I don’t make every ring size from 5-14 and all the half sizes for each opalescent inlay. The math does not add up to me. A customer looked at the rings I stocked and purchased a size I did not have. I ordered it as he left the store and deliver it today. Less than a week worked out this time. This is a size 12.5 with a 4 mm inlay channel and 8 mm overall width in titanium. The material is “Opal 75”.
