Sustainability and traceability in marine cultured pearl production
Our main objective was to examine select sustain- ability questions in the context of pearl farming and investigate methods potentially useful in tracing pearls |
How do you tell if a black pearl is natural or cultured?
How are natural pearls identified? Natural pearls have a thicker nacre or “skin” when compared to cultured pearls.
When held against a concentrated light source, a pearl with a thick nacre will show concentric growth lines, where layer after layer of nacre was added over time as described above.What is a genuine cultured pearl?
Cultured pearls are grown in pearl farms, and are the direct result of human intervention.
The vast majority of pearls in the pearl/jewelry market are cultured pearls.
Cultured pearls may be bead nucleated, tissue nucleated or otherwise non-bead cultured, and they are produced in both saltwater and freshwater mollusks.As a matter of fact, according to the American Gem Society, most of the ocean's natural pearls have already been harvested by pearl divers.
Therefore, even though the quality of a cultured pearl may be the same as that of a natural pearl, the cultured version is generally much more affordable because of its rarity.
