Q-605  Chalcedony ps. after Anhydrite  SOLD
This specimen is sold but we have others like it in stock.

Agua Fria River, New River Station Area, Yavapai County, AZ

2.1 x .6 x .3 cm

An example of peach-colored Chalcedony replacing an Anhydrite crystal. These Chalcedony pseudomorphs after Anhydrite were collected over a period of 10 years by my friend Al Rose. This material has the distinction of being mentioned not once but twice in The Mineralogical Record's what's new in minerals. Not many of these were found and are much sought after by collectors of Arizona minerals as well as by pseudomorph collectors.

Q-600  Quartz with Chlorite inclusions  SOLD

Shingle Springs, Shingle Springs Mining District, West Belt, El Dorado County, CA

9.2 x 3.1 x 2.2 cm

A large & very clear Quartz crystal that has been included by multi-colored Chlorite giving the specimen a camouflage-like pattern. The front prism face on this specimen has been polished to emphasize the garden-like inclusions of Chlorite. Minor chip on the termination does not detract from the beauty of this specimen. A great Quartz specimen from a locality from which it is not easy to find superb-quality specimens on the market & is comparable to the best from Brazil.

C-331  Sapphire (double terminated)  SOLD

Ratnapura, Ratnapura District, Sabaragamuwa Province, Sri Lanka

1.7 x 1.6 x 1.5 cm

A double-terminated, cornflower-blue Sapphire crystal with yellow terminations. This bi-colored crystal is partially translucent part gemmy and features stepped crystal faces and a lenticular hitchhiker crystal protruding from one side. Unlike like most crystals from the Sri Lankan gem gravels, it is not rounded on its edges. Sri Lankan Sapphires set the standard for form and quality of the species. This crystal has a much better form than is apparent in the photos which had to taken a little over-lit due to the difficulty of trying to capture the two colors of this specimen.

Eonyang, South Gyeongsang Province, South Korea

6.8 x 4.2 x 3.9 cm

This specimen consists of a group of interpenetrating Amethyst scepter crystals with smoky-colored stems.

The crystals of this specimen have an eye-pleasing form. The specimen is complete all around with just a minor imperfection on the termination. Amethyst scepters from this location are hard to obtain and are considered to be classics. This location is now defunct as the property has been converted to an amusement park.

Q-608  Scepter Amethyst  SOLD
Ex Russ Rizzo Collection

Eonyang, South Gyeongsang Province, South Korea

8.4 x 7.4 x 5.1 cm

A large group of Quartz scepters from South Korea. This specimen consists of five translucent smoky-hued crystals with very clear & glassy Amethyst terminations. This specimen also features many smaller smoky crystals around its base. The upper two photographs were taken with a small amount of backlighting to better emphasize the clarity of the Amethyst overgrowths. The termination on one of the lesser crystals shows signs of shattering and being re-healed but is not noticeable as this minor imperfection is on the inside area of the specimen. The largest crystal shows signs of dissolution which is visible as a channel running down one portion of the termination. Groups of scepters from this location were never abundant and always hard to come by. Eonyang was quite famous in the past but never was a prolific producer of specimens, even at its best times. This location is now defunct as the property has been converted to an amusement park.

2.2 x 1.6 x 1.1 cm

This thumbnail-sized Anorthite specimen is from a classic Japanese locality, Miyake Island. The crystal is a floater of off-white color and is coated with a micro-thin film of dark hued glassy lava. Miyake Island is a small island with an active volcano and is famous as the classic locality for Anorthite crystals which were thrown out loose by the July 1874 eruption. Some crystals from this occurrence display metallic schiller caused by discontinuous included films of native Copper and/or copper-zinc alloys.

AD-124  Quartz geode with Calcite  SOLD

Las Choyas, Municipio Aldama, Chihuahua, Mexico

9.5 x 8.5 x 3.5 cm

This geode is a really good example of what the tuffaceous ash flow at Las Choyas had to offer in its heyday. The vug of this specimen is lined completely with sparkling crystals of Quartz upon which glassy, coffee-colored crystals of Calcite have formed. The days when you could get a geode of good quality from Las Choyas at any rock shop are long gone. This specimen came from my personal stash of Las Choyas geodes that were purchased from the Law family at the San Diego County Fair during the 1980's through 1990's.

9.8 x 7 x 6.6 cm

A plate of sceptered Smoky Quartz crystals. Some of the smaller crystal show hints of purple.

G-169  Grossular & Diopside  SOLD

Belvidere Mountain Quarries, Lowell & Eden, Orleans & Lamoille County, VT

1.5 x .8 x .7 cm

A group of lustrous Garnet dodecahedrons on a translucent crystal of Diopside. Garnets from what most people refer to as Eden Mills are some of the most recognizable Garnet specimens from the United States. The proper name for the locality is the Belvidere Mountain Quarries, which lies on both sides of the Orleans & Lamoille County line in Vermont. The color of these Grossular Garnets are captivating, and they are, as is the case with this specimen, often found with beautifully contrasting green Diopside.
