About the pigment of pearls

 The color of the pearls cannot be known until the time of harvest.

Based on the results of the mother and cell pearl oyster of the previous year, we select the pearl oyster that are likely to produce white pearls and cultivate them.

 Because pearls are formed by the components of the pearl oyster, the color that appears inside the pearl oyster is reflected in the color of the pearl, giving it a beautiful luster.

Interference colors and Real colors

 Interference color refers to the color at the center of the pearl and is divided into pink and green. In general, the thicker the sill and the more taut it is, the darker the interference color will be.


 The real color refers to the color around the core. Atoning colors become white, and toning colors become pink, and this combination gives you a variety of looks.


 Also, depending on the clarity of the pearl layer, creamy pearls with a yellow tint will appear.

 In general, most pearls have been subjected to a treatment called "Cho-shoku". Cho-syoku is the process of restoring the color after removing the dirt between the layers of pearls. By tinting, the real color becomes pinkish. The surface is not dyed, but the inside of the pearl layer is treated, so the color of the surface does not come off.

 It is not that Cho-syoku produces Teri, and it is not a process to make a poor pearl beautiful by Cho-syoku.  Please think of it as a treatment that maximizes the original beauty of pearls.

 On the other hand, "Mucho-syoku" refers to a pearl that has only removed the dirt from the pearl layer.  If the pearl layer is transparent and beautiful without any coloring, it is processed into a product as it is. In this case, the rial color will be white.

About Renso

 The term "Renso" refers to the way pearls are aligned when they are assembled into a necklace. Each pearl has its own personality, so they may look the same but are not exactly the same in color. We assemble the pieces, taking into account the gradation of the shape and size of the pieces.

 A necklace with a good Renso will create a sense of unity and look more beautiful. On the other hand, if the Renso is not good, there is a high possibility of unevenness in size and color over time.
