Dolomite- Penetration twins, gemmy crystals
stock #AX-19-153
Cantera Nueva, Eugui
Navarra, Spain
7.1 x 6.3 x 3 CM (cabinet)
price: $420
Worldwide mix summer

A fine transparent cluster of Dolomite crystals from the classic Spanish locality of Eugui, Navarre. An uncommon matrix piece, the crystals are up to 4 CM in diameter and very sharp, undamaged. Dolomite is a very common mineral and crystals are not rare at all, but sharp, gem clear Rhombs like this are really only found at this one locality and they are very rare in such quality. Some minor dark zoning is seen but overall these are white to colorless and mostly transparent. The penetration twinning is textbook sharp and clear, an excellent piece found in 1998.

Pyrrhotite with Siderite
stock #AX-27-204
Morro Velha Mine, Nova Lima, Iron Quadrangle
Minas Gerais, Brazil
4.5 x 3.8 x 1.3 CM (miniature)
price: $390
Worldwide mix summer

An exceptionally fine, bright metallic hexagon of Pyrrhotite dusted with a few small Siderite crystals. Ex Larry Conklin, Terry Szenics collection. In excellent condition, this is an fairly old vintage Brazilian specimen from Morro Velha, and is the sharpest with the best luster I have seen. Morro Velha has the distinction of being the longest running Gold mine in the world, it is well known for good Siderite specimens but Pyrrhotites of any size are rare. This is a nice Pyrrhotite from anyplace but incredible for Brazil. In excellent condition.

Beryl var. Emerald on Quartz
stock #18.1-053
Mina El Toro, Chivor Municipio de Chivor
Boyaca, Colombia
5.4 X 4.3 x 3.5 CM (small cabinet/ large miniature)
price: $1200
Worldwide mix summer

Large translucent Emerald crystals protruding from a vuggy Quartz matrix. From a little known mine (Mina El Toro) that is in the Chivor district of Colombia, this is an attractive specimen with rich color. The main crystal is 4.3 CM long and the termination is quite choice. Quartz is a rare matrix for Colombian Emeralds since most are found in Calcite veins. On close inspection the Quartz shows several crystal faces that are distorted and bent, a very odd matrix. Displays well obviously not top facet grade but not priced at 20,000 per carat either. The form and color make this a very attractive specimen that is a fine addition to any suite of Beryls, Colombian minerals or just a collection of nice esthetic pieces.

Wulfenite
stock #15.1-541
Chah Milleh Mine, Anarak Dist., Nain Co.
Esfahan Province, Iran
3.3 x 1.9 x 1.3 CM (thumbnail)
price: $95
Worldwide mix summer

A cute thumbnail of the orange-red Wulfenites from the 2015 find in Iran. These crystals are remarkably similar to Red Cloud mine Wulfenites but the matrix is a little more complex and has many tiny Wulfenites with different habits. The main Wulfenite is contacted/ chipped on its bottom edge so this is not for a perfectionist but the contact is where this would sit and so is not visible under most display conditions. The price reflects this. Good color, transparency and sharpness.

Wulfenite with Mimetite
stock #18.1-278
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
2.2 x 1.4 x .9 CM (thumbnail)
price: $160
Worldwide mix summer

A sharp windowpane type Wulfunite crystal on matrix that is dusted with tiny Calcite crystals. In fine condition despite the delicay of the piece, the crystal has a more red color seen from the back and a more yellow-orange from the front.

Quartz with Rutile and Chlorite
stock #18.1-109
Manihar Valley Kuilu District
Himachal Pradesh, India
9.8 x 5.4 x 4.2 CM (cabinet)
price: $350
Worldwide mix summer

A remarkable Alpine type quartz from the amazing new finds in the Manihar Valley. The clarity of this Quartz in person looks like a fine Swiss specimen, the small areas of Chlorite and a few sprays of Rutile needles are also distinctive. A few of the prisms in this cluster are doubly terminated, and all are clear enough to see through to see the chlorite matrix on the back side. A very sculptural arrangement, there is no damage here just a few contacts and the whole is a very esthetic cluster.

Phenakite - Untwinned crystals on matrix
stock #18.1-157
Phenakite mine, Khetchel Village, Molo Quarter, Momeik Township, Kyaukme
Shan State, Myanmar (Burma)
4.6 x 3.2 x 2.7 CM (miniature)
price: $280
Worldwide mix summer

Sharp glassy crystals of Phenakite perched on Microcline and Quartz. Most Myanmar Phenakite is twinned, this is the more rare untwinned form of blocky crystals which are in fine condition. Matrix examples are also quite uncommon, most specimens are loose single six sided prisms. A good value for a choice, uncommon type Phenakite.

Sphalerite -gemmy prismatic
stock #18.1-275
ZCA Mine number 4, Balmat, Balmat-Edwards District, St. Lawrence Co.
New York, United States
1.6 x 1. x 1 CM (thumbnail)
price: $200
Worldwide mix summer

Small thumbnail of sharp, glassy transparent crystals of Sphalerite from New York. Textbook forms and with bright luster, the crystals are in fine condition. A modern northeastern US classic locale, these Sphalerites are choice little gems.
