Overstock has this pair of 14k Gold 1/2-carat Diamond Solitaire Earrings for $239.99 for through 3/31 after this $30 off $250 coupon. The effective 12% off from the coupon creates the lowest price I've seen for these. Read the reviews: over 70 buyers rate them 4.6 of 5 and 96% would "recommend to a friend." Shipping is $2.95 and there is no sales tax (except UT, IN).
