CHRYSOCOLLA SPECIMEN 2
A vibrantly coloured Chrysocolla Specimen 2. This mineral is great quality, featuring a very beautiful shade of aqua blue. Showing classic botryoidal forms with some overgrowth, the main video shows amazing detail. This is a super specimen which will add a splash of colour to your collection. Chrysocolla has a pretty unique colour to the mineral world, the only similar hue being the best quality Turquoise. As with many blue and green rocks, this is an ore of copper. A little Shattuckite is also visible on the matrix.
11.5cm x 9.7cm x 3.5cm, 335g.
Hydrated Copper Cyclosilicate
Cu2-xAlx(H2-xSi2O5)(OH)4 · nH2O.
The name was first used in 315 B.C. by Theophrastus. The name comes from the Greek chrysos, meaning “gold,” and kolla, meaning “glue,” in allusion to the name of the material used to solder gold. André-Jean-François-Marie Brochant de Villiers revived the name in 1808. Chrysocolla forms in the oxidation zones of copper rich ore bodies.
An attractive blue-green that provides a unique colour to the mineral world. Chrysocolla is perhaps more appropriately a mineraloid than a true mineral. Most of the time it is amorphous meaning that it does not have a coherent crystalline structure. At higher temperatures it does demonstrate a distorted crystal composed of Si4 O10 sheets. Chrysocolla forms in the oxidation zones of copper rich ore bodies.
Pure Chrysocolla is soft and fragile and therefore not appropriate for use in jewelry. Chrysocolla is often agatised in chalcedony quartz. It is the quartz that provides the stone with its polish and durability. Druzy Chrysocolla is agatized with a crust of sparkling quartz crystals. A skilled craftsman can produce a lovely and valuable piece of jewellery from swirls of Chrysocolla and sparkles of druzy quartz. Chrysocolla can have a turquoise color and be used as a fraudulent substitute for the more precious stone.
