Fluorite on Calcite Fluorite on Calcite Fluorite on Calcite Fluorite on Calcite Fluorite on Calcite

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.

Specimen of solid white, translucent crystaline Cryolite from Greenland. Cryolite is a rare sodium aluminum fluoride mineral best known from this locality. It's name derives from the Greek words for 'frost stone' because it resembles ice.

TL118 - Brucite   $2,400  available

Killa Saifullah, Balochistan, Pakistan
Small Cabinet - 9 x 7 x 6 cm

Brucite Brucite Brucite Brucite Brucite

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

Turquoise after Beryl or Apatite Turquoise after Beryl or Apatite Turquoise after Beryl or Apatite Turquoise after Beryl or Apatite

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.

TL124 - Veszelyite   $1,800  available

Dongchuan, Kunming, Yunnan, China
Thumbnail - 3 x 2 x 1.3 cm



(click on an image to enlarge)

Veszelyite Veszelyite Veszelyite Veszelyite Veszelyite

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



(click on an image to enlarge)

Spessartine Spessartine Spessartine Spessartine

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).
