Brilliant and quite exceptional crystalline Native Silver in white Calcite on matrix!
This is one of the finest Moroccan Silvers I've seen from Bou Azer. Not only is the crystalline structure
bright and lustrous, but it also sits atop the bright white Calcite which sits atop host matrix rock. I can't recall
seeing another on matrix Silver from this locality. The specimens I've seen in the past come with the Calcite
but not the hard rock matrix. The eye appeal of this specimen is superb with the transition from lustrous Silver
to white Calcite to gray matrix. Whoever did the trimming on this specimen did an excellent job. I love this piece!

Exceptional large cabinet plate of Amethyst crystals on a unique looking brown matrix!
Believe it or not, it was the matrix that first attracted my attention when I came across this very
impressive large plate at the show. It looked like the cracked clay bed of a dry river bottom and it
was covered with a sparkling druse. I've not another another matrix like it from Piedra Parada and
the large Amethyst crystals that sit atop are absolutely perfect and pristine. They are fully terminated
with gemmy interiors and a glowing purple coloration. The largest crystal is doubly terminated and lays
horizontally to the matrix. It measures 5.5 cm in length. The other Amethyst crystals vary in size and rise
vertically atop the dazzling surface. This is one of my favorites from the show. It's a superb display piece.

Sharp, lustrous crystals of Azurite with Malachite on Calcite covered matrix!
This is a tremendous old time classic from Zacatecas. It was formally in the famed Romero Collection
before being donated to the University of Arizona Mineral Museum. With so much attention paid to the
Milpillas specimens these days, the old classic Azurites from Mexico are being somewhat overlooked
and this is definately one that should be taken notice of. The surface of this plate is covered from one
end to the other by dozens of glassy-lustrous Azurite crystals. The crystals measure to 1.4 cm in size
and average around 1 cm in size. They display chisel-tip terminations and many are doubly terminated.
Surrounding the dark blue Azurite crystals are transparent Calcites and a small cluster of Malachite
ps after Azurite crystals to the far right. They all sit atop a matrix covered with smaller Calcites and
the specimen is in excellent condition overall, with most contacts being limited to the trimming edge.

Very rare! Aesthetic combination featuring Anhydrite blades on yellow Calcite crystals with Fluorite!
This is a rare specimen, the likes of which I haven't seen in many years. Very few were discovered
and they are almost impossible to find in the marketplace. This piece, as almost all that appear for sale,
is from an older collection. Matrix specimens with aesthetics and isolated crystal sprays like this one are
a true prize! This competition-level specimen is unique for its aesthetics, in that the 3-dimensional cluster
of Anhydrite, with crystals measuring to 10 cm, is balanced against a pedestal of Calcite crystals. It is from
the noted Mexican collection of Dr. Peter Megaw, who travels extensively in Mexico and specializes in
Mexican minerals. These blue Anhydrite blades in in excellent condition and perfectly fram the Calcites.

Amazing specimen of Silver pseudomorphing after Acanthite crystals!
This is a tremendous Silver pseudo and the first I have seen from the Rayas Mine. The Native Silver has
pseudomorphed the majority of the Acanthite and also appears as small wires atop the crystal surfaces.
The habit of the Acanthites is somewhat hoppered and this has been well preserved by the Native Silver.
Interestingly enough, there is also Calcite present in the center of the specimen and a small purple Fluorite.

Rare! Traslucent green octahedrons of Fluorite on white Quartz!
This is the first and only specimen of Fluorite I've seen from this rare locality near Austin in
the great state of Nevada. I know Austin as a famous locality for Silver minerals but this obscure
Fluorite find appeared in the marketplace a couple of decades ago and quickly disappeared. There
are over half a dozen octahedrons of grassy-green Fluorite here, with the largest of these measuring
right at 4.3 cm in size. They also exhibit a bluish-purple fluorescence under UV lighting. Overall the
