Irish enamel pendant modern maker ID

[muraille]

Just in case this is a famous maker (!), I'm asking if anyone knows this mark. Unfortunately it's partially erased but it seems to me the initials are IMS.

Found out from Ireland that the maker is John Michael Clarke, Pouldar Design, no longer in business. Hope this helps someone else another time!
