I know there's a really nice grey Zoisite/Unheated Tanzanite, its on the 'bistro and it just dropped in price. Its been recut by Dan Stair. I hear the seller is a really great guy to work with too! He also has a 1ct Grey Spinel as well, its on his eBay page for $25.
They usually have a secondary. I have a grey-grape, precision cut. I call it frosted grape. It is square, scissors-cut. Really pretty. I have to go to work to measure/weight it, but each size approx 8mm. Just from my memory.
