BRILIANT ELECTRIC BLUE acicular crystals of clinoclase, forming rosettes and ballshaped aggregates, on a bit of matrix.This is a beautiful thumbnail with unusually intense color. It was most likely found in the early to mid 1800s when this region was productive of specimens. Formerly in the collection and with label of Willard Perkins, the collector who invented the so-called "Perky Box" for thumbnails.

This old time specimen is probably from the early 1900s, and is from a closed underground copper mine 50 miles north northwest of Lovelock (see MINDAT). This particular specimen is large, gorgeous, and important as a superb US classic and also as an example of the species. The botryoidal balls of clinoclase are to 7mm, and have an intense blue-green color saturation to them. The lustre, though, is the best thing - it is freaky bright and intense also! The piece practically glows from a shelf, even in minimal lighting. It is a historic piece from the collections of Robert Jones and then of Phil Scalisi and James Zigras. For what this is, it is nearly iireplaceable in any collection of important US material
2.8 x 2.4 x 2.0 cm. A SUPERB, AESTHETIC and OLD-TIME Cornwall specimen of a vertical cleft lined with sparkly, midnight-blue microcrystals of clinoclase and bridged by lustrous, forest-green needles of olivenite (a rare combination and habit). This is a beautiful, classic and very desirable combination piece from Cornwall. This piece is easily over 100 years old.
3.4 x 3.0 x 2.0 cm. A superb, CLASSIC and old-time toenail of two, well-placed vugs on gossan matrix richly lined with lustrous, blue-green liroconite blades and sparkly, dark blue clinoclase microcrystals. Liroconite, in combination with clinoclase, are Holy Grail species for Cornwall or English collectors, among the rarest ever found in beautiful crystals, and this is a good one that is a display specimen AS WELL AS a reference piece. Mined in the 1820s-1850s from this type locality.
6.5 x 4.3 x 3.5 cm. A CLASSIC, OLD-TIME and EXCELLENT combination specimen from the famous Wheal Gorland of Cornwall. Lustrous bundles of teal, acicular clinoclase (so intensely colored they were mistaken for connellite by me) compliment and contrast lustrous, green olivenite needles with glassy quartz crystals in a very colorful vug in coarse milky quartz. Specimens of this RARE combination and quality came out in the mid 18th century and are much desired.
5.2 x 4.2 x 2.2 cm. A CLASSIC, OLD-TIME and rich Cornwall specimen of glassy, multi-hued blue clinoclase microcrystals lining numerous vugs in quartz-rich matrix. This excellent piece hails from the Type Locality - Wheal Gorland and was certainly mined in the 1800s. Specimens of this quality are seldom on the market.
5.9 x 4.9 x 2.1 cm. On a weathered limonite matrix are a few drusy clusters of sparkling, deep teal blue clinoclase, to .2 cm across, a copper arsenate. Associated with the clinoclase are tabular, green crystals of chacophyllite, to .4 cm across, a copper aluminum arsenate. From the collection of James E. Moresby White. Ex. Carnegie Museum Collection.
5.3 x 3.5 x 2.9 cm. A CLASSIC, OLD-TIME and showy specimen of lustrous, curved, indigo-blue/turquoise clinoclase plates RICHLY lining both sides of a vug on matrix from the famous Tintic District of Utah. This is a HIGHLY REPRESENTATIVE old-timer of the species and locality, and for its richness quite important despite the slight contacting/bruising. Ex. Don Belsher Collection. The old card says that this piece was obtained in a trade in 1946 (by the previous owner before Belsher)! While not pristine, the piece has a lot of color impact and historical significance.
3.1 x 2.8 x 1.5 cm. An OLD-TIME and showy specimen of mostly botryoidal, blue-gray clinoclase bordered by nicely contrasting malachite from the famous Mammoth Mine, Tintic District, Utah. Clinoclase is a rare copper arsenate and this is highly representative, classic material of the species and famous locality. Comes with old label. Ex. John Ydren Collection.
5.0 x 3.4 x 3.2 cm. A CLASSIC, OLD-TIME and rich Cornwall combination specimen of glassy, multi-hued blue clinoclase microcrystals and green olivenite microcrystals covering two sides of the quartz-rich matrix. This excellent piece hails from the clinoclase Type Locality - Wheal Gorland and was certainly mined in the 1800s.
10.1 x 7.6 x 4.8 cm. A treasure trove of mineral species is nestled in a protected vug, highlighted by a spherical ball of lustrous, blue-green clinoclase: a rare copper asenate/hydroxide. The best upright-standing cluster measures .7 cm across. Spears of splendent purple blue crystals, to .1 cm in length, may be azurite or perhaps even linarite. Tabular, translucent white crystals of baryte, to .7 cm across, are also a part of this pocket. A crust of rich green malachite forms the innermost portion of the vug. Ex. Lawrence Conklin, New York State Museum, and George F. Kunz Collections.
4.0 x 3.3 x 2.8 cm. The Majuba Hill Mine is justly famous for secondary copper minerals like clinoclase, an uncommon copper arsenate. The top of this matrix specimen is covered by a druse of deeply colored, sparkly, blue clinoclase crystals. Ex. Harold Urish Collection.
7.2 x 5.1 x 3.1 cm. A very rich and colorful specimen of microcrystalline clinoclase from an unlikely locality: Missoula County, Montana. Although the crystals are micros, the piece overall is rich and colorful, and obviously a historic rarity for the mining districts of Montana. Ex. Philadelphia Academy of Sciences Collection.
3.6 x 3.1 x 2 cm. Brilliant crystals of lustrous deep blue (with a hint of green) 3-4 mm Clinoclase, typical in color but of a more equant habit than the micro blades normally seen from other locales such as Cornwall. The associated green mineral may be the rare arsenate Parnauite or Cornwallite. Ex. Charlie Key.
6.7 x 5.3 x 2.6 cm. Super lustrous and sparkly, midnight-blue clinoclase crystals richly cover the vuggy gossan matrix on this fine specimen from the Majuba Hill Mine, Nevada. The clinoclase is nicely complimented by light blue-green chrysocolla. Old material from the Dick Jones Collection, collected in the Copper Stope in June, 1978.
