Legrandite
stock #Alec-12-500
Mina Ojuela, Mapimi
Durango, Mexico
4.5 x 3.4 CM (miniature)
price: $480
Spring 2013

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.
Datolite (faceted stone and rough crystal)
stock #JY-001
Lane Quarry Westfield
Massachusetts, United States
Crystal 2.3 x 1.9 CM, Stone 8x8 MM, 1.6 Carats (thumbnail)
price: $260
Spring 2013

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!
Datolite on Prehnite (optical grade gem crystals)
stock #JY-002
Lane Quarry Westfield
Massachusetts, United States
10.6 x 6.7 CM (cabinet)
price: $725
Tucson group

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)
stock #6.2-648
Xianghualing Mine, Linwu County, Chenzhou Pref.
Hunan Province, China
6.6 x 3.1 CM (small cabinet/ large miniature)
price: $125
Spring 2013

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.
Beryl (slender, tapered termination gem crystal)
stock #A7-056-693
Colatina
Espirito Santo, Brazil
4 x .5 CM (miniature)
price: $250
Spring 2013

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.
Silver (arborescent, fine crystallized)
stock #A7-064-556
Kearsarge Lode, Houghton County
Michigan, United States
4.8 x 1.6 CM (miniature)
price: $900
Spring 2013

A very delicate and elegantly crystallized silver with exceptional for for the locality. From the Kearsarge lode this is not typical at all and is a remarkably well prepped and presented tree of fine spinel law crystals and feathery branches. ex Larry White collection, a fine old time piece!
Huelandite on botryoidal Quartz.
stock #9.1-253D
Jalgaon District
Maharashtra, India
9.8 x 7.2 CM (cabinet)
price: $550
Spring 2013

Ex. Doug Ervin collection, Ex Collector's Edge. The mineral market is flooded with average quality traprock specimens, so we avoid most Indian Zeolites unless they are especially good. This one is one of those few! Perfect, undamaged, sharp, well composed and a great example of the specie. Far better in person the esthetics are top notch.
Scorodite (with Beudantite?)
stock #Alec 10-595
Mina Ojuela, Mapimi
Durango, Mexico
4.7 x 3.6 CM (miniature)
price: $285
Spring 2013

A nice sized vug of rich gemmy blue Scorodites in a hard (not crumbly!) matrix. Micro brownish spheres are noted that are reputed to be Beudantites but look much like Carminites to me, either way, a nice addition. In excellent condition, with magnification it is possible to see through the very clear blue crystals to the brown matrix below! A Mexican classic, these are rare on the market and this is a good example.
