9.5 x 7.6 x 5.3 cm. This is a superb morganite specimen. The crystal is 5 cm across and glassy, with a unique scalloped surface termination I have only rarely seen on beryls, and on none other from San Diego County that I can recall. Note that this is from the Stewart Mine and not from the more well known White Queen. The piece was probably found prior to 1960. The specimen was illustrated with his beryls on page 137 of the Barlow Collection book (1998). Barlow sold the collection in 1998 and this piece disappeared into the private collection of Lawrence Conklin.
5.2 x 4.9 x 3.8 cm. An aesthetic and superb combination specimen from Shengus, Pakistan of a gorgeous, 3.0 cm, doubly terminated, gem, light blue aquamarine crystal attached to the side of lustrous, jackstraw, dark green tourmalines and accented with a well-placed quartz crystal and albite crystals.
6.8 x 5.0 x 4.2 cm. Lustrous, glassy rose quartz crystals aesthetically fill a vug in contrasting white albite and quartz on this fine specimen from a recent small find at Berilo Branco, Brazil. Berilo Branco produced the world famous "Van Allen Belt" rose quartz crystal specimen in the Smithsonian.
2.4 x 1.4 x 1.4 cm. This fine Colorado amazonite thumbnail is from Richard Kosnar’s personal collection, from his own claim in Park County. The color and form are the superb, the crystal is complete all the way around, and the albite gives it just the right accent.
4.0 x 3.5 x 3.2 cm. Very unusual and showy aquamarine crystals clustered in an aesthetic arrangement with snow-white albite crystals from Ping Wu, China. The gemmy and very glassy, very light blue aquamarine crystals to 2.0 cm, are elongated. Most Ping Wu aquamarines are flattened, tabular. The two large aquamarines have unique, for Ping Wu, terminations, being hoppered and lightly frosted.
4 x 2.4 x 2.2 cm. A fine miniature tourmaline specimen from the Pederneira, with a pure gem, 2-cm “pencil” crystal shooting out from a cluster of smaller crystals – all terminated. The only small matrix contact is underneath. Pretty association of bladed white cleavelandite and lavender lepidolite.
7.8 x 5.1 x 3.9 cm, 6.4 x 5.4 x 4.2 cm. Two specimens of rare "rose" muscovite from a recent find in a pegmatite mine in Taos County, New Mexico. Muscovite is familiar in various hues beyond the usual silver: particularly green, yellow, lavender, and even a reddish orange (Canada). But this is truly a rare color for the mineral - and, it is from a U.S. locality. Self collected by friends of ours in Dallas.
16.9 x 14.0 x 6.8 cm. An incredibly large and rich specimen of translucent, lavender lepidolite, from Peech. This large, heavy specimen is solid lepidolite, and on top, it has formed wonderful crystallized "flowers" with a thin "snowfall" of albite. Lying across the lepidolite is a gemmy, three-centimeter, terminated crystal of tourmaline.
10.8 x 9.8 x 8.8 cm. Here is a very large, transparent crystal of aquamarine, of hexagonal tabular form, from Brazil. This impressive 5-cm crystal is gorgeously set amongst thick books of shimmering, very large sheety crystals of muscovite. Milky cleavelandite adds a final pretty accent.
7.8 x 5.9 x 5.9 cm. It is not unusual to see spessartines on quartz or albite from Shengus, but it is unusual to see them on such a large, sharp and well-formed single crystal of albite. The spessartines, a deep wine-red color, measure to around 0.9 cm (though most are smaller). These are attractively isolated on the stark white albite. On the other side of the albite crystal are two tabular quartz crystals (there are some conventional prismatic crystals on the "underside" as well, demonstrating that this crystal was loose in the pocket, becoming a "floater" and allowing crystals to form on all sides).
9.8 x 7.2 x 5.4 cm. A piece of massive, gemmy feldspar with a pleasing bluish color to it, famously used for carving in old times. It is more historic, than mineralogically interesting, as a sample from North Carolina. Ex. Academy of Natural Sciences Philadelphia Collection.
A VERY RARE morganite from this small mine better known for aquamarines and the occasional tourmaline! The crystal measures 5 cm across and has a very pleasing pink color to it. However, on closer inspection this specimen shows both blue and pink zoning, and the effect is more pronounced in person where you can clearly see blue when looking down the c-axis. This is exactly similar to the famous piece of same provenance known as "The Pala Princess" which has been pictured in Sinkankas' books and noted as a very unique specimen. It has excellent lustre and is mostly translucent, if not transparent per se. For the mine, this is exceptional. It was collected by mine owner Roland Reed in 1982. 9.4 x 5 x 4.2 cm
A really attractive large specimen featuring a classic Little 3 assemblage in decorative arrangement...the smoky in the middle is pristine save for one small contacted face (not damage), and is nicely accented by stark white albite and dozens of glittering little orange spessartines perched on every other species present (quartz, albite, muscovite blades) and even included within the smoky! 12.3 x 7.5 x 7.4 cm
7.5 x 4.5 x 2.9 cm. An uncommon and fine combination specimen from the Shigar Valley, Pakistan. This fine piece has 3 gem species on the crudely terminated albite "bar": a super-gem, water-clear, 4.8 cm aquamarine crystal; a 1.7 cm, nicely terminated, gem, colorless topaz crystal; and both are nicely accented by a 1.2 cm, lustrous dark green elbaite crystal. There are even scattered tiny quartz crystals on the albite.
An unusual specimen that is, surprisingly, a specimen-worthy CLEAVELANDITE on its own merits....whereas the species is usually relegated to host rock or accent mineral and seldom the dominant feature of a nice piece. These lustrous, beige crystals form a wreath over the top of a thin albite crystal. Acquired from the collection of Tim Sherburn, who got it from Louis Spaulding Jr. (current owner of the mine made famous by his father) in 1993. 6 x 3 x 2.4 cm
