Ridge top prospect is a small prospect on the top of Coyote Ridge, about
half way between the northern edge of the tungsten skarn area and the
southern edge of the tungsten skarn area, it is on the west center side of
Coyote Ridge. The matrix is a lighter color than the Merrill prospect,
and is frequently infused with small blebs of scheelite and sometimes as
crude crystals with the garnet. In this piece there is a nice
subhedral scheelite crystal on the top edge. These were rare in this
occurrence. There is another much smaller crystal on the lower

Dara-e-Pech pegmatite field, Dara-e-Pech district, Kunar, Afghanistan.
3.5 x 5.5 cm $500.00 The finest examples of Beryllonite
are those from Afghanistan. This rare sodium beryllium phosphate is often
found in smaller, nondescript specimens from various other pegmatite
localities around the world, but the specimens from Afghanistan are
incredibly well-formed, large and beautiful. This piece is a good-sized,
sharp, well-formed, euhedral, pseudo-hexagonal (monoclinic) crystal group of
Beryllonite showing the typical heavily striated prism edges, free of
matrix. The piece is actually a complete "floater" with no damage or point
of attachment anywhere. This piece dates back to the mid to late 1990s, when
some of the best examples of the material came out of Afghanistan.
Specimens are virtually not available for sale these days. One dealer

A couple of pieces are showing the soda straw structure of stalactites,
with a hole down the middle that you can blow through.
This one was so loosely attached to the ceiling, that when I touched it,
it fell to the floor of the water course, so it has some minor dings to the
tips of some of the crystals.

Jack (Ruby) mine, Imlay district, Pershing county, Nevada. 3
x 4 x 7 cm. 106g. $15.00 An old, obscure
mercury mine, I visited in 1983, and found at the end of one adit, an old
water course that was filled with cave type calcite, including many
helictites, as well as crystalline
calcite. The calcite shows two generations, the first as a yellowish
core, visible on some pieces, followed by brilliant, clear, gemmy calcite in
various forms and crystals. Some of the pieces show what appears to be
a "faden" thread in which the calcite crystals formed in both directions.

This one was found on the floor of the water course. There is no
clear point of attachment, Although the right end in this photo looks
likely, as it has a small hole in it. Several little calcite growths,
not sure I'd call them helictites, have grown over the pale yellow basal
material.

This one is a little different, as doesn't have the "sharks tooth"
crystals typical of the calcite from the floor of the water course.
These are more rounded, and trying to be somewhat rhombohedra, they were
from the side of the water course.

From the back of the water course were these somewhat duller, more satin
like luster, highly modified scalenohedra. I only collected a
few of these, as the luster is not as bright as the ones from the other
areas of the water course.
