Pyrophyllite - very well crystallized
Indian Gulch Mine, Santa Cruz Mountain, Hornitos Mining District, Maripo
13.6 x 9.3 x 8.2 CM (cabinet)
Pyrophyllite is not often seen in an esthetic, collectable grade mineral specimen but it can be striking. This is both a huge specimen for this specie and an exceptional one, the best I have ever handled. Large radiating clusters reach 4 CM across. This piece was sold by the Schortmann brothers almost 70 years ago (their label did not survive) and was in the Cook family collection on display since then. The Pyrophyllite crystals are in sprays some of which are above the matrix and show terminations which is very rare. Shining golden metallic luster is seen on all sides except the base where this was removed from the host rock. In extraordinary condition and brilliant in person, from a long closed mine, an important piece, as fine as this specie gets.
Incredibly perfect spinel twins of Galena showing mirror bright luster standing on edge. In my own opinion the top spinel Galenas from Bulgaria are the best on the planet, and every serious collection should have at least one. From the 2011 find at the Krushev Dol Mine these Galenas were instantly big news in the mineral world. Aside from obviously fine esthetics, this piece is even more remarkable for the damage free condition. Under good magnification the galena edges are all complete (some have a more jagged edge crystallization but no damage or chipping) even the slender Quartz crystals are all perfect. The faces of the Galenas are a super brilliant metallic even brighter in person. The crystal forms are incredible too, the largest sides show fantastic geometric growth structures and textbook twinning. This was a large find so the cost of a nice piece was quite reasonable but very few pieces were this good, and now they have become uncommon.
Daoping Mine, Gongcheng County, Guilin Prefecture
5.4 x 5.2 x 2.8 CM (small cabinet/ large miniature)
Pyromorphite can be an incredibly beautiful mineral, the best having great color, luster and form. This piece is certainly a fine one from the great Daoping Mine which many consider to be the greatest locality for Pyros in the world. This from one of the last good finds for the bright green unaltered type in 2017. More recent materials have much less bright color and are often at least partly altered. Crystals reach 1 CM on this piece in isolated prisms and radiating clusters these have both pointed terminations and the hollow hoppered tops so well known from this mine. In incredible condition, good Daoping Pyromorphites are one of the modern mineral markets best values. This one is especially so and it displays well from almost any angle.
Calumet Mine, Turret District, Chaffee County
6.8 x 5.2 3.3 CM (cabinet)
A plate of Epidote that shows two different colors and has a few bi-color crystals. In very good condition the crystals reach up to 1.5 CM though most are smaller. Most crystals have gemmy faces, are transparent and have a yellow to dark green color range. From the old Calumet Iron mine in Chaffee County Colorado, this is above average for size and quality of the crystals on matrix. Many of the crystals are well striated with very sharp and distinct forms.
Fluorite on Stibnite
Banpo Mine, Dushan Co., Qiannan Pref.
6.7 x 6.7 x 3.5 (cabinet)
Purple to blue "melted" or tiny rounded crystals of Fluorite are covering a radiating mass of metallic Stibnite crystals from a find at Dushan almost 20 years ago. Similar to the Fluorite on Stibnite from Thailand that was found nearly 50 years ago, these are the only discoveries ever made of this sort. and both were small. Fluorite on Stibnite like this are only rarely found in the mineral market today. This is a choice small cabinet with most Stibnite having sharp terminations seen where they extend from the enclosing Fluorite. The backside of this piece has some minor bruises but that side is less attractive regardless, the front is showy and displays perfectly.
Adularia with Chlorite
St Gotthard, Central St. Gotthard Massif, Leventina
8.7 x 6.4 x 3 CM (cabinet)
Fine Swiss Adularia crystals up to 2.4 CM with green zoned inclusions of Chlorite are well presented on the matrix. From the type locality (St Gotthard) Most of these crystals have a slight dusting of Chlorite on the outside as well but the majority of the faces are glassy and transparent. Very pleasing esthtetics from almost any angle this is a choice and showy specimen of a usually unimpressive specie. No damage which is incredible for a piece with this complexity. Excellent Alpine classic that shows the textbook monoclinc form perfectly.
A super impressive and very unusual radiating fan or "wheatsheaf" clustering of chisel terminated Barite. Frizington Barite (or Barytes) is one of the great classics on the mineral world. One of the special features of good Barite from Frizington is their Bicolor nature. On this piece zoned inclusions of Hematite give a red color to edges of the prisms while the core and some terminations are a bright blue. Only some very minor edge wear can be seen and is not evident on display, overall in excellent condition which is impressive for an old classic.
Amethyst- conjoined scepters
Orange River, Namakwa
2.1 x 1.4 x 1 CM (thumbnail)
A sweet thumbnail of sharp transparent Amethyst scepters that share a single stem. Both crystals show a double termination and grade to colorless lower down. From a find a few years ago at Orange River (Namibia), there were not many of these. In fine condition as seen, and a bit nicer in person too.
