lost marquise dia platinum engagement ring

very special and sentimental ring lost this time last year on bus journey between Sligo and Dublin. I am still looking as I am heart broken that it had not turned up... It is a size J and the carat size and initials are on the inside that would make it unique to identify and prove ownership. discription: Metal - platinum Diamond - white two letters on inside of band the carat size is also on the inside band reward for ring if found
