18K YG CARTIER Italy Dog Brooch Revolving Head Onyx & Diamond Collar 9.8g, c1970This is a great CARTIER piece from the 1970's because dog's are a (wo)men's best friend! The head and collar can articulate on their axis and the eyes & nose are cabochon black onyx gemstones with the collar made out of platinum, 8 single cut round diamonds are set in a row, weighing approx. .12tcw. This Cartier brooch is stamped "Cartier" & "Italy" and has other numeric marking somewhat hard to decipher, but looks to be "3660" & "18CT"
