Here’s what I have on zoisite.
ZOISITE: These long striated crystals are found in brown, blue,
green and white. Its primary area of impact is to stimulate the
root chakra. With better flow in this area, a person’s overall
energy level and adrenal balance are enhanced. Both the male and
female sexual organs are healthier and a fertility increase would
be natural. A pink variety with manganese is called Thulite. A
violet variety with chromium and spontium is called Tanzanite.
(Acts on the 1st chakra.)
