Identifying Jewelry Trademarks: Help with 'LC' Mark

Question
I have earrings with a round symbol the the letters LC after.Any idea what trademark or maker?

Answer
I'm sorry Bob I have never seen this mark before. There are Jewelers hallmark and trademark publications available on the web through a google search.
There also are trade mark publications in some Libraries.
Thanks for writing and good luck.
