ABOUTAbout Mori Pearl

Philosophy:Basic philosophyPhilosophy

Our corporate philosophy is ``Creating dreams and joy through the beauty of pearls,'' and we have been dealing with pearls for 50 years. Until now, we have collected only the best products from all over the country on the stage of department stores and delivered them to consumers. However, from now on, it is natural for the quality to be good. We want everyone to smile. Although Mori Pearl does not culture pearls, we communicate the feelings of our creators to our customers and create and propose a life with pearls.

Policy: Direction Policy

Pearls are a gift from the sea. Because it is a treasure nurtured by nature, it must be sustainable. In order to deliver beautiful pearls to the future, we support activities that protect the rich natural environment.

As pearl professionals, we have established strict inspection standards. Pearls are one of the most delicate of gemstones. We check not only visually but also by light check, down to the nacreous layer and nucleus. We inspect every single piece of necklace.


We use six criteria for selecting pearls (cover, flaws, flaws, color, shape, and size), as well as standards for matching by pairing for necklaces and pairing for earrings.


Currently, various types of pearls are cultured using different mother oysters. They cannot be directly compared; each has its own characteristics. At Mori Pearl, we have established detailed selection criteria for each type based on our own experience.

Inspection TestInspection Test

A characteristic of Mori Pearl's inspection is that it does not rely too much on visual inspection. Pearls are designed for long life. In order to ensure long-term use, we use a special light to check for cracks and cracks in the core that cannot be seen with the naked eye, as well as disturbances in the mother-of-pearl layer. We prioritize quality and safety so that you can use our products with peace of mind by preventing future damage.


Because pearls are gemstones grown by nature, they are not all the same in size and shape. For those with high sphericity, Akoya pearls are matched with an error of 0.1 mm, and white and black pearls are matched with an error of 0.2 mm or more.

For necklaces, we carefully examine each of the 6 items and are conscious of the ``linkage'' that is suitable for the purpose. For basic formal necklaces, skilled craftsmen match them to the best of their ability, not only in terms of color and size, but also in the amount of small scratches and the strength and weakness of the fabric.


Beautiful to look at. Comfortable when worn. Our necklaces are assembled using original methods that have been carefully thought out based on our many years of experience and our unique perspective. If you tighten it too tightly, it may twist or float. If it is too loose, the pearls will move and the thread will break easily. We basically recommend regular thread changes, but we do our best to keep the thread in its best condition for as long as possible.
