This is an exquisite and older necklace made of graduated genuine natural Baltic amber beads, egg yolk, butterscotch, and possibly one cherry.
The clasp is marked 1/20 12K GF. The necklace weighs 51 grams. The largest bead in the center of the neck measures 1/2" by 5/8". The beads are round to slightly flattened rounded.
There are no knots between the beads so slight wear is showing here and there. A few ever so slight nicks can be seen using a powerful loupe. The necklace measures 22 1/2" long.
