8.0-8.5 mm GIA Hanadama Akoya Pearl Necklace

This 8.5–8.5 mm hanadama akoya pearl necklace represents the very top range of what we offer in this classic size.

Hanadama is not a single grade, but a range of fine-quality akoya pearls. When we encounter strands that stand apart for their luster, surface quality, and overall balance, we submit them to the Gemological Institute of America for hanadama certification.

GIA applies a more stringent evaluation standard than the Pearl Science Laboratory of Japan. While many hanadama strands certified by PSL would not qualify under GIA’s criteria, any strand that earns GIA hanadama certification would meet or exceed PSL’s requirements.

The pearls in this necklace measure 8.0–8.5 mm and are carefully matched for brightness, shape, and consistency. The necklace is strung on twin silk to protect the strand over time. It is finished with a solid 14K gold clasp with a safety hook.

The standard version is finished with a solid 14K gold clasp with a safety hook. An optional 18K diamond clasp is also available, set with seven natural diamonds of VS1–G quality with a total weight of 0.21 carats.

This is a refined, understated hanadama strand for those who value precision, balance, and independent verification over marketing terms.
