well-formed specimen, saturated coloration, and a very apparent blue-purple color shift. Front and rear faces have a smooth, glassy luster, striated on both sides where a very apparent blue-purple color shift can be seen.

Old stock (30+ years) bi-color elbaite tourmaline cluster. Clean, well-defined striations on all sides and a contact etching that houses a full-spectrum refraction best seen under LED lighting. “Spikey”, clustered terminations on all the formations. This piece is a prime example of the high-quality material Brazil has to offer. It also attests to the infamy of the Cruzeiro Mine and its production of the most sought after material on the market.

Double terminated rubellite tourmaline w/ well-defined and clean striations on all sides. A complex primary termination and a smooth, glassy secondary termination. Three saturated, contrasting color zones and very unique formation make this a true collector’s piece.
