9.5-10.0 mm White Hanadama Akoya Pearl Necklace

This 9.5–10.0 mm Hanadama Akoya pearl necklace stands at the very top of the Hanadama range, with exceptional luster, reflectivity, and surface quality. While not officially certified as Tennyo, this strand approaches that level in appearance and presence, offering a rare opportunity to own one of the finest Hanadama strands available.

Hanadama is the highest designation of Akoya pearl quality, certified by the Pearl Science Laboratory in Japan. Each necklace comes with a PSL certificate verifying its Hanadama status and confirming it meets strict standards for nacre thickness, luster, and surface quality.

Akoya pearls of this size—especially with this level of luster—are extraordinarily rare. Measuring 9.5–10.0 mm, this necklace is among the largest and most refined Akoya strands produced today.

The necklace measures approximately 18 inches and will arrive hand-knotted on twin silk and finished with your choice of clasp. A full Hanadama certification from the Pearl Science Laboratory in Tokyo is included with your strand.

While the strand cannot be lengthened, we are happy to accommodate custom shortening. If you prefer a closer fit, we can remove a few pearls and include them with your order—or use them to create a matching pair of earrings. We’re here to help you tailor the piece to your style.
