I ordered a simple 4 prong solitaire last year in 1.5 ct to wear around and see how I liked the size. The stone was so glassy and unflattering that I immediately bought a OEC CZ off eBay and a white gold setting to simulate what I was after instead. The prongs on the emitations ring were big and unseemly, the "silver" was very unrealistic, and the stone was homely.
I've since ordered 8 other rings from Berricle and been so pleased with each and every one. If the one I ordered from emitations was a clue as to what their quality is like, I'd never go back. YMMV quite a lot, though, as I've seen some very pleased reviews for emitations.
