The average width of the bangle is 1/8″ (4 mm) in width. Dia Bangles come with a 1/2″ (12-13mm) gap. The sizes shown are the inside circumference including the 1/2″ (12-13 mm) gap. Although Dia Bangles are adjustable, I recommend ordering 1/2″ to 1″ above your usual bangle measurement size as they are meant to fit looser on the wrist than the usual round bangle would fit.
Not every Dia Bangle is individually photographed. The bangle you will receive will be very similar to the ones pictured but may differ slightly due to differences and variations during the fabrication process (hammering, patina application, etc).
