Grading:
We do not provide grading of the pearl.

We don't have grading scale like AAA, AA in Japan.

We don't write how the luster and blemishes are because that caused a problem as seller and buyer have different point of view for scaling.

Please see the photos for the luster and blemishes.
You can magnify the photos.

Stringing:
We do not string or add clasp to the pearl.
Please see the answer to the question: Do we make jewelries, string necklaces or bracelets, or drill holes?

We write "natural color" for natural color corals.
We write "colored" for dyed bamboo corals.

Basically our precious corals are natural color.

Almost 100% of Akoya Pearls undergo bleaching procedure to remove blemishes. However, bleaching also affects the original pink overtone of White Akoya Pearls that gives their beauty. Most White Akoya Pearls are tinted to restore their natural original pink overtone after bleaching.
-We do not mention about this enhancement on the description of white, cream, yellow Akoya pearls as it is common and accepted in pearl industry.

For non-color enhanced Akoya Pearls of all colors, we write "Natural color".

We write "colored" for color-enhanced blue/silver, gray, black/peacock Akoya pearls.
