I purchased this brooch at a vintage shop during my trip to Europe. I believe the stone in the center is turquoise. Size: Approximately 4.5cm x 4.5cm As this is a used item, there may be minor scratches. Please judge from the photos. The condition is as shown in the photos. If you have any questions, I can add more photos, so please feel free to comment. *Please purchase after you are satisfied! Ships via Nekopos (domestic Japanese shipping service). Instant purchase is OK.
