Buy natural vesuvianite in our shop

Vesuvianite, also known as idocrase or californite, is a fascinating and multi-colored silicate mineral that ranges from green, brown, yellow, to blue. This gemstone forms primarily as tetragonal crystals in skarn deposits and limestones that have undergone contact metamorphism, resulting in its diverse and vibrant colors.

The stone was first discovered in blocks of rock or areas adjacent to lava flows on Mount Vesuvius, which is how it got its name. Since its discovery, vesuvianite has been found in various locations worldwide, with some of the most attractive crystals being used as gemstones. Prominent locations where fine crystallized vesuvianite has been discovered include Mount Vesuvius in Italy and the Ala Valley near Turin, Piedmont.

Properties and Identification

Vesuvianite has a specific gravity of 3.4 and a hardness of 6.5 on the Mohs scale, making it quite suitable for jewelry. The mineral was named “vesuvianite” by A. G. Werner in 1795 because of the fine crystals found at Mount Vesuvius, which were typically brown in color and found within the ejected limestone blocks of Monte Somma. Another name for vesuvianite, “idocrase,” was coined by R. J. Haiiy in 1796 and is also widely recognized today.

Vesuvianite Varieties and Sources

Vesuvianite occurs in several interesting varieties. One of these varieties is the sky bluish vesuvianite known as cyprine, found in places such as Franklin, New Jersey, USA. The unique blue coloration of cyprine is attributed to the presence of copper impurities within its structure. Another notable variety is californite, which resembles jade and is sometimes called “California jade,” “American jade,” or “Vesuvianite jade.” This jade-like vesuvianite is a popular choice for carving and ornamental use.

Xanthite is a manganese-rich form of vesuvianite, while wiluite is an optically positive variant found in Wilui, Siberia. These varieties add to the mineral’s diverse characteristics, making vesuvianite a fascinating subject for both mineralogists and collectors.

Cyprine Characteristics

The fibrous, copper-bearing variety of vesuvianite known as cyprine was first identified in 1905 in a small dump of unknown origin at the mouth of the Parker shaft. The mineral appeared as bundles of slightly radiate needles scattered through a coarse-grained feldspathic pegmatite. Cyprine is abundant in these specimens, with a characteristic blue to blue-green color. It is often found alongside minerals such as manganophyllite, yellowish garnet, and native copper, which occur as threads and irregular fragments.

Initially, cyprine was thought to be a new mineral species, and its identification involved careful analysis to ensure that no associated metallic copper was mistaken for copper combined within the mineral. The analysis revealed similarities to cyprine from Tellemarken, Norway, though some differences in composition were noted.
