Antique Japanese Meiji Era Natural Red Coral Ojime Bead

From a local estate with provenance dating back over 100 years, this is an antique mid Meiji era (c. 1890) all natural (undyed) re coral bead. Probably once used as an ojime (synch bead).

Measures 3/4" wide (18 mm). And weights 10 gm. Having been stored for over a century, it remains in very fine condition.
