Ring re-sizing service and size comparisons
Re-sizing rings
A regular service that we perform is the re-sizing of rings. This includes the release of rings that cannot be removed from the finger.
Here are two examples from our workshop
This is a 9ct gold ring with an oval cut blue topaz and a diamond surround. A customer purchased it from us but it needed to be sized up from K to M. You can see how Brent did it step by step progress in the pictures.
This is a 9ct gold wedding ring that had been cut. Brent soldered it back together at the new size and then finished it off with polishing.
