When the bottom of a ring has become too thin from wear, we do what’s called a “half shank”. This is where we fabricate a matching thicker shank to replace the older worn out bottom half of the ring. When done right this extends the life of the ring and restores it to a like new condition.
The bottom of this 14 karat gold ring is way too thin from wear, it needs to be replaced.
A new gold shank has been fabricated to take the place of the worn out shank.
The worn out part of the ring has been removed to make way for the new thicker shank.
Firecoating, To prevent staining of the metal, a thin layer of boric acid is coated around the ring to keep oxygen in the air from reacting with the copper in the gold alloy during soldering.
