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 #AX-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.
Pink Fluorite with Clinozoisite, Rhombic Adularia, Clinochlore etc.
stock #AX-10-723
Villadossola, Verbano-Cusio-Ossala Province
Piedmont, Italy
6.5 x 5 CM, Crystals to 6.5 mm. (cabinet)
price: $360
Spring 2013

A fine alpine cleft Pink Fluorite that is NOT Swiss or French but a much rarer Italian Piedmont piece! With magnification this is especially striking, the octahedrons are glassy, sharp and show complexities, they are set in a vug lined with spikey Clinozoisites and glassy rhomb form Adularia. All with a sprinkle of bright green Clinoclore (Amesite?). Very rare to see any of these for sale this is an especially nice older specimen of pre 1960 vintage. Ex Bill Hlaydsz collection.
Adamite (spherical aggregate)
stock #10.1-178
Mina Ojuela, Mapimi
Durango, Mexico
4.4 x 4.4 CM (miniature)
price: $950
Spring 2013

Mina Ojuela has produced loads of nice Adamites, (it is the world's best locality for the mineral) but really great ones are very uncommon and prized. This one is top quality. The most desirable form of Adamite is the Spherical radiating pinwheel of brilliant lemon-green color from Mina Ojuela. This is a impressive, fine specimen with a lustrous damage-free sphere. Great esthetics and color, this had been in the collection of Ernie Schlichter. A very good value for this quality!
