Q-524  capped Quartz  SOLD

Holder Road, Trowutta, Arthur River District, Circular Head Municipality, Tasmania, Australia

6.5 x 2.4 x 3.2 cm

Here we have an example of an unusual variety of Quartz. Capped Quartz crystals are comprised of loosely connected or easily separable parts that correspond to different growth phases. This is caused by the deposition of thin continuous layers of clay minerals on the crystal during growth. The typical result is a crystal tip that can be taken off of the crystal and that is shaped like a little cap.

Squaretop Mountain, Kaimkillenbun, Dalby, Western Downs Region, Queensland, Australia

13.8 x 12.2 x 7.4 cm

A nicely shaped, 3-dimensional example of Hyalite Opal. The way the Opal formed on this specimen reminds me of bubbling water bursting forth from the Basalt matrix. The squaretop Mountain specimens hold up against other Hyalites from classic localities like Valec in the Czech Republic. This specimen exhibits a good apple-green fluorescence.

4.8 x 4.4 x 3 cm

A well-formed, earth-colored nodule of the uncommon phosphate mineral, Diadochite. Diadochite is a secondary mineral most often occurring in gossans and coal deposits as the result of sulfate-rich solutions reacting with earlier phosphates; it also occurs in secondary phosphate assemblages in granitic pegmatites and cave deposits.

C-295  Colemanite  SOLD

Pacific Mine, Calico Mountains, San Bernardino County, CA

A largish specimen showing a vug of off-white, somewhat rounded blocky Colemanite crystals up to 4 cm, some of which appear to be transparent internally. This is an old-time specimen and material such as this is rarely seen today. The Colemanite crystals fluoresce a respectable lemon-yellow under LWUV and a creamy-yellow and orange under SWUV. The Pacific Mine was the first underground mining of Colemanite in the USA. The deposit was discovered in 1882 and first production was in 1884.

A double terminated Smoky Quartz crystal from the Sawtooth Mountains of Idaho. This specimen is a complete all-around floater with only several very miniscule imperfections to its terminations.

No more of these spectacular Rose Quartz crystals from Afghanistan have been found since. This specimen features a pseudocubic crystal of Smoky Quartz that serves a a host for a fan-like assemblage of nearly transparent crystals of Rose Quartz. This specimen is comparable to the old-time Brazilian specimens.

Q-523  Citrine with Indicolite inclusions  SOLD

João Velho Mine, Jenipapo District, Itinga, Minas Gerais, Brazil

7.6 x 6 x 3.8 cm

A very clear crystal of Citrine has has been included by Indicolite Tourmaline. This specimen is complete all-around and has no damage. Quartz crystals included by blue Tourmaline from this location have been available for around 20 years but few of them are Citrine. Natural Citrine Quartz crystals are uncommon worldwide and are almost never found associated with minerals except for Feldspar and other varieties of Quartz. These Citrine crystals from João Velho are the only examples of Citrine that has been included by another mineral that I am aware of.

Ex R. Rizzo

Sapo Mine, Ferruginha, Conselheiro Pena, Minas Gerais, Brazil

12.4 x 4.5 x 2.8 cm

A long and well-formed example of Muscovite replacing Tourmaline. The Muscovite has a nice metallic hue and a decent lustre. These specimens were from a find made in 2010 that was first available in 2011 at the Tucson show causing a minor stir. I was fortunate enough to get the first look at these specimens and took home a few, passing on the one matrix specimen from the lot that was later featured in The Mineralogical Record's 2011 Tucson Show report. This is the last one of these that I have and for a time was a part of my award winning Brazilian collection.

Ex John P. Frey

Himalaya Mine, Gem Hill, Mesa Grande District, San Diego County, CA

8.3 x 4.2 x 3.6 cm

A very lustrous, etched & tapered Elbaite crystal from a find made in the 1980's dubbed the “cityscape pocket”. This specimen grades in color from green at the bottom to a hot pink-colored termination. The upper 80% of the specimen is clear and the center portion of the specimen exhibits a grass-green color with minimal backlighting. A superb example of this material and one of the largest that I have seen from this unusual find.
