I think the diamonds you are referring to are Rose cut. I may have
one or two around here in the size you need. If not, I can refer you
to a dealer in NYC who stocks them.
If you feel like taking a drive on Saturday, why don't you stop by
the gallery here in Frederick, and I'll try to match them up for
you. The foliage is at its PEAK this weekend, and I can get you a
great map of the Catoctins.
