I've had all of these for awhile - 2 years for the vintage early 20th century Mississippi river mussel shell shoe buttons, probably 8 years for the old black coral with silver color "nailheads" and possibly Yemeni silver beads which both came via Yemen with Abdul Touray. This necklace is full of texture and pattern and really feels neat. I think I'll like wearing it. Thank you to David for the great images.
