Identifying a Ring Hallmark: Help with 'LAT 50 CO' and 'S'

Question
Hello, I live in the U.K., but when we were in New York my husband bought me beautiful ring.  It has 3 diamonds and they are set in white metal.  I cannot make out the hallmark properly, but I can see "LAT 50 CO" and what looks like fancy S.  Any ideas?  Thanks Jane

Answer
Thanks for writing Jane,

I'm not familliar with this hallmark. Where the ring ws purchased new from the jeweler. Contact the jeweler that sold it to you.
There is a good chance they will know all about this ring.

Hallmarks are like initials on a work of Art.
Unless it is a popular manufacture they are hard to trace.
