Vesuvianite, also known as idocrase, is a green, brown, yellow, or blue silicate mineral. Vesuvianite occurs as tetragonal crystals in skarn deposits and limestones that have been subjected to contact metamorphism. [3] It was first discovered within included blocks or adjacent to lavas on Mount Vesuvius, hence its name. Attractive-looking ...
Manganvesuvianite is a rare mineral with formula Ca 19 Mn 3+ (Al,Mn 3+,Fe 3+) 10 (Mg,Mn 2+) 2 (Si 2 O 7) 4 (SiO 4) 10 O(OH) 9. The mineral is red to nearly black in color. Discovered in South Africa and described in 2002, it was so named for the prevalence of manganese in its composition and its relation to vesuvianite.
Cyprine is a copper-rich member of the vesuvianite group [3] with the formula Ca 19 Cu 2+ (Al 10 Mg 2)Si 18 O 68 (OH) 10. A similar name is given to a Cu-bearing variety but not Cu-dominant member within the group. Cyprine (sensu stricto) was discovered in the Wessels mine in the vicinity of Hotazel, Kalahari Manganese Field, South Africa. [2]

Grossular is found in contact metamorphosed limestones with vesuvianite, diopside, wollastonite and wernerite. A highly sought after variety of gem garnet is the fine green Grossular garnet from Kenya and Tanzania called tsavorite. This garnet was discovered in the 1960s in the Tsavo area of Kenya, from which the gem takes its name.
Rodingite from Maryland. Rodingite is a metasomatic rock composed of grossular-andradite garnet, calcic pyroxene, vesuvianite, epidote and scapolite. [1] Rodingites are common where mafic rocks are in proximity to serpentinized ultramafic rocks.
