A large and fine old Swiss Orthoclase crystal that is a well formed Manebach twin with fine edge striations. Several older labels included date this back to the 19th century. This Adularia is very large, translucent to transparent and with textbook perfect form. From just the right angle the fine striations make an interesting display of diffraction colors and shows a rich iridescence. Classic and impressive.
Inesite with Quartz, Hubetite etc.
Fengjiashan Mine (Daye Copper Mine), Edong District, Daye County, Huangs
7.2 x 7 x 5.2 CM (cabinet)
A fine Chinese Inesite from the Daye mine (Fenguashian Mine). Great esthetic with a very delicate, perfect standing spray of Inesite on top of a matrix of smaller Inesite, Quartz and Hubeite crystals. Excellent form and color, this has the richest red-orange hue that is most desirable. Not much has been found in recent years and little of that has good form or color. An impressive specimen for the mineral and for the locale.
A bright, striking Dioptase with sizable, perfect emerald green crystals on a etched matrix. From Altyn-Tyube, this is of exceptional quality for that location, and in fact is a choice specimen from anyplace else too. Sharp perfect crystals to 1.3 CM long are clustered in a sizable mass, a few micro tufts of Malachite are also note. Most Altyn-Tyube pieces have much less visual impact.
