My husband is gifting me diamond studs for our 20th wedding anniversary. I'm looking at a pair of 1 CTW studs from Whiteflash. There are so many choices and I'm a little overwhelmed...am I correct in assuming any pair of ACA studs from WF will have amazing sparkle? The pair I'm looking at are VS1, I color. Also I'm unsure of which prongs to choose for the setting. Martini vs. basket...which is best for 1 CTW size?
