Isolated, gemmy single Sulfur crystals suspended in light, airy Aragonite. The specimen formed as a floater in the center of a pocket and is different in style than the usual crystals on solid Aragonite that are collected from pocket walls. This was the most aesthetic example (in my opinion) from the find. Crystals reach 1.3cm in diameter and are present on both sides.

Well dispersed, isolated twinned Bournonite crystals to 4mm all over a Pyrite rich matrix. The Chichibu mine is hundreds of years old, and produced the first copper mined in Japan, in the year 707 C.E. A historic specimen in great condition.

Single 'cogwheel' of Bournonite with Quartz crystals attached to one side. Undamaged, historic and classic specimen. This was in the Jim Poteete collection and comes with his engraved plastic display plaque.

Tabular Wulfenite crystals on a matrix coated by tiny Descloizite crystals. Highly aesthetic, undamaged specimen.

Dense coverage of exceptionally glassy, gemmy Rhodochrosite crystals with a nice balance of accenting Quartz crystals. Undamaged, superb example.

Colorless Apophyllite that has overgrown another tan colored Zeolite to create a 'disco ball' formation. I remeber these were available once about 5-6 years ago and I've not seen them since, this one released recently from a private collection. Sparkly and undamaged.

Complete 'citrus' orange Spessartine crystal from old finds in Tanzania. These were mostly found as partial or damaged crystals with perfect complete crystals such as this much less common. Equant form with very minimal edge wear, otherwise no damage. There are a few small areas of black Braunite inclusions, otherwise it's nothing but gemmy orange. These were often cut up into spectacular gemstones, and this one could cut a number of small gems.

Complete, steeply terminated crystal of Dravite. High quality crystal that is undamaged and gem quality top to bottom.

Formation of large, tooth-like Prehnite crystals over a small amount of Graphite. Beautiful rosette-like formation that is complete all around. Slight chipping to some crystals but in good condition overall with good color and translucency.

Radial clusters of bright lemon yellow Prehnite grown atop the flat surface of a partial Quartz crystal. Lustrous Prehnite with great color and the only one I have with Prehnite on a Quartz crystal.

Rare polyhedral Agate from Brazil, famous for the their angular geometric shapes rather than the more typical agate form of rounded nodules. How these formed is still debated but the general consensus is that they are the result of agate forming in the space between preexisting crystals of other minerals such as gypsum, barite, or anhydrite. These were found in the 1970s and the locality that used to produce them is now under water due to the construction of a dam. This is a good large example in excellent condition.
