6.4 x 5.6 x 4.4 cm. A group of golden, transparent calcite crystals, the largest 2.5 cm, aesthetically clustered on the side of the vug in which they formed. Ex. Feist Collection.
8.8 x 6.4 x 4.9 cm. An aesthetic specimen of Dal’negorsk calcite, where the poker-chip crystals have massed together into a plateau with a wall rising behind it. The crystals have sharp faces, and a gleaming luster.
10.1 x 7.8 x 3.3 cm. A big, rich specimen of pink cobaltoan calcite from Bou Azzer. The crystals here have an unusual peach tone to them. They are in fine condition, with none of the common bruising you see on so many of these.
14.9 x 7.8 x 4.3 cm. This large shard of matrix was loose in the pocket, allowing sparkly calcite crystals as well as a patch of transparent yellow ones to form all over it. But the main thing here is the 2.2-cm, light teal-blue fluorite, with its complex crenellated edges and internal purple phantom. The edges look less white and "crusty" in person - what you are seeing is the blocky edge growth patterns and some tiny calcites that have formed in the recesses. Near the large crystal is a very sharp and pretty little purple phantom.
10.5 x 7.2 x 3.5 cm. A superb cabinet combination specimen from the San Carlos Mine of Chihuahua, Mexico. Lustrous, caramel-colored, hexagonal vanadinite prisms to 1.1 cm are festooned on the 3-dimensional sulfide matrix covered with glassy, colorless, nearly transparent calcite rhombs. The calcite rhombs grew around the vanadinite prisms in many cases.
12.0 x 7.6 x 6.7 cm. Lustrous, thin, tabular, pastel-yellow, wulfenite crystals to 1.7 cm are richly scattered on the 3-dimensional gossan matrix covered with frosted, colorless calcite rhombs on this fine, old-time specimen from the Mina Ojuela of Mexico. Specimens of this size and quality probably came out in the 1960s. Ex. Consie Prince dealer stock.
Mark my words: five years from now, thousands of collectors are going to be KICKING themselves for not buying fine Elmwood specimens when they were still available. This piece was good enough to be in Ed David's collection, probably for its absolutely exceptional association and display qualities. The whopper twin (over 12 cm) stands up at an angle from a bed of barite with gemmy little calcites sprinkled over it. There is a small ding at the upper tip, but take into consideration that almost ALL large calcite twins from the Elmwood have tip dings, and therefore they are generally more accepted than with other specimens. Somewhat better in person... 11.5 x 11 x 9.5 cm
Gemmy-tipped crystals growing out in both directions from a central spine, with accenting galena. 10.5 x 8.5 x 3.4 cm
A beautiful CABINET plate of sharp, lustrous and translucent colorless calcite rhombs to 3.2 x 2.7 cm from a very uncommon, but known Indiana locality. Normal peripheral damage from collecting, but ALL of the central calcite rhombs are pristine! Old material collected in teh 1970s by a Houston collector 13.3 x 7.5 x 5.3 cm
A large and very unusually shaped, lustrous, and translucent CABINET-SIZED calcite crystal from Charcas with a smaller attached crystal. The specimen has a very sharp chisel termination and one side of the large calcite crystal has a stepped growth pattern. This piece is MUCH BETTER in person, as the contrasting gray and colorless tones caused many of the details to wash out. Minor contacting and a few bruises do not diminish this specimen, the likes of which I simply have not seen before from Charcas in this size 17.2 x 5.3 x 4.5 cm
Big, gemmy crystals to nearly 2 cm fill this inner side of the hinge of this shell. Can be displayed either upright or from the side. There is some minor damage to crystals at the base but it gets lost iin the overall context, and its one of the most colorful and lustrous pieces we had obtained when we bought much of the 2003 find. 7 x 5 x 4.5 cm
9.6 x 5.4 x 4.4 cm. A rich covering of spiky calcite scalenohedrons, with a light cream to caramel color, are clustered around a shard of matrix barely visible through the carpet of crystals. Very pretty piece from a Spanish locality better known for its fluorites.
A strange "crystal" composed of two scalenohedral outgrowths from a central (modified) rhombohedral calcite crystal! The first glance shows it to be a single doubly-terminated crystal but in reality it is an in-line cluster of 3 crystals grown together. Very interesting! Complete all around save slight matrix contact on bottom of central xl 4 x 3 x 2 cm
10.2 x 9.8 x 4.3 cm. Here you have a cluster of water-clear crystals of fluorite – the large one measures 2.2 cm along the edge - on a bed of spiky calcites peppered with little iridescent chalcopyrites. Near the fluorites are linear calcite pseudomorphs after an unidentified mineral. Ex. Stoudt Collection.
20.4 x 18.9 x 9.4 cm. From mining in the 1970s or prior, a huge example of Pugh Quarry calcite, out of the George Feist Collection. The central, large, light amber compound crystal measures 13 cm in height by over 9 cm across. It has this complex, multiply-terminated form, with dozens of sub-terminations leading up to the pointy top. Another crystal has grown across the bottom of it at a 45 degree angle. Smaller crystals surround the base of the large one - in fact, they form the matrix, as this piece is all crystal.
