These are handmade sterling silver sleeping beauty turquoise stud earrings made to order. These are my most popular earrings in my shop. They are cute little pretty blue stones. These are natural Sleeping Beauty Turquoise Cabochons that come from the famous mines of Globe, Arizona. This turquoise is noted for its solid, blue tone.I now offer another bezel.(silver around the stone). I have the plain bezel,which is in picture 1 and 2 and the serrated bezel in picture 3 and 4. So when ordering,pick which one you would like. They are 5mm stones and approximately 6mm overall. They have hypo-allergenic clear rubber backings.
