scale hardness = 6-7

According to June Culp Zeitner, Thulite has a hardness of 6.5… I
would also imagine there are different grades of - “Thulite” -
slabbed material, which would slightly vary in hardness, according to
the materials overall purity…

Cathy- Hardness of thulite is 6.5. Thulite is a pink or rose variety
of zoisite, first found in Norway near a place called Thule. Also
found in Western Australia and South America. In the US, a rich
rose-colored thulite occurs near Pilar, New Mexico. (from: Zeitner:
GEM & LAPIDARY MATERIALS, 1996 & Schumann:
GEMSTONES OF THE WORLD, 1977.) -Anita Cluett

Kathy, The hardness of your pretty pink stone is 6-7. As some may not
know, it’s a variety of the mineral zoisite–the better known variety
being tanzanite, which I always thought should be called “heat-treated
brown zoisite,” which nearly all of it has been. Another beautiful
variety is “ruby in zoisite,” in which the rubies contrast with a
beautiful green zoisite. But then, I’m sure you knew all this.

Cathy, I don’t know the technical details on thulite, but I have cut
it and it’s pretty soft, but not fragile. It doesn’t break, crack, or
flake from normal handling but it would crumble if you hit it hard
enough. I wouldn’t put it in a ring but a pendant or earrings would
work. It’s a pretty pink and green…like a watered down version of
ruby and zoisite. Have fun with it!
