Nice chunky central bead measures 1" and graduate down nicely to 1/4". The 19" necklace is strung on gold-filled chain you will probably never need to restring. Their symmetry is just slightly off at the closure, (a bead or two more on one side than the other), but the wearer is the only one who will be able to detect this.
Art Deco French jet bead necklace with crystal drop worn by a Flapper. This faceted strand measures 44" end to end plus the drop about 1 1/8".
