18.2 x 13.8 x 10.5 cm. This is about as red as Quartz can get. Obviously the crystals are coated with about as much Hematite (or some other kind of iron oxide) as I have seen from any locality, but the effect is dazzling. The Orange River area in South Africa is well known for these specimens, along with a few others like green Fluorite, and I never grow weary of them. I honestly have never seen Quartz crystals with such impactful brick red color as this. I am told that this specimen was actually collected about 10 years ago by a farmer who had no idea what he found. The piece is in amazingly good shape for the size, and many of the crystals are pristine.
4.2 x 3.2 x 3.2 cm. A CLASSIC, OLD-TIME and showy specimen of lustrous, emerald-green torbernite crystals to 7 mm nicely placed on vuggy quartz matrix from Gunnislake, Cornwall circa late 1800s. The nearby quartz points add character to this fine, old-timer.
12.6 x 12.5 x 3.3 cm. A very large, very fine and dramatic example of the rare Japan-Law twinning of quartz, from the Ed David Collection. This flat, tabular twin is unusually transparent. It is complete all around, with the only contact being the usual bit on the bottom where it was removed from the matrix.
12.9 x 10.9 x 6.4 cm. A large, excellent plate of amazonite and smoky quartz, which passed through both the Clarence Coil collection (1968) and later the McKee collection (#TM-778). Coil was a noted field collector from Colorado who was particularly well known for his amazing amazonite finds in the 60s and 70s. Tom McKee was a major Arizona collector known for the quality of his pieces. The color isn’t intense here, but the geometry is superb. What is most remarkable about this specimen is that is has NO REPAIRS, which is rare for these large combo plates, as they are so often broken apart in the pocket and have to be carefully reassembled. Except for a couple of little dings on smokies and one rear cleave on a smoky tip it is free of damage, as well. The largest amazonite is 4 cm in height and 3 cm across the termination. The smokies measure to 4 cm as well. There is a really pretty balance here of amazonite and smoky crystals.
15.6 x 5.6 x 3.6 cm. This is a very large, very interesting quartz crystal from Pakistan, in that it is weirdly etched all over - with some faces having what look like divots in them, others a jagged surface, and still others a tiered appearance. The crystal is complete and doubly-terminated. It is VERY gemmy through the interior. Small find of last year and large ones are hard to come by. I cannot say I love them for the form, but they make remarkable specimens nonetheless for the beauty of the complex surface, and the reflections thrown off. They LOOK almost lab grown.
6.8 x 1.8 x 1.8 cm. A superb doubly-terminated, complete and undamaged floater of Brandberg amethyst, with what appears to be an internal SCEPTERED phantom! It has a gorgeous "blush" of purple inside, which makes these crystals so unique. This is not only a very fine Brandberg amethyst, but a very distinctive and unusual one as well! Among the better doubly-terminated floaters I have had. Ex. Charlie Key Collection.
9.1 x 4.8 x 4.2 cm. Incredibly sparkly quartz specimen, complete all around. This is the most intense citrine color and sparkle I have seen on one of these, which came out in quantity maybe 4-5 years back now. Just gorgeous! Ex. Charlie Key Collection.
2.6 x 1.9 x 1.5 cm. Three beautiful amethyst scepters here, all an inch or a bit more tall. All beautiful and distinct. Ex. Charlie Key Collection.
17.8 x 10.6 x 4.9 cm. Large plate of gorgeous gemmy orange spessartine garnets on smoky quartz, with no damage except to the bottom periphery and one spot on the right most edge. For the size, the quality of the garnets is unusually good and the quality overall unusually high. Ex. Charlie Key Collection.
2.7 x 2.3 x 1.3 cm. Weird specimen from a small find I had never seen before…translucent GREEN botryoidal fluorite balls to 5mm on little quartz crystals. What an adorable thumbnail, and unusual in my experience. Ex. Charlie Key Collection.
3.6 x 3.6 x 3.3 cm. An unusual specimen from South Africa featuring a few bizarre elongated fluorite shards stretching out from the quartz cluster…just how this formed, I cannot say. Ex. Charlie Key Collection.
5.4 x 4.1 x 2.3 cm. An oddball, never seen the like. This seems to be a hollow cast of chalcedony after stacked hexagonal calcite plates. Charlie was not sure where it came from, except he bought it in Erongo so presumed it was from nearby. Ex. Charlie Key Collection.

5.1 x 3.8 x 2.2 cm. Gorgeous, sparkling quartz crystals included a bright blue by minute inclusions of the rare copper species shattuckite. New finds the last few years. Ex. Charlie Key Collection.
14.6 x 12.2 x 7.3 cm. China has provided us with a plethora of Calcite specimens of all habits, colors and sizes. This specimen is a new piece from Chenzhou featuring pseudo-pyritohedral, very light straw colored crystal on Quartz matrix.
10.4 x 4.1 x 3.4 cm. This would be a fine specimen of Arkansas quartz even without the RARE (for these) internal phantoms. It has an unusual lovely silky surface luster with striations. Phantoms probably exist in these more often than is known, but the clarity of the crystals prevents them from being seen. In this case, the internal crystals were coated with a whitish mineral before being engulfed by later growth. This is actually TWO phantoms that have grown against one another inside of TWO outer crystals! The crystals are damage-free and just gorgeous.
