Perhaps it’s MANY years experience in this ‘biz.’ Or, perhaps I’m
just ‘blowing my own horn.’ But, I find it is usually easy to
recognize g and g doublets. I’ve seen a LOT of them over the years,
and they’re pretty distinctive to me.
A friend/client brought in an heirloom ring last week for repair,
and I told her "I think the stone is an old-fashioned g-g doublet."
When I louped it, I confirmed it. Any other opinions on this subject?
