My friend has a diamond and platinum ring she obtained from her great
aunt’s estate (she was a retail jeweler). It is a very fine setting with a
large pear-shaped yellow diamond and three good sized round diamonds. When
she took it to a local jeweler for appraisal, they discovered a hallmark on
the bottom of the band on the outside. Under the microscope we could see it
is the profile of a dog’s head (German Shephard type), perhaps with its
tongue out. It’s the dog’s right side. The jeweler can’t find the source
and I was wondering if you could help us identify the jeweler. Thank you!
