~ "Bungo and Alchemist" Writer's Ring Akutagawa Ryunosuke Model ~

"Gears" is known as one of Akutagawa's masterpieces. Gears, which appear as an important motif in the work, are used as the main design, and smoky quartz, which matches the color of his costume, is used. The Japanese name for smoky quartz is smoke crystal, and the mysterious color of the stone is perfect for Akutagawa, who was known to be a heavy smoker.
The blue ornament on the loop tie worn by Akutagawa is made using the gemstone London blue topaz. Its high transparency and vivid blue color captivate the viewer.
