I'm looking for assistance in identifying a designer of two beautiful diamond Calla Lily pieces, one a brooch & the other a ring. Both are by a designer commissioned through Franklin Mint in the mid 1980's. It's of conjoined, stylized letters within a downward pointing triangle. I feel like I've seen this mark on other non-Franklin Mint pieces but am having difficulty remembering where I saw it! I've only posted the the marking on the brooch as it is more clear than the ring.
Any help is greatly appreciated!
