Sterling Silver Bali Bead Cap measures approximately 5.5 - 6mm x 3mm. Check out the companion Bead 23 and Bead 24 in 6mm and 8mm for a great set! These give a very nice "victorian" sort of look to a piece.. I love them!
Inset picture shows the caps snuggling Swarovski 6mm Capri Blue crystals, with 4mm crystals on each side. If you click that picture, it will show you a magnified view.
