You may not think of a department store, known mainly for clothing, as your first choice for jewelry but give it a look. My husband purchased a diamond channel-set platinum ring and white gold earrings for me at Macy's. The ring in the case just happened to fit me perfectly(a very small size that someone had special ordered and then changed their mind) so it seemed like a sign :) Both pieces were on sale plus the associate told us there was a coupon they could apply to it bringing the total down considerably. Now the earrings have had to be repaired because a couple of diamonds fell out. I guess that's a downside to buying machine set diamonds as opposed to hand set. However, other than that, I've been pleased with the pieces.
I've also purchased a couple of watches here at great clearance prices.
