6.9 x 5.3 x 4.5 cm. This is really quite a superb combination piece, featuring a perfect 4 cm doubly-terminated green Apophyllite. Both tips are extraordinary and complete. The luster and the gemminess are excellent. There are also numerous light-pink Stilbite blades with gorgeous pearly luster – many are doubly-terminated themselves. These crystals primarily rest on two masses of very attractive drusy quartz, which themselves rest on the matrix. When you start looking at it closely, you realize that those "masses" of quartz are in fact flattened calcite rhombohedra, completely replaced by the quartz.
9.4 x 6.9 x 4.2 cm. A visually dramatic piece featuring a 4 cm salmon/red-colored Heulandite that has great luster and superb gemminess for the species. The color is unusually intense. The large Heulandite rests in a forest of very fine Chalcedony "straws," which helps create the incredible aesthetics of the piece. The several smaller Heulandites add accents to the piece. Truly wonderful specimen with unique aesthetics.
7 x 6.3 x 4.5 cm. These famous finds of the 1970s produced some superb Hubnerites, such as this specimen. The 4.5 cm Hubnerite is stunning and classic, with its superb luster and sub-parallel bladed growth making for a dramatic termination. The Quartz crystals are excellent – well terminated with a lovely white frosting. Ex. Marty Lewadny Collection.
23.7 x 15.7 x 13.8 cm. A fine large cabinet specimen from the less well-known Elizabeth R. Mine of San Diego County. An 8.8 cm, highly lustrous, striated, dark tourmaline crystal is attached to a termination face of a huge, translucent, glassy smoky quartz crystal. The tourmaline and the contacted, but undamaged, back of the smoky quartz are partially covered with feldspar overlay. This is seldom available, large material and only available from insider collections. Older material from the Chuck Houser Collection and according to his label, was collected in 1984. It then went to the Bill Larson/Pala Intl Collection. Weighs 8.4 pounds or 3.8 kilograms.
8.9 x 5.2 x 4.4 cm. An aesthetic and beautiful amethyst specimen. Gorgeous, glassy, translucent to transparent, purple crystals of amethyst stand side by side. The large crystal is 3.4 cm. The crystals really sparkle and are called "cactus quartz" for their form. The terminations are isolated, while the bodies have a prickly, "cactus" look with an overgrowth of smaller crystals. This is the true source for the amethystine quartz crystals (aka "cactus quartz" and "spirit quartz") erroneously marketed as being from the Magaliesberg Range. A lovely example with great color and the iron oxide inclusions are a very nice accent. Complete-all-around and very nearly pristine. Ex. Wes Parker Collection.
11.4 x 8.4 x 8.0 cm. A striking cabinet amethyst specimen. Gorgeous, glassy, translucent to transparent, purple crystals of amethyst stand side by side on the plate. The large crystal really dominates this piece. The crystals really sparkle and are called "cactus quartz" for their form. The terminations are isolated, while the bodies have a prickly, "cactus" look with an overgrowth of smaller crystals. This is the true source for the amethystine quartz crystals (aka "cactus quartz" and "spirit quartz") erroneously marketed as being from the Magaliesberg Range. A lovely example with great color and the darker purple termination areas are a super accent. Complete-all-around and very nearly pristine. Ex. Wes Parker Collection. This specimen is distinctively different from the usual "cactus quartz" from this locale.
16.8 x 13.2 x 5.8 cm. A fine large cabinet amethyst specimen. Gorgeous, glassy, translucent to transparent, purple crystals of amethyst cover the large plate. The large crystal is 4.0 cm. The crystals really sparkle and are called "cactus quartz" for their form. The terminations are isolated, while the bodies have a prickly, "cactus" look with an overgrowth of smaller crystals. This is the true source for the amethystine quartz crystals (aka "cactus quartz" and "spirit quartz") erroneously marketed as being from the Magaliesberg Range. A lovely example with great color and the iron oxide inclusions are a very nice accent. Complete-all-around and nearly pristine. Ex. Wes Parker Collection.
