On the basis of the type, the global garnet market is segmented into almandine, andradite, grossular
, pyrope, spessartine, and uvarovite.
The main mineral compositions of the tailings are quartz, grossular
, lead bismuth vanadium oxide, graphite, and so on.
They are consistent with those reported for pyralspite garnets by Stockton and Manson (1985), and the RI values of all three samples fall within the ranges expected for both pyrope-almandine (rhodolite) and pyrope-spessartine, with or without some grossular
Almandine, spessartine, grossular
, uvarovite, andradite and pyrope are six minerals which are regarded as belonging to the garnet family.
The sets of minerals of this skarn include quartz, calcite, grossular
, augite, and gypsum.
As an East Coast native I was drawn to the case which contained a 5-cm golden beryl (heliodor) from the extinct Slocum Quarry, East Hampton, Middlesex County, Connecticut: a 4 X 8-cm transparent green and pink elbaite from Newry, Maine; and a 4-cm grossular
on diopside with grossular
crystals to 1.2 cm sitting atop an opaque diopside crystal from Eden Mills, Vermont (this grossular
specimen has been photographed many times and is probably the best small specimen ever found at the quarry).
But there are localities famous for mineral growth right here in Canada, one of them being the Jeffrey Mine in Quebec's Shipton Township, famous for prehnite and the beautiful grossular
crystal, a variety of garnet.
Demantoid garnet is a rare and beautiful bright grass green sub-variety of andradite garnet.Tsavolite, is a bright green variety of grossular
garnet, its colour being induced by the presence of chromium.
Diamondiferous zones are characterised by dynamic and thermal metamorphism and the presence of grossular
garnets, glaucophane and other minerals of high-pressure zones.
The best grossular
garnets from the Jeffrey mine, Asbestos, Quebec.
