JC6252. Djurleite. Dallas Gem mine (Benitoite mine) San Benito county, California. 7 x 11.5 cm 270g. $100.00. One of the rarer minerals from the benitoite mine. This one has a myriad of small crystals scattered all over it, and one unusually large one in the left center area that measures 7mm long. It is a flat lying, somewhat triangular shaped crystal. I show two closer views below, each one getting closer to the large crystal. Another larger crystal is just barely showing above the natrolite to the immediate right of this crystal. I wasn't sure I wanted to expose it, for fear of losing the larger crystal next to it. |

JC6254. Andradite. Paymaster Canyon, Gillis Range, Mineral county, Nevada. 5 x 5 cm 89g. $15.00. A 2 cm yellow green crystal with several partial crystals with a matrix of chalcedony and quartz. |
|
|
JC6256. Massicot, cerussite, and ? Shoshone mine, Shoshone, Inyo county, California. 4.5 x 6.5 cm 215g. $25.00. Yellow massicot with massive cerussite and other lead oxides. A small cerussite crystal is located on the top right edge of the specimen. A close up view of the cerussite is shown below. Collected about 1970. |

JC6257. Anglesite nodule. Darwin mine, Darwin, Darwin district, Inyo county, California. 4.5 x 6 cm 168g. $20.00. This is the sawn face of the nodule. These used to be found occasionally in the oxide zone. Miners called them lead potatoes. There are probably other lead oxides mixed in. Sometimes these would have an un-oxidized galena core, which this one has, and it is shown in the photo below, which is the back side of the specimen. |

JC6258. Anglesite nodule. Darwin mine, Darwin, Darwin district, Inyo county, California. 4.5 x 6 cm 364g. $25.00. This is the sawn face of the nodule. These used to be found occasionally in the oxide zone. Miners called them lead potatos. There are probably other lead oxides mixed in. Sometimes chlorargyrite is also present, but it would have to be x-rayed to determine that. The greenish outer layer may be chlorargyrite. |

JC6299. Pyrite, quartz, siderite? Shangbao mine, Leiyang, Hunan province, China. 6 x 9 cm 614g. $75.00. Small cubes of bright pyrite interspersed with quartz crystals and a partial crystal of what appears to be siderite. Fairly free of much damage, unusual for these specimens. Three views are shown. |

JC6106. Malachite pseuodo azurite, azurite. Tsumeb mine, Tsumeb, Namibia. 6 x 7 cm $200.00. Main crystal is 6 cm in size. A smaller crystal is offset on the right hand edge. Ex Konrad Olf collection, Idar-Oberstein, Germany. Collected in the 1940's. |
|
|
JC6106. Reverse. This might be a better display side, as the shape of the replaced azurite crystal is quite distinct. |
|
|
JC6358. Malachite pseudo azurite, azurite. Tsumeb mine, Tsumeb, Namibia. 6 x 8.5 cm 266g. $75.00. A 6 cm malachite mostly replacing azurite, with some unreplaced azurite also present. From the upper oxide zone. Ex Konrad Olf collection, Idar-Oberstein, Germany. Collected in the 1940's. |
|
|
JC6359. Malachite pseudo azurite, azurite. Tsumeb mine, Tsumeb, Namibia. 4 x 8.5 cm 242g. $40.00. A very crude azurite crystal nearly completely replaced by malachite. From the upper oxide zone. Collected in the 1940's. |
|
|
JC6361. Azurite, malachite. Tsumeb mine, Tsumeb, Namibia. 4.5 x 5 cm 65g. $20.00. From the upper oxide zone. Collected in the 1940's. |
|
|
JC6362. Azurite, malachite, hydrocerussite? Tsumeb mine, Tsumeb, Namibia. 3.5 x 5 cm 64g. $20.00. Crudely crystallized azurite, with malachite. The white mineral has the crystal form of cerussite, but appears to be replaced by hydrocerussite. Could use x-ray verification. From the upper oxidation zone. Collected in the 1940's. |
|
|
JC6363. Azurite, malachite. Tsumeb mine, Tsumeb, Namibia. 4.3 x 4.5 cm 60g. $15.00. Bright blue, crudely formed azurite crystals with malachite pseudo after crudely crystallized azurite. From the upper oxidation zone. Collected in the 1940's. |
|
|
JC6364. Azurite, malachite. Tsumeb mine, Tsumeb, Namibia. 3 x 3.5 cm 23g. $10.00. Bright blue, azurite with malachite pseudo after crudely crystallized azurite. From the upper oxidation zone. Collected in the 1940's. |

JC6370. Grossular. Jeffry mine, Asbestos, Shipton township, Richmond county, Quebec. 2.5 x 5.5 cm 18g. $35.00. What is interesting about this one is the joined together main crystal. It looks like twinning, but I have not heard of garnet twinning in this manner, more likely it is just a joining of two crystals. |
