Kochi Prefecture Natural Red Coral, 16.659 ct, Branch (Raw Material)
This is oxblood coral harvested off the coast of Kochi Prefecture, one of Japan's leading coral-producing regions. Its deep, rich red color is highly prized among all types of coral, which is why it is called "oxblood." This is an old stock rough purchased directly from a Kochi Prefecture oxblood coral dealer. This rough type utilizes the natural branch-like shape as is. Each unique form is a beautiful creation born from nature over a long period of time. The surface has a lustrous sheen, combining a smooth texture with a powerful presence.
*The color may appear brighter in photos, but it is actually a deeper, richer red. Please enjoy the subdued hue characteristic of oxblood coral.
