Cavansite blueberry Mineral Specimen, this piece is remarkably perfect.This piece comes on an acrylic display pedestal and it is attached to that using mineral tack. (weight is including that display piece). Origin: India Size: 11 mm x 12 mm x 11 mm weight: 5.5 grams Cavansite is a beautiful and rare mineral, which explains its recent popularity. It was only discovered in the last 30 years and is found in only a few localities. It's Color is greenish blue to deep ocean blue. We have also heard the term electric blue used to describe Cavansite. Cavansites' Crystal Habits are mainly crystal aggregates that consist of tufts or spherical rosettes with pointed crystals. These beautiful blue Cavansite rosettes, mixed among snowey zeolites, make spectacular crystal specimens. Also some larger crystals show an unusual internal reflection. Cavansite was first described as a blue associate of zeolites in 1968 by L.W. Staples. The locality was a road cut near Owyhee Dam, Malheur County, Oregon. The best known crystallized Cavansite. Comes from the famous zeolite quarries of Wagholi, Poona district, Maharashtra, India. The Wagholi Quarry is a huge basalt quarry. It was primarily worked for construction materials. But many wonderful zeolite specimens have made their way out. In recent years, reports tell of three other quarries in this region which contain Cavansite. The original Cavansite from Owyhee Dam, Oregon was a rather insignificant mineral discovery. It had interesting crystallography and chemistry, but it was just low-grade Heulandite with pale greenish inclusions. An unusual blue mineral, later also identified as Cavansite, began showing up among zeolites from 'Poona' in late 1973. It caused quite a stir, as the specimens were actually attractive. The material first came to the Tucson Show in early 1989. It was an immediate hit with it's vibrant blue color. The Indian specimens had needle crystals up to 10 mm long, forming sps and tufts on white Stilbite. New finds have repeatedly earned rave reviews. This area is called the Deccan Traps. It is a famous source of zeolite specimens, currently the area covers approximately 470,000 square kilometer in western India, but probably used to cover at least 1.2 million square kilometers. Most of the Deccan Traps are composed of an Augite basalt that is chemically and mineralogically extremely uniform. The basalt in this area is generally contains few vesicles. The only reasons for the abundance of zeolites and other minerals from the Deccan Traps are its immense area and extensive use of basalt for road material. Unfortunately if t ever was a quarry with abundant vesicles, it would probably never be worked. Payment Options I accept payment via credit/debit card (PayPal).
