TUCTS-04 - This exquisite miniature specimen from Erongo features an aesthetic spray of gemmy aquamarine crystals perched on the horizon of the piece. Adding contrast of texture and color are several siderite crystals (appear to be pseudomorphs) and cream-colored feldspar.
DSK-04 - With a pleasing yellow color, several gemmy calcite crystals rest on a matrix of crystallized stibnite. The largest calcite crystal is twinned, and each of the calcites contains stibnite inclusions. Superbly lustrous and aesthetic!
DSK-07 - Far more transparent and lustrous than photos indicate, several smoky quartz prisms host rich orange, gemmy spessartine crystals on white microcline feldspar. The specimen has excellent balance and displays well.
DSK-01 - Boasting surprisingly sharp, vibrant pink ruby crystals on matrix, this fine miniature specimen is well-balanced and eye-catching. The color of the ruby varies strongly according to how it is lit...showing more of a red modifying hue in incandescent light.
TUCTS-01 - Grape purple cubes of inter-penetrating fluorite crystals surround a pair of very transparent quartz prisms along with yellow siderite and black muscovite in this very fine miniature. Both quartz crystals have lustrous faces, especially at the termination (highlighted in the picture to show form) and the larger crystal contains a phantom coated by siderite. Displays well from all angles. Mined 2013

MMT-702 - A study in contrasts, this small cabinet specimen boasts a smoky quartz crystal (6.8 cm) covered on all sides with transparent, rich orange spessartine crystals. The white matrix provides an ideal setting. The quartz crystals are transparent, and the specimen is in ideal condition.
Fluorite - $1250 Shangbao Mine, Hunan Prov., China
7.2 x 6.1 x 3.7 cm
MMT-704 - The glassy faces of this lovely cuboctahedral fluorite crystals allow you to peer into the crystal to admire the interplay of purple and pale green inside. The crystal is pristine and quite transparent. Note the small cubic crystal that accompanies the larger, isolated crystal.
MMT-705 - In this sculptural piece, several hexagonal apatite crystals perch on the horizon of an albite matrix. The basal faces are glassy and the crystals possess a dark core with a forest green translucent layer on the outside.

Better in person...you won't be disappointed.
TYP-002 - A vivid, eye-catching combination piece features several different species hosted on a stalactitic matrix, including needles of blue-green rosasite, colorless hemimorphite, and pseudo-octagonal adamite.

NY2-330 - Razor sharp, superbly lustrous crystals of arsenopyrite (to 3.4 cm) are accompanied by numerous quartz crystals all on a tan matrix of what appears to be cookeite. Photos do not correctly reveal the quality of these arsenopyrite crystals...they are just spectacular and aesthetic with their stepped growth patterns and interlocking arrangement.
NY4-500 - A surprisingly aesthetic silver pseudomorph, this specimen features a dramatic spray of thick silver needles that preserve the form of the dyscrasite that they have replaced. In addition, the matrix contains a high silver content with an attractive silver streak drawing the eye toward the silver crystals on top.

NY2-325 - Perhaps my favorite piece right now from the new update is this gorgeous cabinet specimen from Greece that simply glitters with thousands of drusy quartz crystals that cover the surface of the specimen. The pink coloration is from rhodochrosite which is included within the quartz in selective areas. On the left of the specimen is a radiating cluster of quartz prisms that bring a nice size contrast and another shape in addition to the rhombs of calcite(?) on the right side of the piece. Well-balanced and beautiful!
MMB-893 - With a silky luster and a pleasant pink color, this cobaltian smithsonite would make a great addition to a Tsumeb suite (or worldwide collection). The back of the specimen is likewise covered in crystallized smithsonite. A galena crystal crowned with pink crystals displays a metallic shimmer. Great condition.
MMT-707 - A thick (3.8 cm) band of rose quartz rises from the top of a smoky quartz crystal in this lovely small cabinet specimen. While not as transparent as the specimen above, the pink color is slightly more saturated. This piece also features a transparent gem on the horizon of the specimen.

Sarbaiskoe deposit, Kostanay Prov., Kazakhstan
6.6 x 5.7 x 3.5 cm
MMB-795 - A cluster of golden-yellow, twinned calcite crystals rests on a matrix coated with small, pale yellow calcites. The transparency of the specimen is quite nice...better than photos can show. There are no cleaved edges. Each crystal is complete and wonderfully formed with curving lines, selective frosting and light striations.
MMB-847 - Dendritic copper crystals extend from a matrix of crystallized calcite in this small cabinet specimen from Tsumeb. Natural copper crystals from Tsumeb are quite rare, and this is a fine combination piece for any Tsumeb suite or worldwide collection.
