A cream colored doubly terminated prismatic augelite crystal of about 2 cm on a limonite matrix with a few other smaller augelites. Selected from a lot of about 500 other specimens of Augelite. Machacamarca is one of the earliest silver mining districts in Bolivia. It is credited with having the first bank in all of Bolivia, even before Potosi. It is built up and down a little tight canyon with mine dumps spilling into the canyon from both sides. The scale under the specimen is an inch with a rule at one cm.

A high domed cabochon of transparent light colored smoky quartz with a flat window cut on one side showing a thin hexagonal black crystal of hematite about a cm in diameter growing up into the quartz. Selected from a ~50 kg lot of polished quartz with inclusions in Curvelo, Brazil. One would think that the specimen is from the sand stone area in Minas Gerais rather than the pegmatite area. The scale under the specimen is an inch with a rule at one cm.

A hand sized polished nugget of chrysocolla, malachite and other minerals. This massive material has been mined in Ica since the 1970s, A lot of it was sold to customers in Israel to be cut up and sold to tourists as Elat stone which was a similar material that in ancient times was found in the region. It is still being dug and cut and polished into balls, eggs and other lapidary items by lapidaries in Lima. The quality is highly variable. The scale under the specimen is an inch with a rule at one cm.

A blocky amazonite crystal of good color on a bit of albite with a little dirty albite. We never got the albite on this specimen as clean as we should have before we dipped it in paraffin. The amazonite has some little sparkling secondary microcline on it. Perhaps ten to twenty percent of the crystals from Ethiopia in our first large shipment has this sort of secondary sparkle effect.

A good bright red 4 cm crystal on matrix. X Fred Devito collection 2004. Fred collected the specimen on April 17, 1972. A bunch of us guys were on the same trip and we sure didn't get any specimens that good. The deposit has since been open pitted in two separate digs for wulfenites down most of the way to the haulage level and it is doubtful that few if any more specimens will come from this famous old mine. The scale under the specimen is an inch with a rule at one cm.

Rowley Mine, Theba, Painted Rock Mining District, Painted Rock Mountains, Maricopa Co., Arizona, USA

Dimensions: 30 mm x 20 mm x 15 mm
Weight: 6.5 g

A high quality TN specimen of wulfenite with the main crystal about 1,5 cm. Good specimens of wulfenite from this mine are rare & hard to get. The crystals are so thin and delicate that not many good ones survived the mining process and the tender care of collectors over the years. The weight given for the specimen includes the stand. The scale under the specimen is an inch with a rule at one cm.

Gemmy green vivianite crystals perched on a bit of red sandstone matrix. Got the shipment as part of a 1000 piece shipment from Bolivia. Even though we got in several large shipments of vivianite, the number of really transparent sharp green crystals like this one was very small. Less than 5% I would estimate. The scale under the specimen is an inch with a rule at one cm.
