Here's a more detailed breakdown:
* French Polynesia (Tahiti): This is the primary source of high-quality black pearls. The black-lipped oyster, *Pinctada margaritifera*, thrives in the lagoons of these islands, producing pearls with a wide range of colors, including black, gray, green, and iridescent shades.
* Other areas (smaller quantities): Black pearls are also sometimes found in smaller quantities in:
* Cook Islands: Another island nation in the South Pacific.
* Micronesia: In some regions.
* Panama: Occasionally, though not in large commercial quantities.
* Philippines: Certain areas are known to produce South Sea Pearls which can include black pearls
The key is the presence of the black-lipped oyster, *Pinctada margaritifera*, and the environmental conditions that support its growth and pearl production. French Polynesia is the most successful area for cultivating these oysters and consistently producing high-quality black pearls.
Therefore, if someone is talking about genuine, high-quality black pearls, they are almost certainly referring to Tahitian pearls from French Polynesia.
