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.
