The Petit signet ring is a perfect signet for the little finger. The sizes are small for that reason. Generally a 4 or 6 is for a woman's pinky finger and a 12 is for a man's pinky finger or a woman's ring finger. The rough surface gives it the Mediterranean and artisanal character. It is made entirely of 925 silver and available in three sizes. Silver 925.
