[ 海の宝石 - Jewel of the Sea ]

A hidden glimmer, carried ashore by the tide

Sizing

Gem set: 30mm x 20mm

Material

13–16mm AAA Baroque Pearls
Selected from AAA grade pearls, each baroque form carries natural variation in shape and luster. No two are identical—each defined by its own surface, depth, and quiet irregularity.

 

Japanese Abalone Mother of Pearl
Sourced from the coastal waters of Mie Prefecture, each piece of abalone mother of pearl displays naturally shifting iridescence in shades of blue, green, and silver.

 

Hand-Applied Enamel
Applied in deep iridescent tones, the enamel is finished with a smooth, reflective surface that shifts between blue, green, and charcoal under light.

How to wear

Worn close to the body, where movement reveals subtle shifts in light and form.

Perfection was never the pursuit.
Pearls form slowly —
 layer by layer, shaped through time, patience,
 and the quiet rhythm of nature.

Gemstones carry their own journey,
 shaped by the earth and revealed through light.
At Aiko Tanaka, we believe jewelry should hold that same spirit.

 

Pieces where pearl and stone meet in balance —
 not made simply to be worn,
 but to be lived with.
