As pearl prices continue to rise, renewed attention is being paid to the asset value of pearl jewelry. Tieel Inc., which operates the specialized buying service ‘Omoio’, has strengthened its appraisal system for pearl jewelry, staffed by GIA-certified professionals, in response to the decreasing supply of Akoya pearls and changes in the brand jewelry market.
The pearl market has seen continuous price increases over the past several years. This is driven by a decrease in the supply of new pearls due to mass die-offs of Akoya oysters and a long-term decline in the number of domestic pearl farmers. Compounded by the weak yen and rising fuel and labor costs, the price of Japanese pearls has reportedly risen significantly compared to several years ago.
Against this backdrop, the prestigious pearl jewelry brand TASAKI revised the prices of some of its items in June 2026. The reason for the revision is attributed to the surge in raw material costs. Founded in 1954 as ‘Tasaki Shinju’, TASAKI is a brand that handles everything from pearl cultivation to processing, and its price revision coincides with the changes in the pearl market.
Pearls are gemstones that are often purchased once for ceremonial occasions and then left to ‘sleep’ in drawers or boxes for a long time. Many people hold the impression that ‘pearls are hard to value’.
However, in reality, even in the second-hand market, there are increasing opportunities for well-conditioned Akoya pearls and brand pearls to be properly evaluated. The unique luster and color of Akoya pearls are being reassessed. As the supply of new pearls tightens, demand for existing pearls in good condition is quietly rising.
On the other hand, the value of a pearl is not determined solely by its size but is evaluated based on multiple factors such as luster, nacre thickness, shape, and blemishes. Professional expertise is required to accurately determine value, creating an information gap.
Regardless of whether one intends to sell, knowing the current value of one’s pearls has become more meaningful than ever before.
At ‘Omoio’, appraisers certified by the Gemological Institute of America (GIA) are on staff, conducting appraisals based on gemological knowledge cultivated at the GIA. For pearls, whose value is being reassessed, the company has strengthened its system with the following:
– Professional pearl appraisal by GIA-certified holders, considering luster, nacre thickness, color, and shape.
– Market-based evaluation reflecting both domestic and international sales channels.
– Presentation of current value reflecting the rarity and popularity of brand pearls, including TASAKI.
Rather than simply calculating based on the weight of the metal setting, the system is designed to comprehensively assess the current value of pearl jewelry, taking into account quality, brand value, and market conditions.
The important thing is not to panic over price movements, but to correctly understand the current value of your own pearls. We will provide appraisals that you can be satisfied with, while respecting the memories of our customers.”
‘Omoio’ values the history of gemstones and jewelry and the stories of their owners, aiming to connect their value to the next owner through its buying service.
