I just received a platinum and diamond band I won on ebay. How can I tell if the diamonds 7 x .03 are single cut? When I look at them through the 10x loupe, there is a very simple facet pattern, not sure how to describe it, but far less facets than the same size melee in my Bev K rings. They sparkle like *crazy* although I think one might be chipped. I'm thinking they might be single cuts. Does it sound like it?
