lost blue jewelry brooch on 17 of July in Dublin (possibly airport or taxi)

the brooch has different shade of blue stones and few whites, a friend of mine described it as an "owl". We arrived to Dublin from Helsinki on Sunday morning flight and took a taxi to downtown Dublin (Ormond Quay Lower) had breakfast at Mochaland Cafe and after leaving there noticed it was lost. It is not really valuable, but has sentimental value.
