Leaf ring with prong stone setting and openwork.the file already has holes and openwork in the leaves, however i left two different shanks:

• one with openwork with the middle part full for marks and laser engravings.
• one without openworkThere's two STL files of the ring, one with the openwork shank and another without it. Theres an editable .3DM rhinoceros 7 file, if you buy it and need a previous rhino version i'll save it for you.
