Edison Pearl
Edison Pearl: The Modern Marvel of Cultured Pearls
Named in homage to Thomas Edison’s famed declaration that “two things cannot be made in the laboratory: pearls and diamonds,” the Edison Pearl represents a groundbreaking achievement in pearl cultivation, bridging human ingenuity with nature’s artistry. As a premium category of freshwater nucleated pearls, Edison Pearls redefine industry standards by combining the scalability of freshwater farming with the aesthetic qualities traditionally associated with rare marine pearls.
Developed through advanced bead-nucleation technology, these pearls are cultivated in freshwater mussels (Hyriopsis Cumingii) over 3–5 years, achieving remarkable sizes of 9–20mm (averaging 11–12mm) with a lustrous nacre thickness of ~2mm—comparable to South Sea pearls. What sets them apart is their unparalleled color spectrum, offering 8+ stable hues, including exclusive metallic tones like Ultra Violet, Gold, and Bronze, which remain unattainable in saltwater varieties.
For wholesalers and designers, Edison Pearls offer a strategic advantage: marine-grade elegance at freshwater accessibility, backed by GIA-recognized luster (90–100 GU) and defect rates below 5%. This fusion of science and nature positions Edison Pearls as the definitive choice for luxury jewelry that balances opulence, innovation, and value.
