These settings measure 18mm at the outside rim (not including the prongs which measure 7mm.) The base of this version isn't flat. It is curved upward like a bowl to match the shape of an 18mm stone. You will receive six settings with prongs and dapt open backs for domed back stones which measure 18mm. These settings are oxidized sterling silver plated brass. An example of how you can add this style of setting to the openwork of a filigree or a stamping to create a unique setting is shown in the second photo provided by the late Willie Zuniga. Note the use of this setting in the pieces shown in the additional photos of finished work. Those items are shown to give you ideas but are not included. The front and back are shown. Made in the USA. #S193
