Semi-mount marked DAT

Jewelry Discussion
1

I need to replace a 14k white gold (rhodium plated) semi-mount that
took a 10x8 main stone, and has 36 pts. of diamonds in 3 pts. around
the mounting. The original piece was stamped DAT. Does anyone
recognize this mark? I would like to track down the manufacturer.
Any help would be greatly appreciated since I all but destroyed the
original and need to replace it for a good customer.

You can reply directly to worldofopal@aol.com,
thanks. Dan

Jeweler’s Circular-Keystone magazine published a paperback “Brand
Name and Trademark Guide.” I don’t know if it is still available or
in print. I have only an OLD edition (1978,) and there is no DAT in
it. A later edition might have it.
