I have a piece of Csarite. It's one carat and in a cluster of very good zircons. There is a definite and very noticeable colour shift in the Csarite. I get the deep pinks red and greens.
I've got a Csarite ring, the stone is about a carat with two small diamonds, one each side. I've noticed flashes of reds and greens from the Csarite stone.
A family member has a gorgeous heart cut stone (about 1ct in size) - and it has very noticeable colour change in normal daylight - from light pistachio green, to golden brown, to reddish-pink.
