The image featured here is actually a CAD CAM drawing (computer aided design) for computer aided manufacture.
The ring is made from two separate castings, the top plate with square and compass in oval frame can also be used for cufflinks tie tacks & earrings & the main body of the shank.
Once soldered together BY ME and hand finished the join is almost invisible.
This technique although time consuming, and therefore more expensive than one piece casting, has two advantages : Firstly the quality and detail are exceptional : Secondly I am able to make the rings in two colour combinations with Bi-colour and gold on silver if requested.
