This beautiful bracelet made based on Viking age archaeological finding. Arm ring made of brass. I currently have 2 bracelets done with diameters approximately: - 3" (7.5 cm). - 2 5/8" (6.6 cm). If you need different size, just message me when order. To find out which size will fit you just measure your hand in the widest spot. If you have any questions or would like to have similar bracelet made of different material: copper or silver (for higher price) just message me.
