They weigh about 6 grams each, they are 19 mm in length, smaller top of bead 10mm in width gradually increasing to 15mm at the largest point on the bottom. This gives you that pear shape overall.
They have a great shine so they will add great character to any design piece. Pictures are actual beads that will be shipped to you. For a size reference please see the beads sitting on a quarter. Great size!
