CityDeals has a Prized Pearls deal right now where you can get 4 sets of pearl earrings (post or drop earrings) for just $35. That deal is even better for a limited time using code: SUNNY20 for an extra 20% off! That means that you can get $150 worth of pearl earrings for only $28. Wow! That is over an 81% discount. Go here to grab the deal while the code is still working. These would be great for Mother's Day.
