I always loved and admired this kind of moon face cabochons. In former times, they were carved out of ivory which is, thank goodness!, forbidden nowadays. Yet the ones you can get nowadays are still made from animal bones. With this ring, you get the "animal friendly" alternative because, believe it or not, the moon face is made out of eco-friendly resin. So the "stone" is completely handmade - from mold making to polishing. This is why every little man in the moon will look slightly different:) It is set in a gold plated brass setting with open ring band. The ring's size is adjustable to any measurement, so it can be worn alternatively on different fingers, and it makes a great gift. Also works great as stacking ring. Water-resistant, non-allergenic and nickel free. Measurements: Its top size is approximately 0,6" (15 mm) Ring band is adjustable. The last picture shows the matching stud earrins which are available via https://www.etsy.com/de-en/listing/1399715920/ All my items are safely and nicely packed in elegant Villa Sorgenfrei gift boxes.
