Silver edged cuffl-inks are just a great gift. Made out of fossils all very different and natural one-offs. These ammonites are sourced from Madagascar, and are re-knowned for their vibrancy of colour. I hand pick each set with my husband in mind and he is really fussy. I have sold these for all age ranges from a Bar Mitzvah gift to a 60 birthday present. Something to interest someone interesting. Boys any age seem to retain their love of dinosaurs and anything jurassic.
