dazai osamu modelI'm Osamu Dazai! A genius novelist who appeared in this world like a comet!

It features a pattern inspired by Dazai's costume, and Nakaishi uses almandine garnet, which is close to the image color. The arm part incorporates a braided design reminiscent of the character's hairstyle, giving it a cute look.

Ryunosuke Akutagawa delHello, my name is Ryunosuke Akutagawa and I would like to ask for your help from now on.

"Gears" is also known as one of Akutagawa's masterpieces. Gears, which appear as an important motif in the work, are the main design, and smoky quartz is used to match the color of the costume. The Japanese name for the mysteriously colored smoky quartz is smoky quartz, which is perfect for Akutagawa, who is known for being a smoker.

The main motif is autumn leaves, which is also the pattern of Kyoka's haori. It is decorated with sky blue topaz and yellow sapphire, inspired by the color of Kyoka's kimono, which reflects her feelings for her master Momiji Ozaki.

An elaborate mechanism with rotating gears

Of the three parts, the two overlapping gears are designed to move like real gears. The people involved in the production are skilled Japanese craftsmen who know everything about precious metal processing, and each part is created one by one and completed by hand.

The diamond set in the center is of the highest quality

Diamonds have a value standard called 4C. Among these, the clarity (=transparency) that affects the beauty of a diamond is carefully selected from high-quality diamonds called INTERNALLY FLAWLESS, a class of diamonds that are rarely used in engagement rings.
Each large and small gear is set with a sapphire and a ruby. The large gear has a diamond in the center and 6 multi-colored sapphires around it, and the smaller gear has 7 brightly colored rubies.

Another gear connected by a chain is set with almandine garnet, London blue topaz, and rhodochrosite. These jewels were chosen from the image colors of Dazai, Akutagawa, and Izumi, and the combination of colorful jewels symbolizes the vivid literary world created by the different styles of works of these three great writers. Even though they are the same type of gemstone, no two are the same in the world, with subtle differences in color and shine, and they have a charm that is shared by humans living in this world.
This is authentic jewelry that only KARATZ, which handles jewelry from all over the world, can deliver.
