I've always been disappointed by any baguette cut eek pieces I've ordered. Not sure of the technicalities of the cut but they fall flat to my mind.
I have an eternity type eek ring with alternate round and horizontally set double baguettes and they work very well in that. It was one of the first pieces I bought - part of the Epiphany range I think - and it's still looking good.
QVC seem to rhodium plate most of their silver these days so appear to have dropped the Epiphany range.
I'm very confused - the full description is on the website for the Kollur pieces now and they call it both "simulated green Kollur diamonds" and "simulated peridots". I'm a massive fan of peridots - I love them more than any other gemstone - but it's the first time I've ever known them to be described as "green diamonds".
