My understanding is that most of the rainbow moonstone has been mined
out. My long time, major source for the material is only able to get
small stuff these days and she’s pretty up front about what’s going
on out there. There is blue sheen moonstone available these days, but
unless it’s older stock, I don’t think you’re going to find a lot of
true rainbow material in larger sizes. And no, I won’t sell any of
the pieces of my wife’s collection to you!
