The latest information on pearl farming in Tahiti

Conducted under the Ameligen scientific program with Criobe, private stakeholders, and local authorities, these DRM-funded studies provide crucial insights into improving pearl quality while reducing production volumes.

The Genetics of Color: Yellow, Green & Red

The March 15th study decoded the genetic basis of pearl coloration by analyzing pigments in donor oyster shells. Key findings:

7 genes linked to yellow shells

19 genes for green shells

24 genes for red shells

These base colors—when combined with black or albino nacre—directly determine a pearl's final shade. This breakthrough could enable more consistent color production, enhancing market value.

Depth as a Color Amplifier

The March 19th study revealed how environmental factors, particularly farming depth, intensify hues. Researchers observed:

Epigenetic modifications in deep-water oysters

Darker pearls with richer luster (highly prized by buyers)

Industry Implications

These discoveries allow:
✔️ Precision control of cultivation conditions
✔️ Strategic repositioning in global markets
✔️ Reduced production waste


For a sector still recovering from pandemic-related export declines, this research lights the way toward sustainable revitalization of Polynesia's pearl industry.

The administrative court recently examined a claim by Toanui Pearls, whose 14,175 pearls were destroyed in March 2017—just before new legislation authorized their commercialization.

This case mirrors January's ruling that ordered the government to pay 30 million Fcfp in compensation after destroying over 120,000 pearls previously deemed unsellable. Both judgments found the destruction orders lacked legal basis.

While Toanui Pearls seeks 14 million Fcfp in damages, the court's rapporteur suggested 7.5 million Fcfp as appropriate compensation, noting the pearls held verifiable market value once commercialization became permitted.

A final ruling is expected by March 16.

The repeated cases highlight growing legal uncertainty for pearl industry professionals, compounding pressures on a sector already weakened by years of economic challenges.
