I purchased this online, and the product description stated it was 18K gold, but there is no marking on the item itself. I bought it to wear for work and have tried it on. It sparkles and I really like it, but I can't wear it to work, so I am selling it. Please only proceed with the transaction if you understand this. Material: Iron Details: Rhinestones Season: Daily Elements: Rhinestones Style: Casual Gender: Women's Style Type: Pendant Necklace
