TL115 - Fluorite on Calcite $4,500 available
Huanggang Mine, Inner Mongolia, China
Small Cabinet - 8 x 5 x 4 cm
Three octahedral pink Fluorite crystals associated with platy white Calcite crystals. The Fluorite crystals are translucent pink with areas of green Byssolite inclusions and reach 3.5cm wide. This was purchased directly at the mine by a friend in China years ago, shipped to me, and held in my collection ever since. It was one of only a few available that had the association of the white Calcite crystals. In addition to the Calcite, the backside has two clusters of a metallic silver-colored mineral, possibly Lollingite. Well crystallized all around and undamaged (a floater). Ex. Mike Keim.
TL116 - Tourmaline $150 available
Cryo-Genie Mine, Warner Springs, San Diego Co., California, USA
Thumbnail - 2.6 x 1 x 1 cm
Bi-color pink and green Tourmaline crystal. The crystal is terminated on the green end and has many smaller Tourmaline crystals attached.
TL117 - Cryolite $80 available
Ivigtut Cryolite Deposit, Arsuk Fjord, Greenland
Small Cabinet - 5.3 x 4 x 3 cm
TL118 - Brucite $2,400 available
Killa Saifullah, Balochistan, Pakistan
Small Cabinet - 9 x 7 x 6 cm
Coral-like growth of bright lemon yellow Brucite crystals from Pakistan. An artistic, sculptural formation with multiple pearly clusters of Brucite on a small amount of matrix. The alternating stacked clusters of Brucite and contrasting colors of pearly white and lemon yellow create a striking specimen. Most Brucite from this locality grew in thin seams, this one is more 3-dimensional and robust than most. These new Brucite from Pakistan are world's best for the species and this is a fine example. Acquired from Irv Brown and held in my collection for years. Ex. Mike Keim.
TL119 - Turquoise after Beryl or Apatite sold
Apache Canyon Mines, Turquoise Mountain, Halloran Springs District, San Bernardino County, California, USA
Thumbnail - 2.8 x 2.7 x 2.6 cm
Stunning and large Beryl or Apatite crystal that pseudomorphed to Turquoise. The pseudomorph forms a prismatic hexagonal prism 2.1cm wide and 2.5cm tall. This is an excellent example for the locality as most are much smaller, not as sharp, or are partial crystals (these are brittle on most were destroyed in the removal process); in fact this is the best one I've ever seen. This was acquired from the Bob Reynolds collection. Bob was the former curator for the San Bernardino Co. museum and had many top/best of California specimens in his collection. The following is quoted from Mindat: 'Host rock is Teutonia quartz monazite (Beckerman, 1982). Late turquoise replacement of miarolitic cavities resulted in turquoise pseudomorphs after the following minerals: quartz, muscovite, beryl, microcline, apatite as well unconfirmed orthorhombic pseudomorphs labeled as after barite. Chesterman at the Ca. Div. of Mines and Geology confirmed turquoise pseudomorphs after beryl based on morphology, trace beryl remnants and in situ beryl nearby. (Nazelrod, pers. comm.)'. Ex. Bob Reynolds, Mike Keim collections.
TL120 - Silver sold
Elura Mine, Cobar, NSW, Australia
Thumbnail - 2.4 x 0.5 x 0.3 cm
Fine quality thumbnail-sized Silver specimen from old finds at the Elura Mine (likely the 1980s). Elongated spinel-twinned crystal that resembles a feather.
TL121 - Magnesioaxinite with Garnet $180 available
Taylorsville, Plumas Co., California, USA
Thumbnail - 2.4 x 2.0 x 1.5 cm
TL122 - Smokey Quartz sold
Minas Gerais, Brazil
Large Cabinet - 17 x 2.2 x 1.8 cm
Elongated, light smokey Quartz crystal with outstanding transparency - nearly flawless top to bottom. Perfectly terminated with very minor edge wear or imperfections along one edge, but essentially undamaged.
TL123 - Clinozoisite $2,500 available
Tormiq Valley, Skardu, Pakistan
Cabinet - 12.5 x 3 x 2 cm
Especially long, single Clinozoisite crystal from Tormiq. This is exceptional not only for it's size, but also for being a floater well crystallized all around and undamaged (even all the sidecar crystals are perfect!). Highly transparent. Ex. Mike Keim.
TL124 - Veszelyite $1,800 available
Dongchuan, Kunming, Yunnan, China
Thumbnail - 3 x 2 x 1.3 cm
Large, isolated single Veszelyite crystal on matrix. The crystal is 1.2cm long, which is larger than most and uncommon for being a single crystal (many were aggregates and clusters). Beautiful, richly colored crystal of this rare species from a July 2020 find at an old Zinc mine, one I kept in my collection for years. Veszelyite is a rare phosphate mineral only found in a few places worldwide as collectable mineral specimens. Ex. Mike Keim. .
TL125 - Spessartine $650 available
Nani, Loliondo, Arusha Region, Tanzania
Thumbnail - 3 x 3 x 2.5 cm
Mostly complete orange Spessartine with good translucency and areas of internal transparency. This is a crystal I put aside years ago for it's potential for faceting. I have cut some of them before with great results, yielding some beautiful large gemstones. I'm not a gem cutter and can't estimate what this might cut, but I will say the ones I have cut yielded more than I would have expected. Some areas of black inclusions but many areas of gem, bright citrus orange. Weighs 195 carats (a cursory web search shows these gems selling for $250-$1000 per carat).
TL126 - Spessartine $450 available
Nani, Loliondo, Arusha Region, Tanzania
Thumbnail - 2.6 x 2 x 2 cm
Partial orange Spessartine with good translucency and large areas of internal transparency. This is a crystal I put aside years ago for it's potential for faceting. I have cut some of them before with great results, yielding some beautiful large gemstones. I'm not a gem cutter and can't estimate what this might cut, but I will say the ones I have cut yielded more than I would have expected. Areas of gem, bright citrus orange. Weighs 95 carats (a cursory web search shows these gems selling for $250-$1000 per carat).
