On Gibson® Les Paul®, carved top guitars the bottoms of the rings need a concave radius of about a 15". I'm happy to do this for you but it might not match your guitar exactly. Other models have a shallower curvature which will have to be determined
Ebony pickup rings are available as a special order. Because of the inherent instability and brittle nature of ebony these rings are extremely delicate. It is recommended that they be installed by a qualified repair person. Pickup rings are not waranteed against breakage due to over-tightened mounting screws or mis-aligned holes.
