had to copy an existing ring, no time to cad it, so handmade. about 6 hours all up..
I will not see this finished, it gets the halo set, then the four prongs dropped in..
1: Forging the Shank. The image below represents the raw beam (top) rolled down to the right thickness (middle) then rolled flat to around 0.3mm narrower than the shank needs to be. (bottom). This is then annealed then bent round (far bottom) and soldered. The shank is usually easier to make in platinum as you can fuse it, as opposed to white gold which is soldered and leave a join. (i hate joins...)
The shank is split inwards at the joint and then along the shank either side of that split. These areas will be bent upwards to make the shoulders.
3: The basket. This section is made from leftover beam, rolled sideways to give me a flat metal area around 20% wider than my diameter of my head and 0.2mm thicker than my basket needs to be.
This then gets punched round and folded inwards to the correct diameter leaving the correct size hemisphere.
4: the head. This is also pierced from rolled beam, hammered down with a big hammer to work harden the metal (tiny beads will be used in setting, tiny beads want resilient metal.) I dome the metal slightly to represent the stone angle on the Halo and then drill out the centre stone section.
