EPIDOTE, QUARTZ Green Monster Mountain, Prince of Wales Island, Alaska A. More than 10 very lustrous, dark olive green-black, individual terminated Epidote crystals form an attractive group, without matrix. The smallest crystal is 3/8", there are 3 crystals each measuring 3/4’ in length, and the largest crystal is 1"+ long X 3/8" wide. Several Quartz crystals are also present in the group, up to 3/4" tall. Jim Clark collection. Size: 2" X 1 1/4" across, X 3/4" thick Order Item MI-041A SOLD B. This very good miniature size specimen has four terminated, dark green Epidote crystals of 3/8" to 5/8" size in the center of a group of prismatic Quartz crystals. There are probably 20 Quartz crystals present, ranging in size from 1/8", up to 1 1/4" long. The largest Quartz crystal is double terminated, and runs diagonally across the back of the specimen. One of its terminations can be seen directly below the largest Epidote crystal on the left side of the specimen. The largest Quartz crystal, standing up on top of the specimen, measures 7/8" tall. Some of the tips of the larger Quartz crystals have light green Chlorite inclusions. F. Marshall collection. Specimen size: 1 5/8" tall X 1 1/4" wide X 7/8" thick. Order Item MI-041B SOLD |

STIBNITE Kadamdzhay, Tien-Shan Mountains, Kirgizstan (Kyrgyzstan), Uzbekistan, USSR More than 100 sharp, brilliant metallic steel gray, prismatic Stibnite crystals have formed an intergrown group, without matrix or point of attachment. Some of the crystals have distinct terminations, however, most are naturally non-terminated, or the terminations are indistinctly formed. The largest crystal prisms average 1" to 1 1/4" in length. This specimen was formerly in the collection of the Fersman Mineralogical Museum, Moscow, and has a museum label. Size: 2" wide X 2" tall X 1 1/4" thick. Order item MI-042 SOLD |

FLUORAPATITE on QUARTZ State of Minas Gerais, Brazil Many more than 100 translucent, very sparkly, light blue Fluorapatite crystals are completely covering two sides of the termination, and scattered over part of the back of the specimen (on the prism faces) of a single large Quartz crystal. A small amount of white bladed Albite Var. Cleavelandite is associated on the back/base of the Quartz crystal – no rock matrix. Very good cabinet size specimen for display! The Fluorapatite crystals are fluorescent light yellow-golden under SW UV, and weak yellow-golden under LW. Phos: none. The Albite is not fluorescent. Jim Clark collection. Specimen size: 4" tall, 3 3/4" wide, 2 5/8" thick (i.e., this is the size of the Quartz crystal) Order Item MI-043 SOLD |

The Cerro Prieto area is known for its past production of Gold in nugget form, and the occurrence is mentioned in “Minerals of Mexico”, W. Panczner, P. 214 (1983). Pricing is @ $30. / gram for items A. through E., and items F. through I. are priced at $28. / gram. Order Item MI-044, A. through I.

RHODOCHROSITE El Potosi Mine, Municipio de Aquiles Serdan, State of Chihuahua, Mexico Medium pink color botryoidal Rhodochrosite, with a micro crystalline surface, almost completely covers the top of the matrix. Kutnohorite has formed as a veinlet composed of compact, pinkish-gray acicular crystals sandwiched between two layers of a dark brown manganese oxide mineral, upon which the botryoidal Rhodochrosite was deposited. A thin vein of brassy, massive Pyrite is present at the base of the specimen. No rock matrix. This locality is mentioned in "Minerals of Mexico", W. Panczner, P. 328 (1987). Dr. Fred P. D’Esopo collection. Specimen size: 2 1/2" wide, 1 7/8" high, up to 1 1/2" thick. Order Item MI-1004 Price: $150. |
