4.0 x 3.7 x 2.6 cm. This is a fine Mt. Xuebaoding combination miniature. A 1.8 cm, tabular, water-clear aquamarine crystal with facet-like faces is beautifully set upright on highly lustrous, twinned, jet-black cassiterite crystals. Very aesthetically complimenting the aquamarine and cassiterite are four more aquamarine crystals and an interesting cluster of honey-brown muscovite plates.
10.4 x 2.6 x 1.9 cm. A strikingly unusual, doubly terminated, torpedo-shaped, cabinet aquamarine from recent finds in Pakistan. The terminations are highly unusual on this crystal. The primary termination is rounded, frosted, is nearly colorless and is partially notched. The other, pinacoid termination is strangely notched and tapered. The middle portion of the crystal is very gemmy and the blue color saturation is variable throughout the length of the crystal. This is a pristine aquamarine that is very nicely accented by the bit of cradling matrix.
7.5 x 6.0 x 5.1 cm. A 3.8 cm, vivid green, emerald crystal is aesthetically set in quartz-rich matrix on this showy specimen from recent Chinese finds. The sharp, prismatic crystal is lustrous and translucent. Highly representative of the species and locale, despite the broken terminations. Ex. Wesley Stark Collection.
1.2 x 1.1 x 1.0 cm. A very rare, doubly terminated, blue-green aquamarine crystal from one of Colombia’s great emerald mines - the Chivor Mine. One-half of this glassy, textbook, hexagonal crystal is water-clear, while the other half is translucent. This is older material from the Dick Jones Collection. Very nearly pristine. Weighs 12.22 carats or nearly 2.5 grams.
6.1 x 5.8 x 4.4 cm. A very aesthetic cluster of gemmy and lustrous aquamarine crystals beautifully framed by pearlescent, gray-brown muscovite books from recent finds in Pakistan. The crystals have excellent blue color, are gemmier toward the terminations and the long crystal is 4.0 cm.
13.5 x 11.1 x 3.9 cm. Large red beryl plates are somewhat rare, for many reasons (they are often broken up; and they don’t seem to form a lot in the first place). This unusual and showy large specimen has 2 dozen crystals, to 1 cm in size, festooned all about the contrasting rhyolite. The mining of this material is basically at a stop, and it remains a unique locality. They were found, and now the best part of the deposit is inaccessible, so specimens are drying up rapidly on the market. Weighs 500 grams.
4.8 x 1.2 x 1.0 cm. A beautiful, gemmy and lustrous, doubly terminated, yellow-green heliodor beryl crystal from a new find in Vietnam. This crystal is from the much less well-known Bin Thuan Province. This is a totally gem crystal, with virtually no internal crazing. The well-striated faces account for the appearance. Weighs 10 grams.
11.3 x 7.0 x 5.6 cm. A surprising, very rare specimen featuring a very sharp, fine, 2-cm tantalite crystal in matrix with associated lepidolite and morganite. Tantalite crystals are rare, and of this quality extremely rare, from the County. The morganite is a bonus at the other end of the specimen. Ex. William Larson Collection.
4.8 x 4.7 x 4.0 cm. A thick, robust aquamarine crystal with excellent pastel blue color and very good lustre. Large, sharp aquamarines are not that common in the county. For whatever reason, we get tourmalines beryls when they come tend to be morganite. True aquamarines, of any quality, are exceedingly rare in San Diego. This mine is known for quartz more than for beryl, as well. Ex. William Larson Collection.
5.0 x 2.3 x 1.8 cm. A rare old-time specimen, this probably dates to the early 1900s and the era when gem miners prospected all over the mountains of San Diego and Riverside for tourmaline and beryl. Bill Larson repatriated it from a European collection where it had been all that time, and it is from a locality in what is today a very developed suburb. The crystal is a little rough on the edges due to solution effects in situ and not to damage from mechanical wear, but it is complete and terminated. Ex. William Larson and Dr. F. Krantz Collections.
7.4 x 6.6 x 4.5 cm. A strange, etched, organic-looking morganite crystal with a hexagonal termination remaining atop the elongated, etched body. It has a pale pink color, and is very attractive, if unusual, in person. It shows crystal form, still, though is overall stretched and strange in appearance. Accents of muscovite are scattered over it. It is a floater. Ex. William Larson Collection.
3.7 x 2.7 x 1.6 cm. A very old, very sharp morganite crystal that makes for a fine small miniature. It is unusually gemmy and well-formed, for this locality, complete save s bit of damage at the top-right-rear of the termination. A small hint of purple lepidolite included in the base narrows the mine origin to the Pala region, corresponding with the old labels stating "Pala" as locality. Bill then narrowed it down to King Mine. This was in the Scott Williams collection by 1958. Weighs 26 grams. Ex. William Larson Collection.
5.2 x 4.5 x 4.2 cm. A very rare specimen, consisting of a matrix aquamarine from this small pegmatite. The crystal is highly lustrous and has beautiful surface ripplings on the termination. It is 2.7 x 2.5 x 2.5 cm in size. Ex. William Larson Collection.
4.0 x 3.1 x 2.3 cm. A rare and small locality, this place produced only a few pockets of good material so far, and this beryl comes from one of them. At 50 grams, and fine blue color, it is a respectable county aquamarine from a locality most people will never hear of. Ex. William Larson Collection.
9.7 x 8.7 x 8.5 cm. Morganite from this mine is, typically, admixed with aquamarine and of pale color. This is an unusual specimen with barrel-shaped hexagonal crystals, extremely gemmy and clean inside, to 3.5 cm. The horizontal crystal, 3.5-cm across, is complete and doubly-terminated. The slightly fatter crystal, approximately 3 x 3 x 3 cm in size, has a shallow, conchoidal, curving break on its upper edge of the termination. Ex. William Larson Collection.
