A best bet is the .25-tcw Diamond Heart Link Bracelet (pictured) for $42. After applying your unique gift certificate code, it falls to $17. (Enter the code in the "certificate" box during checkout; it is separate from the coupon box.) With free shipping, that's $178 off list and the lowest total price we could find. It features 24 round diamonds (H-I color, I1-I2 clarity) set in sterling silver.
