I just realised that Chris is "new.com.tech" on ebay (duh, should have realised long before), which means I bought my first loose cz from him in 2004. It was a marquise cut that I put into a ring and wore daily for 2+ years, I slept with it on, showered with it on etc. and even now it looks like new, so you can order without fear, the stones are top notch.
