-History and Details- Japanese Akoya Pearls: History and Value The history of Japanese Akoya pearls began in 1893 when Kokichi Mikimoto established the world's first cultured pearl technology. Developing primarily around Ago Bay in Mie Prefecture, Japan became known worldwide as a pioneer in the cultured pearl industry. The value of Akoya pearls lies in their distinctive beautiful luster (teri). The deep radiance created by thin, uniformly layered nacre and subtle colors ranging from cream to pink and silver are characteristic features. Sizes of 6-8mm are most common, with perfectly round, flawless top-grade specimens being extremely rare. Their rarity has increased due to extended cultivation periods (2-3 years), rising water temperatures from climate change, disease outbreaks, and declining numbers of skilled technicians. Recent production decreases have also driven up their value. The reasons for their global trend include growing interest in sustainability, appreciation for Japanese craftsmanship, and a renaissance in classic jewelry. Particularly in Western luxury jewelry markets, Japanese Akoya pearls are highly valued for their quality and reliability, attracting attention as investment pieces. Their natural beauty and rarity align perfectly with contemporary values. -Condition- This pearl necklace was manufactured and sold likely several decades ago. It features the distinctive luster and nacre characteristic of pearls, with a refined, understated glow. While the color has changed over the years, this can also be considered part of its unique character. There are some signs of wear and minor scratches, but these are not noticeable at a conversational distance. The clasp uses a traditional SILVER metal fitting. As there are no cushions between the pearls, it is prone to accumulating dirt. We hope you will enjoy these beautiful Japanese pearls. - Shipping method- The lot will be carefully packaged and sent by DHL or FedEx depend on the situation.
