Made of silver 925 and brass, engraved with an original random pattern. The turquoise is natural Persian turquoise. It's a beautiful stone with a pale gradation. It's a bit hard to see in the photo, but it's shiny. Brass will maintain its gold color depending on how it's cared for. This is handmade, so there may be some imperfections, but I would be happy if you like it. The chain is a reference item and is not included.
