Pendant has pink carnelian and amethyst stones and does have a maker's mark. I cannot read what it is due to wear. I have had this for about twenty years and have worn many times. The necklace itself is not silver but the pendant may be. Pendant is about an inch high and a half inch wide. It is a very pretty piece of jewelry but I have stopped wearing most of my jewelry and now am picking out pieces that I wear consistently. Hoping to find this a good home. Pickup in Ladysmith or Bowling Green. Cash only.
