PEARLS

NIWAKA Pearl Evaluation

For the SHIROSUMIKA collection, NIWAKA uses high-quality Akoya pearls that require no color treatment. In order to carefully select extraordinary pearls, NIWAKA has established its own strict and objective evaluation criteria for a rigorous assessment of each pearl based on color, luster, surface quality, size and shape. After stringent examination, NIWAKA pearls are classified into five grades: Special, Special+, Superior, Superior+ and Superior++.

Special Grade

Special Grade

These pearls have an exquisite white hue that gives an impression of clarity and depth with a soft, translucent glow. They require no color treatment and are characterized by a high ranking in every category of NIWAKA’s pearl evaluation.

Special+ Grade

Special+ Grade

This grade is assigned to the small percentage of pearls that exhibit very subtle pink overtones without any additional color treatment. These pearls have a high ranking in every category of NIWAKA’s pearl evaluation, and the rare coloring makes them even more precious.

Superior / Superior+ / Superior++ Grades

Superior / Superior+ / Superior++ Grades

These magnificent pearls are of the highest quality, selected for their extraordinary beauty and rarity. Every pearl in the three Superior grades has a slightly pink hue, a particularly elegant shimmer and a powerful presence. These extremely rare treasures account for only 0.002% of pearls cultivated in Japan.

Pearl Size

Our pearls are available in four sizes: 7.0 mm, 7.5 mm, 8.0 mm and 8.5 mm. Larger Akoya pearls are rarer and therefore more valuable.

(Depending on the item, certain pearl sizes may not be available.)

Necklace Length

Necklaces are available in five lengths: 36 cm, 38 cm, 40 cm, 42 cm and 44 cm.

Necklace Clasp Types

The parallel line motif of the necklace clasp is inspired by the koshi latticework often present in the traditional architecture of Kyoto. The type of clasp differs depending on the grade of pearls used in the necklace.
