Attractive and classic Yaogangxian specimen consisting of a large doubly-terminated Quarz crystal, cubic purple Fluorite, yellow/green Muscovite, and tan Scheelite crystals. It's nearly a floater with a small point of contact at the base, otherwise complete all around and undamaged.

Good coverage of yellow/orange dipyramidal Wulfenite crystals on a light colored matrix.

Single purple Topaz crystal from Ouro Preto. Complete all around and undamaged with glossy luster. Uncommon color! Ex. Jon Sigerman.

Cluster of clear Quartz crystals with a large Japan Law twin on one side. Long, slender clear Quartz crystals with inclusions of Sulfur and Muscovite. There are also unidentified white blebs and brown acicular crystals included within the Quartz. In good condtion with no significant damage,  all the main crystals are undamaged.  From the Chuck Trantham collection and comes with an old label from Alfredo Petrov showing a price of $160, and I offering it for less than Alfredo's old price.

A cluster of clear, sharply terminated Quartz crystals is host to several dark color Schorl Tourmaline crystals included within the center. The Schorl crystals are visible from both the front and back of the Quartz cluster. It comes with a very detailed Bob Trimingham label that notes an excellent provenance from some well-known collectors. No damage to any of the main crystals and only a minor amount of micro-chipping.

Undamaged cluster of yellow Smithsonite crystals on matrix. Crystals reach 2cm in size. A good example of Tsumeb Smithsonite, considered teh world's best, and no longer being found.

Cluster of dark red Pyrargyrite crystals. Main crystal is complete and 1.8cm wide.

Rich Pyrargyrite specimen with numerous clusters of well-defined crystals scattered throughout the sulfide matrix. Other species in association include Pyrite, Quartz, and Calcite. Reminds me of an ice cream cone studded with Pyrargyrite chocolate chips!

Large, solid radial mass of yellow Brucite on matrix. Superb, complete 'pinwheel' on matrix that displays wonderfully. This is an uncommon example well crystallized all around, characteristic of open pocket growth and not growth in tight, contacted seams as are most. Translucent, thick and sturdy. Undamaged.

Large, solid radial mass of yellow Brucite on a small speck of matrix. The specimen is solid Brucite well crystallized all around and undamaged. It's a 360 degree 'pinwheel' formation on a small amount of matrix. This example is nearly a floater because the matrix is partially covered by a thin layer of lighter colored Brucite. It is translucent, thick and sturdy, and undamaged.
