Two parallel terminations of transparent “rock Crystal” quartz emanate from a single base. Even for quartz, crystals of this size and quality are rarely offered for sale. The luster appears to be more muted which gives off a softer glow. There are a few “wilbers” on the terminations, but the sheer size and quality are not to be denied, and it displays easily and well. 22 x 8.4 x 8.3 cm
A layer of rich pink rhodochrosite, in mm size crystals, encrusts a clear quartz druze, which, in turn, is deposited on a sulfide matrix. There is an aesthetic sculptural quality to the specimen. Not significant for either species perhaps, but a darned cute combo! 9.5 x 8 x 4.2 cm
Perched on a matrix of druzy white quartz, are three splendent and super-sharp crystals of pyrite. The crystals, which measure up to 2 cm across, are equant cubo-octahedrons. The top one hangs off and is complete all around! Very aesthetic! 10.2 x 7.1 x 6.3 cm
A doubly terminated, opaque quartz crystal forms the matrix for several unusually large, lustrous and equant, jet-black brookite crystals. The brookite crystals reach 1 cm across which is very large for the locale. They display phenomenally on the contrasting matrix. This is not the norm for Magnet Cove brookite! 7.9 x 2.6 x 2.4 cm
From a well terminated axis, stepped crystal terminations cascade down the specimen in sparkly, purple display atop of a core of smoky quartz (a single crystal underlaying the drapery). This is one of the more interesting amethysts I have seen. Unusual locality, too! 7 x 3.4 x 2.1 cm
This is an interesting combo piece. On a matrix of quartz and albite var. clevelandite is a 3.5 cm tall, doubly terminated, lustrous, pink elbaite with a .3 cm thick rim of green. It sits smack dab in the middle, very nicely balanced on the matrix . The specimen is complete in front, though part of the quartz is broken in back, leaving the tourmaline tip freehanging as shown in the lower-right pic. I should say that it is stabilized (with a bit of glue). The base of the quartz is contacted and since it is flat makes a natural and perfect display base. 7.1 x 7 x 5.3 cm
Jauntily perched on a matrix of druzy white quartz, are doubly terminated barrels of light brown pyromorphite, to 1.5 cm in length. The luster is very good and I particularly like the arrangement of discrete crystals. These are HUGE and very fine for the locality, where smaller crystals predominate. Also, the piece as a whole is in unusually good condition. 9 x 6.3 x 4.2 cm
8.3 x 2.4 x 1.3 cm. Hallelujah Junction is a well-known American locality for quartz sceptres, and this specimen shows why. The sceptre cap is not subtle at all - it is quite dramatic, and to add to the aesthetics, the smoky color is concentrated in the tip rather than all the way down the crystal. The crystal is in fine condition.
Nice because of the slight iron inclusions which give it a bit of color. There is a minor ding or “Wilber” on the top right portion of the specimen, but it is insignificant and the piece is in good condition otherwise . 3.9 x 3 x 1.3 cm
I know its just quartz, but this is an fine example from the Ouachita Mountains of southeast Oklahoma. This is much better than anything I personally have seen collected from this area. The crystals are all transparent with wonderful luster and horizontal growth striations. The largest crystal is right at 5 cm in length. There is an occasional ding on some minor crystal tips, but, I would gladly make room for it given teh quality for the location and the overall showiness of the piece. 8.3 x 5.3 x 4.8 cm
WOW! Rutilated quartzes of such size are VERY rare and a SMOKY one, I have never seen...this piece, despite its size, is in pretty good shape with just minor edge wear in the form of a few dings here and there. It is NOT POLISHED as are so many, particularly larger specimens, of rutilated quartz. That would have been a tragedy! It is, rather, well terminated, nearly transparent, and just filled with brilliant golden rutile needles that exceed 2 inches in length. Again, pieces like this usually enter the market with the terminations machine polished but this one is as it came out of the ground. It is MUCH better in person! 13 x 11.1 x 7.7 cm
Transparent, doubly terminated, quartz crystal (7 cm). Subsidiary, transparent quartz crystals to 1 cm add to the beauty of this specimen. 7 x 2.9 x 2.3 cm
This gorgeous smoky “gwindel” or twisted quartz crystal is totally transparent and has wonderful luster. The contorted twist is easily visible! Smoky gwindels of this deep hue, from Switzerland, set the standard for this material and are highly desirable and hard to find on the market. There are a few frankly trivial minor dings or contatcs that really do not show off so visibly against the black and transparent background, but the price has been lowered accordingly. The "back" side, with the labels, is actually just as preferred a display side as the front! THis one, for the quality, is a downright steal.... 6 x 5.2 x 1.7 cm
With the demise of the Himalaya Mine, quality matrix specimens of US tourmaline are becoming more scarce. This specimen features a 5.5 cm pink tourmaline, which had been partially broken over time by tectonic movement and then continually rehealed in the pocket, resulting in a crysatl with an obvious curvature! This is characteristic of the Himalaya and is quite interesting. It has one repair, at about 1/3 up the crystal. Besides the obvious quartz, there are blades of albite along with a few lepidolite crystals, making this a wonderful pocket combination specimen showing much about the environment these things form under. 12.9 x 9.7 x 7.3 cm
This unusual combination specimen features clusters of 1-cm crystals of white calcite and colorless quartz contrasting with several splendent, black, ilvaite crystals to about 1 inch. All of this sits on a matrix of massive hedenbergite (sawed flat on the bottom to stand). All of the upright, major ilvaite crystals are fully and magnificently terminated, with the only damage confined to the periphery and thus to the less significant sideways-pointing crystals at the base. Ilvaites of this quality came out richly in the late 80s and the 90s but have since completely evaporated from teh market. Now a Russian classic! 6.5 x 4.6 x 2.7 cm
