All natural peacock color 14k gold back, these are what make pearls so magical. The luster on these tahitians is out of the this world! The thick nacre proves they are high quality. Unfortunately due to their high prices only a handful of people ever own a pair. However, Aloha Pearls has tried its hardest to make these beauties more affordable than ever. If you can find a price lower than this we would like to know.
