Opal - precious opal
Carbonera Mine, La Trinidad, Tequisquiapan Municipality
5.1 x 3 x 1.5 CM (small cabinet/ large miniature)
Unusual locality for this sort of opal that looks very Australian. The Carbonara mine in Mexico has produced mostly a reddish "Fire Opal" but small amounts of precious Opal with a milky white base have been found over the years. This piece has quite good fire with red, green, blue and some orange color flashes.
Sherlova Gora, Adun-Cholon Range, Nerchinsk, Chitinskaya Oblast
3.1 x 2.7 x 2.8 CM (small miniature/ large thumbnail (toenail))
A single transparent Russian Topaz with a very light blue hue. Nice but not perfect, there are contacts on the back and a few small edge nicks but still displays very well. Russian Topaz from Sherlova Gora is a classic, the area was producing Topaz back into the early 1700 era. This has better clarity than typical for the locale.
The Prase type Quartz from Serifos can be especially attractive and is a modern classic. This is a choice small cabinet specimen with good color, form and is in good condition, some chipping is seen on close inspection not visible at several angles but this keeps this price low. A ball of Hematite blades is a nice and rather uncommon addition. The locality still continues to produce some Quartz every few years but these have become quite hard to find at reasonable prices or in anything close to good condition.
Sceptered Quartz in excellent undamaged condition with the cap having no prism faces. The shaft of the scepter has several tiny Cumberland habit crystals arranged epitaxially, and which also have a yellow zoning. An attractive Quartz specimen of unusual habit from a find in 2018, this looks great from any side.
Epidote on Quartz
Green Monster Mountain, Prince of Wales Island, Prince of Wales Island
4.6 x 2.6 x 1.7 CM (miniature)
A choice tabular habit Epidote from the legendary finds at Green Monster Mountain in Alaska, USA. The Epidote is a complete textbook form crystal and quite lustrous. Deep green to brownish yellow hues nicely contrast with the clear colorless Quartz so the specimen stands out well. A fine specimen from the short list of great classic US locales.
Beryl v. Aquamarine, Schorl and Albite
Shigar, Skardu District, Baltistan
3.7 x 2.3 x 2.2 CM (small miniature/ large thumbnail (toenail))
A neat toenail of gem clear Beryl set on snow white Albite and glassy black Schorl Tourmaline. From recent finds at Shigar, this is a classic combination. The Schorl has a hoppered termination at one end and the Aquamarine is glass clear and perfect on all sides. An excellent specimen that could be trimmed to thumbnail size if desired but is fine as is.
San Luis Potosi,
2.1 X 1.6 x .8 CM (thumbnail)
A pair of perfect small Fluor Buergerite crystals are laying on contrasting matrix. From the type locale, this rare member of the Tourmaline group is only available from older pieces like this, none has been found for decades. No damage, a well composed thumbnail.
Red Cloud Mine, Silver District, Trigo Mts, La Paz County
3.3 x 3.2 x 3.1 CM (small miniature/ large thumbnail (toenail))
A nice pretty small miniature Red Cloud Wulfenite matrix with a free standing main crystal that is a deep red-orange. The standing crystal is damage free, this is an esthetic small piece that could be trimmed to fine thumbnail if wanted. From a small scale mining attempt in 2017. The matrix is not the crumbly sort and has many small Calcite crystals scattered as well.
