Dioptase with Kinoite and Apophyllite, Christmas Mine, Banner Mining District, Gila County, Arizona

Описание: Dioptase with Kinoite and Apophyllite, Christmas Mine, Banner Mining District, Gila County, Arizona
Specimens exhibiting the distinctive dioptase from the renowned Christmas Mine are highly sought after, with the dioptase-kinoite association from this locality being even more desirable. According to Arkenstone, dioptase from this mine is among the most recognizable specimens globally. The accompanying kinoite, a rare hydrous copper calcium silicate, is known to occur exclusively in the United States and two other countries, as stated by Mindat.
This TN showcases emerald-green dioptase in needle-like stellate sprays and bowties, alongside bright blue Kinoite crystals that sparkle like tiny gemstones. The kinoite occurs both as free-standing crystals (which is unusual), and as inclusions within glassy, water-clear apophyllite* crystals. The extinct mine is one of Arizona's most esteemed mineral localities and a classic U.S.A. site.
Dimensions: 30 x 20 x 20 mm. Ref: MF-13-93.
For those with an interest in mineralogy, the apophyllite at the Christmas Mine is reported to be Hydroxyapophyllite-(K).
