Commitment to processing
Teri(shine）and Maki(thickness) rather than blemishes
We place more importance on Teri(luster) and Maki(nacre thickness) than on natural blemishes created naturally. Of course, less blemishes are a good thing, but it is also true that there are pearls on the market that just don't have any blemishes.
The fact that the improvement in cultivation technology has made it possible to cultivate high quality pearls in a short period of time is a great blessing, but the downside is that the short period of cultivation has prevented the risk of scarring, and as a result, thinly sown, unattractive pearls are now on the market.
Processing Process
For natural pearls, we place more importance on Teri and Maki than natural blemishes. After selecting pearls according to size and use, and drilling, we perform a process called stain removal, which removes impurities from the pearl layer. Those that have undergone this process alone are sold as atonal pearls.
The pearls are then adjusted in color by a technique called tinting. We design products according to the degree of tying, winding, color, and scratches, and classify them into single-hole processing for rings, pearls for earrings, pendants, and double-hole processing for necklaces.
Make the most of one's personality
We evaluate the pearls from various angles to find the most suitable design and setting after carefully cultivating their individuality in the sea for about two years.
We then put each piece together with all of our heart while imagining the customer wearing it.
Quality standards for Tensei Pearl
The quality standard for necklaces is based on the following elements: Teri, Maki, Color, Blemish, Shape, and Phase, but we do not sell necklaces that do not meet our own standards for all of these elements. We select and process pearls with the utmost care so that our customers can use them for a long time with peace of mind.
