Lamp Work Bead Necklace in Black and Brown Made in USA
I find that single beads like this are popular worn on a cord with two sliding knots. Casual and easy for those who really do not like to wear lots of jewelry but like hand made work.
The bead is also useful for a designer to use, take it off the cord and you already have two Gold Fill bead caps get you started.
The bead is 23 mm. Well annealed.
