Thulite Rough
Thulite is the pink form of zoisite. Tanzanite
is also in the zoisite familiy. Norwegian Thulite is a great stone if you
want a pretty mottled pink. Thulite from eastern Washington
has attractive light pink spots contrasting with black. We've found that Thulite
polishes best with diamond. Thulite will also polish with tin oxide and green
rouge (Zam), but does have the potential for some undercutting. Mohs
hardness is 6 to 6.5.
