This is only the pendant top of an apple coral. The necklace is not included. The diameter is about 11mm or 12mm. This apple coral has a light color and looks just like a real apple fruit. There are also yellow parts. You can put it on a slightly longer chain, or wear it short as a choker. The bale is regular rhodium plating, but it is a new, unused item, so it is in very beautiful condition.
