This set of Malachite Bangles are Vintage,if not antique. One Measures 2.5 inside the center, the other measures 2.75 approximately in the center. They are both approximately .50 inch thick across. These bangles would fit a 7 inch wrist size. Please see photos for condition. There is some separation on the Malachite but no liftage. The Malachite is set on what appears to be brass. I would say that this set is in very good condition for their age.
