Fabricating a Platinum Ring - Part 7
Step 23
Using some left-over platinum stock the center line is being marked. By making two side by side lines, the jeweler can cut in between and thus cuts a straighter line
Step 24
Using a 3/0 saw blade, the cut is made from both ends, leaving a dedicated area in the center intact.
Step 25
Using a knife blade or a graver, both ends are spread apart.
Step 26
After the piece has been cut in the exact center, further precise cutting will create a key for assembly of the pieces into a head for setting the center stone.
