We are a company located in Kobe, Japan, exporting Akoya Tahitian Blace and South Sea cultured pearls.

We Offer Genuine AAA


First of all, different from diamond, there are no generated grading standard for peals not only in Japan but also in the world.

Mikimoto which is the inventor of cultured pearl made AAA-A grading system.
And many of other suppliers follow the grading system that grades pearls as AAA, AA, or A.

But as mentioned above, this is not a generated standard, each suppliers decide "what should be AAA, AA, or A".

Sometimes we experience that AAA of company X is just AA of company Y.


By the way, Mikimoto's grading system is very strict.
As they are the original inventor of cultivating pearl, they can get almost all of the top quality pearls from many of farms.
In other words, pearl companies other than Mikimoto hardly get space to buy such top quality pearls.

Actually, many of pearl suppliers do not know this fact.

Therefore, even they believe they could buy "the top" quality, but in fact, those pearls are just leftovers after the actual top quality pearls got carried away.

Then many of AAA you can see are actually just AA, when we use Mikimoto's standard.

Truly top quality pearls are rare and precious, never sold at low prices. Mikimoto and only a few suppliers can get.

In Japan, we are one of such suppliers, and can supply at reasonal price because we are a small group company and do not use many amount of cost for running.

But as we mentioned above, the top quality pearls are not sold at normal price furthermore at low price because of the preciousness.

If you are looking for truly quality pearls, we are convinced we can help you.
