Hanadama (Flower Pearl) represents the highest grade of Japanese Akoya pearls. Only pearls that meet the strict criteria set by Japan’s leading pearl grading laboratories, such as the Pearl Science Laboratory and the Pearl Research Laboratory, receive this title. These pearls stand out for their exceptional nacre thickness, brilliant luster (the aurora effect), and minimal surface imperfections, making them the finest of the harvest.

While both are high-quality, true Hanadama pearls undergo strict certification and must achieve the highest possible rank across all criteria: exceptionally thick nacre, brilliant luster, a near-flawless surface, and perfectly uniform shape. The aurora effect, a mirror-like reflection, is a key feature of Hanadama pearls and is rigorously verified with gemological equipment. In contrast, AAA is a seller-graded term without the same rigorous testing or certification.

Yes, every Hanadama pearl necklace, earring, or ring from WSP comes with an official certificate from Japan’s top pearl grading laboratories, either the Pearl Science Laboratory (PSL) or the Pearl Research Laboratory. This certificate verifies the pearl’s authenticity, nacre thickness, and Aurora Hanadama status, ensuring you receive genuine, top-quality Japanese pearls.

Nacre thickness is vital for two main reasons: longevity and luster. Thicker nacre creates a deep, radiant glow with pink and green overtones, which thin-nacre pearls lack. It also ensures the pearls resist degradation over time, maintaining their breathtaking beauty and rich color for generations without fading or losing their brilliance.

Pearls are organic gems, so it’s important to care for them properly. After wearing, gently wipe your jewelry with a soft, dry cloth to remove body oils. Avoid contact with perfumes, hairsprays, or cosmetics, as these can damage the pearls. For storage, keep your Hanadama jewelry separate from other gemstones (such as diamonds) to prevent scratches and preserve its pristine surface.
