These bangles make the prettiest twinkling sound when you wear more than one at once. Each bangle is hand-forged in polished 14K gold from recycled sources. We never use hollow wire so our bangles are always sturdy and solid. Our bangles are available in three sizes: small (2.25" inner diameter), medium/average (2.5" inner diameter), and large (2.75" inner diameter). Measure the width of your closed fist, from your first pinky knuckle to your index finger knuckle to find out which diameter bangle will work best for you. Our stacking bangles are 1.6mm thick.
