Marque Cut Platinum engagement ring lost Febuary 2012

Marque Cut Platinum engagement ring Size J. Clarity is very good so the diamond is bright and clear in colour the shank is approx 2mm in width and come up into a thinner band to meet the diamond. With initials and .33 engraved on the inside of the shank ring. This graceful marquise cut is classically claw-set, and mounted on an attractive shank. the last two images are a close match to the actual ring. Lost on bus route from Sligo to Dublin in Febuary of 2012 - any help in finding would be rewarded... from a broken hearted lady desperate to find her treasured ring :'(
