This deal has ended.
Overstock has this pair of 14k Gold 1/2-carat Diamond Solitaire Earrings for $220.99 after a promotion for an extra 15% off all watches & jewelry (valid through 7/22). That combines with this $20 off $200 coupon (valid through 7/31) to reduce the price further to $200.99. The double discount creates the lowest price I've seen for these or any other 1/2 ct. earrings. Read the reviews: over 110 buyers rate them 4.6 of 5 and 92% would "recommend to a friend." Also, shipping is currently only $1 and there is no sales tax (except UT, IN).
