For sale is one of the must unusual charms I've ever owned. It has a pretty and very tiny, prong set white sapphire set into a white gold tiny setting and it sits inside its original hinged, 10k white gold jewelry box. The base of the box measures just over 5/8" and it sits 3/8" high. It weighs 4.7 grams and is in great condition. I would assume that the original jump ring had the 10k hallmark, but it has been carefully acid tested to be at least 10k gold. The ring is secured inside the box and does not fall out.
