Four chalcedony blue vintage buttons with opal glass cabochons and rhinestones, approx. 27 mm

Set consisting of four high-qualityclothing vintage buttons from a business liquidation of the Neugablonz jewellery industry. The buttons probably date from the 60s or 70s of the last century. They are unused and undamaged, but some may have a hint of patina. As I unfortunately only have four pieces in this colour, they are being offered together.
Care tip:
Buttons that are set with pearls, glass crystals or gemstones of any kind should never be washed in the washing machine, as this can cause considerable damage to the stones. Please wash the corresponding garments by hand with a mild detergent or separate the buttons before washing.
