Pearl Processing | Tensei Pearl
Our approach to processing
Luster and nacre over blemishes
At Tensei Pearl, we value luster and nacre more than natural blemishes. Of course, fewer blemishes are a good thing, but it is also true that many pearls on the market are simply free of blemishes and nothing more.
It is welcome that improved cultivation techniques now allow high-quality pearls to be grown in a short time. As a side effect, however, because the cultivation period is short, those pearls avoid the risk of blemishes but in return have thin nacre,
and the reality is that pearls without depth of color are on the market.
Processing
At Tensei Pearl, we value luster and nacre more than natural blemishes. We sort pearls by size and use, drill them, and then carry out a process called "shiminuki" (stain removal) to remove impurities inside the nacre. Pearls that have gone through only this process are sold as natural color pearls.
After that, the color tone of the pearls is adjusted with a technique called "chōshoku" (color toning). Through further sorting by luster, nacre, color and degree of blemishes, the pearls are divided into those for rings, matched pairs for earrings, half-drilled pearls for pendants and the like, and fully drilled pearls for necklaces, and then we design each product.
Craft that brings out individuality
We evaluate pearls that have slowly developed their individuality in the sea for about two years from many angles, and find the best design and setting for each.
Then, picturing the customer who will wear it, we assemble each piece with heart.
Tensei Pearl Quality Standards
Quality standards for necklaces include luster, nacre, color, blemishes, shape and matching. We do not sell any necklace that does not meet our own standards in every one of these points. So that you can wear our pearls with peace of mind for many years, we sort and process them with the greatest care.