5.0 x 3.4 x 2.2 cm. Bright green bayldonite richly invests all sides of the massive galena and quartz matrix on this fine specimen from the Brandy Gill Mine at Caldbeck Fells, England. Specimens from this old-time mine are seldom available. Ex. Tony Ellis and Wes Parker Collections.
4.7 x 3.4 x 3.2 cm. An excellent miniature combination specimen from the Yaogangxian Mine of China. Sharp, lustrous, translucent, light chocolate-brown scheelite pseudo-octahedrons to 9 mm are very attractively scattered on a pristine, floater, doubly terminated quartz crystal. Outstanding combination material from this noted locale from the Jaime Bird Collection. Superb white fluorescence on the scheelite.
16.8 x 12.7 x 6.1 cm (largest). A stunning large cabinet pair from a sliced and polished hollow sphere of coral - you can clearly see the pattern on the outside - that has been replaced or filled inside with botryoidal chalcedony. The lustrous botryoids have a gorgeous variety of color. They look like pearls. The hole in one side is really interesting. This is one of those unusual cases where biology meets mineralogy. This specimen is from the Hauck Collection.
5.4 x 4.8 x 4.0 cm. Matrix Herkimer quartz "diamond" specimens are rare because the crystals commonly break off matrix during collecting, as the matrix is commonly very hard. The sculptural matrix on this fine specimen features sharp, glassy, cut gem-like quartz crystals - two aesthetically set on the top and one "diamond" attractively set on either side of the matrix. The large crystal on top is 2.3 x 2.2 cm. This is a rare, visually impressive, complete-all-around, matrix Herkimer diamond specimen from a much less well-known New York locale - Fonda in Montgomery County. Ex. Bob Sullivan Collection.
19.9 x 16.4 x 6.8 cm. Morion quartz is a very dark brown to black opaque variety of quartz. Morion is the German, Danish, Spanish and Polish synonym for smoky quartz when it is totally dark and solidly smoky inside. This a fine large cabinet cluster. The glassy, highly lustrous, translucent crystals, to 8.0 cm, are di-pyramidal with no prism faces and are called morion quartz by some people and beta quartz by others on the market. This is old material from a few famous finds in Brazil. These are high temperature quartz crystals, technically quartz ps. after beta quartz (see MINDAT for a further explanation under "Quartz-beta" at http://www.mindat.org/min-7395.html). The fine, large, complete-all-around specimen is very nearly pristine and certainly exceptional in preservation. It is older material from the Richard Hauck Quartz Collection; and hails from an uncommon Brazilian locality - the Recruta Farm, Vitoria da Conquista, Bahia.
20.8 x 18.7 x 15.4 cm. Ajoite is a very rare copper-containing silicate. Pretty, powder-blue ajoite includes many of the quartz crystals on this striking, very sculptural large cabinet specimen that is studded with porcupine-like quartz needles. This fine piece is from a recent, sudden find from the Messina Mine of South Africa after many years of drought, source of the very best ajoite-included quartz crystals.
6.2 x 5.8 x 5.5 cm. Morganite from the Mesa Grande District of California, which includes the famous Himalaya Mine, is rarely available. A 2.5 cm rosette of lustrous, gemmy to translucent, pastel-pink, compound morganite crystals is very aesthetically set front and center in a fine cluster of intergrown, euhedral, translucent smoky quartz crystals. This excellent, older piece has an excellent provenance, having been in the collection of prominent California collector and dealer Thomas W. Warner. Warner, born in 1915, was a very active collector and dealer from the 1930s until his death in 1955. He is said to have assembled the finest California pegmatite collection of the time. The label for this specimen is featured in Thomas Warner's Mineralogical Record Biographical Archive.
13.3 x 6.4 x 5.6 cm. A stunning, very rare, multiple crystal, cabinet specimen of unique and unusual quartz from a one-time, 2005 find in Madagascar. Specimens are very hard to get today. Purple fluorite octahedrons to 5 mm are richly and attractively included in large, dramatic, intergrown, lightly frosted, transparent quartz crystals on a matrix of smaller quartz crystals. The beautiful, sharply terminated spires are complete-all-around. One of the best pieces from this very small find.
