She chooses the blues of lapis lazuli and azurite from Chile; the greens of malachite and earth from Verona, Italy; the yellow ochres from France; the red siennas from Italy and cinnabars from China; the browns of raw umbers from Cyprus; the purple of vesuvianite from South Africa; and the luminous whites of oyster shells from Japan.
The veins are surrounded by a 5- to 10-cm-wide alteration zone that consists of calcite, dolomite, diopside, hedenbergite, vesuvianite, and base-metal sulfides.
Also aluminium hydroxide Al[(OH).sub.3] as nordstrandite or vesuvianite ferrian [Ca.sub.19][(Al,Mg,Fe).sub.11] [(Si,Al).sub.18][O.sub.69][(OH).sub.2] are found.
For instance, trace amounts of limonite impart a yellowish brown color; serpentine, hornblende, and diopside produce varying tones of green; minute quantities of hematite, vesuvianite, and garnet introduce a reddish brown hue; sphene, epidote, and chondrodite give a yellow tinge; and plant and animal remains produce shades of dark gray to almost black.
In his InnSuites room Dennis had about 20 flats of loose grossular crystals of thumbnail dimensions, plus a few big hunks of white calcite with red grossular crystals (and a few brown vesuvianite crystals) investing them.
On the north-facing slope of the ridge that separates the large drive-in tunnel and the main upper portal of the Brown Monster mine, a skarn containing large (1-3 cm) green diopside crystals and brown vesuvianite crystals in blue calcite was observed.
In the show's "Alpine Strahler" domain (again), Chianale Franco (Via Osasco 71, 10141 Torino, Italy) put out some flats of fine epidote specimens from Val di Viu (northwest of Torino) and of vesuvianite from Bellecombe, Aosta.
The Montreal-Coleraine mine, also known as the Montreal chrome pit, was the source of an emerald-green, chromium-bearing variety of vesuvianite named "chrome-idocrase" in 1913 (Horvath, 2003).
The mine at Asbestos produced wonderful specimens of orange grossular ("hessonite") garnets and some of the best prehnite, pectolite and vesuvianite specimens in the world.
