Graduated 18" Bluish White Angelite Bead Necklace with 14K Gold Lobster Clasp

May I offer this lovely vintage 18" graduated bead (6.5mm to 16.5mm) necklace that I believe is Angelite; if I'm wrong, then just call the stones a light bluish white Agate. Still strung on string with no knots between the beads, the lobster catch at the back is 14K White Gold (hallmarked as pictured). While the string appears to be strong, I would suggest a restringing with knots between each bead; of course, you'll get a longer necklace but you can also remove some beads to keep the length at 18". Lovely condition with no problems I can spot.
