1.348 ct loose red coral from Kochi Prefecture
This is oxblood coral collected 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 oxblood coral was purchased directly from an oxblood coral dealer in Kochi Prefecture. *Although it may appear bright in the photos, the actual color is a deeper, richer red. Please enjoy the subtle color unique to oxblood coral.
This is oxblood coral from Kochi Prefecture, considered the top color among oxblood corals. Skilled craftsmen in Kochi Prefecture have carefully polished it into an oval cabochon, and its beautiful luster and deep red color are its charm.
