Handmade sterling silver earrings Enigma with black plating and precious stones (zirconia) Enigma-HE-07-M. All Enigma jewelry are from sterling silver 925o. The specific jewel belongs to the Collection 2017 of Enigma. The plating on the silver jewel protects the metal from its natural tendency to blacken and keeps it shiny. There are five different platings in handmade jewelry Engima, platinum plating, gold plating, rose gold plating, black rhodium plating and white rhodium plating. The black and white rhodium platings are the most expensive and demand special crafting skills. In many objects, two or three different platings alternate and this is a key feature of the Enigma jewels, which creates sophisticated and original designs. Due to the fact that the item is handmade, there is a possibility of a small delay (2 or 3 days) depending on the workload of the Workshop.
