A super specimen of a pristine, 1.9 cm, translucent, yellow fluorite ball aesthetically set on crust of sparkly quartz crystals. This piece comes from the unique find at the Mahodari Quarry a couple of years ago. 5.2 x 5.1 x 1.9 cm
A BEAUTIFUL Sweet Home rhodochrosite specimen with very gemmy and lustrous, red rhodo rhombs to 1.2 cm on needle quartz. The supply of these is drying up rapidly, with the recent closing of the mine. 3.7 x 2.5 x 1.8 cm
A VERY SHOWY, EXCELLENT and very nearly pristine Colorado specimen from the famous Idarado Mine. A sharp, CABINET-SIZED quartz crystal is coated with snow-white drusy quartz. The sidecar crystals add character to this fine piece, which has only one broken sidecar crystal on the backside. Ex Ed Ruggiero Collection, who purchased this piece in November, 1975. MUCH BETTER IN PERSON, as a Colorado collector will know. 11.3 x 5.7 x 5.1 cm
A showy and excellent Mexican specimen of botryoidal malachite in a sparkly, quartz-lined vug in matrix from the famous El Cobre Mine of Zacatecas. 7.2 x 5.3 x 4.3 cm
A showy specimen of light pink rhodo rhombs to 1.0 cm on sparkly quartz from a VERY UNCOMMON Colorado locality, the Daniel Bonanza Mine in Ouray County. Some of the rhodos are partially overgrown by quartz. 3.8 x 3.3 x 2.8 cm
A beautiful, sharp and lustrous bixbyite crystal nicely accentuated with quartz crystals from Utah. No damage and complete all-around. 1.1 x 0.9 x 0.8 cm
An EXCELLENT and aesthetic plate with nicely isolated, highly lustrous, very dark blue lazulite crystals to 1.0 cm and surrounded by amber, GEM siderite crystals and glassy, water-clear quartz needles on matrix from the famous Rapid Creek locality in the Yukon. This is VERY CHOICE, PRISTINE material with multiple display possibilities. Ex Marty Lewadny Collection of Winnipeg, Canada. 8.5 x 5.0 x 1.5 cm
A beautiful, undamaged cluster of very glassy, light purple amethyst crystals on matrix from the recent finds at Boekenhoutshoek, South Africa. Ex Lewadny Collection. MUCH, MUCH BETTER IN PERSOn. The very high lustre confounded the camera. 5.5 x 3.8 x 2.7 cm
An exceedingly aesthetic specimen of sharp scheelite crystals on a stack of quartz crystals capped by a gemmy, doubly-terminated one. One one side of the stack of quartz crystals you can see an arsenopyrite crystal that the quartz has grown around. The bottom side is the contact, where you can see that the arsenopyrite is intergrown with chalcopyrite. The scheelites are the characteristic color for the Yaogangxian, a sort of caramel-grey. 8.5 x 6.7 x 5.7 cm
A beautifully-formed, 4-cm crystal of pyrrhotite, with a dark bronze luster, on a bed of quartz crystals. You can see some tiny chalcopyrites on its surface. This specimen has wonderful overall form, a really classic look for a classic Dalnegorsk mineral. This specimen was mined in 1998. 6.2 x 5.8 x 2.9 cm
This is a fine "Thunder Bay"-style amethyst with hematite inclusions from a lesser-known locality. It has the same beautiful mix of purple and rust tones that make these so popular with collectors. 5.5 x 3.5 x 3.3 cm
The quartz crystals in this cluster, sharp and lustrous, contain inclusions of montmorillonite (Hydrated Sodium Calcium Aluminum Magnesium Silicate Hydroxide), giving them a creamy and very slightly pinkish tone. This is an old piece from the White Queen Mine. The crystals show a fine glassy luster. 5.9 x 4.5 x 2.7 cm
This is an intact vug or geode of gorgeous, sparkly dove-grey, quartz-covered stalactites. These stalactites formed through deposition within the vug, and then were decorated with a final generation of sparkly quartz microcrystals. From the noted collection of Paul Jung, recently dispersed at the Denver Show. 10.6 x 6.5 x 4.7 cm
