I purchased this from a shop that buys and sells antique items from overseas. It is a foreign-made product. I do not know the metal material. A gold-colored saxophone-shaped brooch with crystal stones, a unique design. Please understand that this is an antique item. Thank you for your understanding. It is small. I have used it once or twice. - Design: Saxophone-shaped brooch - Material: Gold-colored metal - Embellishment: With crystal stones - Style: Unique musical instrument motif - Use: Fashion accessory Thank you for looking.
