gold into onyx on s gents ring. Any advice would be appreciated.

  1. cut a groove with a reverse lip into stone (mouth of groove is
    wider than bottom)

  2. make a 24k wire with diameter just about 0.0002"’ wider than the

  3. burnish wire into groove

  4. finish with “hammer set” handpiece if needed

  5. voila

with stones that are weak in tension (onyx) you may have to compress
it, with a clamp, before you do the setting, to prevent splitting.

suggest trying a few attempts in a practice piece.
