Dioptase crystals to 5mm on matrix. Good sized specimen with good coverage, loaded with bright undamaged crystals. One of the best specimens from this occurrence I've seen.

Intergrown pair of crystals of Almandine replaced by Chamosite (the iron analogue of Clinochlore in the Chlorite group of minerals) from the upper peninsula of Michigan. Good sized with crystals to 3.5 cm (most found were less than 3cm). The old label indicates it was in the Frank Hess collection and identified it as 'Aphrosiderite', however Aphrosiderite is an obsolete name and Chamosite is the correct species name. I only have the Hess label, but this specimen is also shown on the Arkenstone website and indicates it was from the historical garnet collection of SMITH COLLEGE, Northampton, Massachusetts and ex. Dr. Gary Hansen Collection.

Terminated single gem crystal of Chrome Tourmaline which is a chromium and vanadium rich Dravite. Complete all around with deep emerald green coloration. Fantastic color. Undamaged. From a spectacular pocket opened in 2016.

Large single crystal likely from the Milpillas Mine. This was shipped to me directly from Mexico from a miner who claimed it was from Sierra Rica, however it looks more like a Milpillas Mine crystal. At any rate, it's a big, showy single crystal crystallized on all sides, front and back, with some bits of matrix intergrown in areas.

Bright yellow Sulfur crystals to 1.2cm that contrast well against the white matrix. Good coverage of crystals.
