This lovely Serandite is a floater crystal, and has an embedded Aegerine in the top that adds contrast to this richly colored mineral. For its size, this piece is top notch. The mines in Mont St. Hilaire are all closed, and sadly pieces such as this one are irreplaceable. It comes in a thumbnail box, with its original hand written label, assembled by famed thumbnail collector Wendy Melanson of Hawthorneden Inc.
This Uvite has a deep green color, and is pleasantly "stacked," vertically. It has a sprinkling of Magnesite and Quartz crystals, making it a desirable specimen from Brumado. This piece originated through Hawthorneden, back when they were readily being found. Since then, the supply of good Uvites has dried up. Pic #3 is the back side of the specimen, also attractive and with a small area missing a crystal (not too eye catching and it's on the back!).
Once regarded as Poldervaartite, this piece was later known to be Olmiite due to a higher concentration of Manganese than originally observed. This piece has all the best attributes from the Olmiite find that was part of the Charlie Key collection (which this came from), from a pocket mined around 2000. It has a rich color, and a bright sparkly luster. The form is good as well as the spherical habit of the mineral is plainly seen, while attached to the matrix. The newer finds, typically have a lighter color.
Once regarded as Poldervaartite, this mineral was later known to be Olmiite due to a higher concentration of Manganese than originally observed. This piece shows unique, bright barrel-like crystals on a matrix covered with druzy calcite. It is mounted on a 1 1/4" acrylic base (not pictured). There is a small ding on the mid right section of the piece, which is easily seen in the pics. Overall, a good sample of this interesting mineral.
Once regarded as Poldervaartite, this mineral was later known to be Olmiite due to a higher concentration of Manganese than originally observed. This was found around 2000 from a substantial pocket, purchased by Charlie Key. This fine example shows crystals of Olmiite with two different colors; one a milky beige, and the other a more transparent salmon color. It's in great condition. It has a glassy, bright surface. It comes mounted on a 1.25 inch/ 3 cm acrylic base.
Two very large Sphalerite crystals are pleasantly perched on a bed of clear Quartz crystals. On top of the Sphalerites are water clear Drusy Quartz crystal clusters. This piece is aesthetic, especially in its contrast. The dark orangey Sphalerites vs. the white/clear quartz. The Sphalerites are relatively rounded, vs. the Quartz pointiness. And finally the tiny, fine druzy clear Quartz contrasts the larger cluster of points. It's in good condition overall. There's a minor blemish on the far right side of the lower Sphalerite crystal. Comes with a 1.25 inch three-prong acrylic stand.
Mexican Opal from Jalisco is prized for its transparency, fire and stability. I acquire this opal directly from the miners, who cut and polish the pieces by hand. The opal forms in a reddish matrix and when extremely good pieces are found, they carve away the matrix, and polish the remaining opal. The net result is a totally unique, highly lustrous free form. It can be set in jewelry or left in its own case to be displayed. This excellent example weighs 10.90 carats.
This Stilbite Specimen was found in the Deccan Plateau, in India. This ancient basalt flow is the greatest producer of Zeolites such as Stilbite. This is a fine example given its aesthetic crystallized 'spray.' The primary crystal is a creamy white color, and it's growing on a base of peach colored Stilbite. It displays easily without a stand, from several directions. For a common mineral, this is a superb example.
Herkimer Diamonds are a special variety of Quartz, found in Herkimer county, New York. The deposit occurs in dolomite (silicified limestone) and is incredibly difficult to break. Fossils are found alongside Herkimers, that further indicates a low temperature crystallization. Miners use heavy sledge hammers and chizels to remove many feet of overburden, to expose the pocket layer. Herkimers were named by General Herkimer in the mid 1800's. This is a very clear, beautiful example of two inter-grown Herkimer Diamonds. It's well over 1 1/2 inches long and is very gemmy and reflective. In the larger of the two crystals, there is a substantial gas bubble trapped inside a fluid cavern that moves about 2 mms, when you angle the crystal down. The two crystals may have been reconstructed, but I see no signs of epoxy under fluorescent light.
