My husband would like to gift me my first pair of diamond studs for our 20 year anniversary. We are looking at 1.0 - 1.25 ctw. My husband liked the 1 ctw studs at Costco for $2500. They claim to be VS2 or better with I color. I read through quite a few threads here and it seems like most people recommendfor studs. I checked out their website and it looks like studs around 1 ctw would be about double the price. Is the quality of the studs that much better that its worth paying $5k. Does anyone have any experience with the diamond studs they sell at Costco? I want them to have a nice sparkle.
