Mimetite (classic wet botryoidal)
San Pedro Corralitos, Municipio de Casas Grandes
3.8 x 2.1 CM (small miniature/ large thumbnail (toenail))
From the most desirable early find (1968-69) at San Pedro Corralitos, this is a very lustrous "wet" looking yellow Mimetite. A little larger than a thumbnail, this specimen has a lot of eye appeal despite its size. No damage, great color and form, the quality of these first specimens was never seen since then- despite more than 40 years of looking!
A dense cluster of shining crystals with some mixed sulphides sits on a crystallized calcite matrix. Color is fairly dark but good light on some areas picks up the expected red colors of the Pyrargyrite. The Calcites also have red inclusions that may be ruby silver too. Largest xls are about 4-5mm, many are damage free. The loupe also finds one very small elongated red crystal near the bottom that looks more like a Proustite. A good European classic location piece.

Kamareza, Laviron Mines,
Attiki Prefecture Laurion District,
9.1 x 4.7 CM (cabinet)
From one of the earth's oldest mineral localities this is a pretty, bright color densely crystallized plate of Cuprian Adamite. In outstanding condition, this thin plate hosts hundreds of perfect crystals. With 10x magification I can find only 2 tiny bumps. A classic locality piece with top color.
Mina Ojuela, Mapimi
4.5 x 3.4 CM (miniature)
One of the most desirable rare minerals from Ojuela, Legrandite well displayed in a radiating burst of distinctive yellow. This is filling a shallow pocket in the gossan matrix,2.8 CM across. Several prismatic crystals are compleet here but there are several broken ones too (legrandite is especially brittle and and there are almost no specimens of any size without some damage). Despite the damage this is still well above average. None has been found for over 20 years now, this is an early piece last sold in the 1970s.
A classic old locality! This is quite a nice and rare combo, from the Lane Quarry in Massachusetts. Cut and rough combo with a fine faceted stone of light yellow color and excellent clarity. Datolite is a rare gemstone and it is difficult to cut as the hardness varies in different orientations, but when done well they are brilliant! Datolites can have a dispersion greater than diamond. The crystal is bright, sharp and un-dinged on the display side, contacted on back and broken on the base, it displays well. Very uncommon to see a Massachusetts Datolite combo like this!
Impressive and a Northeastern US classic! Sharp, clear and bright gemmy Datolites up to 2.4 CM with selective faces colored a nice cognac hue sit on a contrasting green Prehnite. As esthetic as you can find, the main crystals are in perfect condition but non detracting damage is noted on a few smaller crystals and at the edges. Despite this it displays very well and is a striking specimen from this old locale.
Fluorite (complex cubo-octahedral)
Xianghualing Mine, Linwu County, Chenzhou Pref.
6.6 x 3.1 CM (small cabinet/ large miniature)
An older (2001 vintage rather unusual form of fluorite from a location that was once prolific. We see almost nothing now from Xinghauling and this small find had unique esthetics. Excellent condition and color, displays well from every side, with bright luster.
From an old small find of these exotic, tapered habit gem beryls, this is a very nice, clean example. Excellent condition, with great texture, color and form, this is not a typical Beryl at all! Ex Larry White collection.
