This is carnelian in its natural form--no dyes, no attempts by man (or woman) to "improve" upon it. Chalcedony colored by iron oxides, creating a beautiful natural honey color, as a new crescent moon. Included with the pendant are a 16" 1 mm sterling silver snake chain and an 18" black silicone cord. The photos show both options, as well as a close-up of this beauty.
