The size of a bead is expressed using the metric system. Throughout our site, we present the length of a bracelet or neclace in inches (in.) and the size of the bead in millimeters. We created this visual representation to help you get a better perspective.

Some basics
10 mm = 1 cm (centimeter)
1/4 in = 6.35 mm
1/2 in = 12.79 mm

The beads shown here are all made by Swarovski: cut crystal and pearls.
