New poster here, frequent lurker. Looking to buy a cushion cut for wife. She currently wears just a diamond band and I want to get something nice for Christmas close to her dream ring. I know she loves the Verragio Insignia setting so looking for a center stone now. My budget for the diamond only is 10-12K and will have it put in the Verragio setting. I know her dream is to have a 2 carat cushion cut so I want to get as close to that as possible. Her criteria and I quote, were, "Big, sparkly and eye clean". Can anyone here help me find the best/largest diamond for money? I don't really know which areas are best to sacrifice on in order to get the biggest stone that is still going to sparkle. Thanks.
