These beads are big - the larger one is 1 1/4 inches long and 5/8 inches wide with a 3.5mm hole. The medium sized one is 1 inch by 1/2 inch. The smaller ones are just shy of 1 inch long and 3/8 inch across, 3mm hole. They are a vintage age (1970's?) and have a little patina. Great boho / tribal pendant / bracelet and earring set. They could also be used for macrame or anything else you dream up.
