AAAA quality pearls represent only 2.5% of any given annual pearl harvest. Furthermore, large black pearls in this quality represent an even smaller percentage. This pearl necklace represents the highest quality in every category. Each pearl is a rarity in itself, representing the highest quality available anywhere. When it comes to pearls with the most variation and uniqueness in color, Tahitian South Sea pearls win the prize by far. All of these massive black pearls are AAAA in quality with a spectacular overtone and a "Superior" grade luster.
