Tremolite Spheres, Etc.
Tremolite is a member of the amphibole group of silicate minerals with composition: Ca2Mg5Si8O22H2. Tremolite
forms by metamorphism of sediments rich in dolomite and quartz. Tremolite forms a series with actinolite and ferro-actinolite.
Pure magnesium tremolite is creamy white, but the color grades to dark green with increasing iron content. It has a hardness
on Mohs' scale of 5 to 6. Nephrite, one of the two minerals of the gemstone jade, is a green variety of tremolite. There's
a tremolite location near my home in the town of Felch, Mi. The tremolite here ranges through white, light pink and different
shades of green.

reminds me of nephrite jade, although it's considerably softer. Approx size: 49x38x20 Weight: 36 grams.

Another nice free-form faceted piece from material collected outside Felch, Mi. Under extreme pressure tremolite
can metamorphose into nephrite jade and this material reminds me a lot of the colors and patterns that I've seen in jade from
Wyoming. Approx. size: 34x22x14 Weight: 17.8 grams.

This beautiful pink tremolite comes from the same location in Felch as the green does, but it's a little harder
to find in gemmy pieces that are suitable for cutting. This is a fantastic piece displaying a great sparkling effect.
