F-248  Fluorite on Microcline  $75

Erongo Mountain, Karibib, Erongo Region, Namibia

6.9 x 5.7 x 4.1 cm

A translucent, color-zoned crystal of Fluorite measuring 3.5 cm accented by many smaller crystals on a little bit of corroded Microcline.  I consider these Fluorite specimens every bit as interesting and desirable as the Beryl and Tourmaline specimens from Erongo.

F-229  Fluorite on Barite  SOLD

Liter's Quarry, Breckenridge County, Kentucky

10.6 x 6.1 x 2.6 cm

While Illinois is the undisputed king as far as Fluorite from the U.S. is concerned, its neighbor to the south has been known to produce the occasional specimen.  This specimen features cubes of light-purple-colored crystals of Fluorite measuring to 1 cm perched on a matrix of bladed crystals of Barite.  While seldom seen at the best of times, Fluorite specimens from Kentucky have always been eagerly sought out by collectors.  This specimen came labeled as being from the Irvington Quarry which is the former name of Liter's Quarry.

AD-155  Agate  $50

Patagonia, Argentina

7.7 x 3.9 x 2.9 cm

A vividly-colored Agate from Patagonia. This Agate exhibits a parallax which is sometimes referred to as winking. When a banded Agate forms with close alternating opaque and transparent bands, the light entering the Agate can cast an observable shadow from one opaque band onto the next. As the parallel bands change their perceived angle, the appearance of movement and perception of depth occur.

Kardzhali Oblast, Bulgaria

10.5 x 4.5 x 2.4 cm

A polished section of white and gray Agate surrounded by brown Chalcedony that has been partially included by green-colored Celadonite.  The locals call this material “Orpheus Agate”.  I don't know if the deposit is exhausted or not, just that it is getting very difficult to find this material these days.

This specimen hails from a location that is well known its phosphate minerals and superbly crystallized Rose Quartz.  This specimen consists of an etched (but complete) crystal of Microcline featuring a clear, sceptered crystal of lightly colored Citrine sprouting from its side.  Natural Citrine Quartz crystals are uncommon worldwide and even more so as scepters.  This specimen is complete all around with no damage.  This specimen was once in my collection and was part of several award winning competitive exhibits of Brazilian Minerals

Q-475  Quartz with Montmorillonite inclusions  $75

White Queen Mine, Pala, San Diego County, CA

6 x 3.5 x 4 cm

A classic Quartz from the pegmatites of northern San Diego County. In 1970's several pockets with Quartz crystals with pink & tan Montmorillonite inclusions were found at the White Queen Mine. Many of these crystals, especially the larger ones, were sawn in half & polished to better show these inclusions. What saved this one from being brutalized by saw and lap is the fact that a portion of this crystal had dissolved and re-crystallized leaving a cavernous indentation. The faces of this crystal that haven't been etched are glassy which is uncommon for this material. Examples of these crystals are rarely seen these days.
