unfortunately my costco doesn't stock tennis bracelets. I had to go to another location farther from us but they only had 3ctw with G color diamonds. Even with the smaller 3 ctw it still had a lot of sparkle. 5 and 8ctw are the more popular ones on the costco site as they have more reviews. But the 5 ctw at costco has 61 diamonds vs 5ctw at james allen with 49 both 7in.
