9.5-10.0 mm White Hanadama Akoya Pearl Necklace

This 9.5–10.0 mm Hanadama Akoya pearl necklace is an exceptional example of certified Akoya quality, featuring bright luster, excellent roundness, and smooth surfaces throughout. It meets the highest standards set by the Pearl Science Laboratory and includes full Hanadama certification.

Hanadama is the top designation of Akoya pearl quality, awarded to strands that meet strict criteria for nacre thickness, surface cleanliness, and luster. Each necklace includes a certificate from the Pearl Science Laboratory in Japan verifying its Hanadama status.

With pearls ranging from 9.5 to 10.0 mm, this strand represents the upper limit of Akoya pearl sizes and is a rare find at this level of quality. Its refined beauty and timeless appeal make it an heirloom-worthy piece.

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.
