Handmade. Natural beautiful coral faceted is tested by a jeweler but you can also check it yourself if it is real coral: when you rub it against your tooth the stone is rough like sand and if it is not real it is very smooth like glass or plastic. This is an old method of checking whether a coral, pearl or a natural stone. Necklace length: 47 cm / Diameter stones 8.0 mm Total weight: 33 grams Shipping registered.
