Great post! Thank you. Adding to the discussion, from Rubylane:

Vintage Chinese Carved Guri Lacquer Cinnabar Large Bead Necklace. Lacquer is applied in red and black colored layers largely on a wood core and carved in geometric or curved patterns so as to reveal different lacquer colors. Dates to 1940s -1950s (could be bit earlier). Necklace is 27 inches in length. It has no clasp; it needs to be tied on the back. Necklace was recently re-strung. There are 10 hand knotted beads with approx. diameter of 1 inches. Light surface wear.

(Per an Internet site, Guri is the Japanese term for this lacquer, Tixi is the Chinese term.)
