Vintage Swarovski decorative buttons. These are gorgeous buttons with a Madeira Topaz Rivoli in the center, surrounded by crystal accents. The parts are silver-colored alloy. They are shank buttons. One of the four buttons has glue on the shank, and the hole is blocked. It might come off if you pick at it with something pointed. *It seems that this Madeira Topaz is a rare color among Swarovski's topaz colors. I bought these intending to use them for something, but I ended up just storing them. Size: 20mm I am decluttering and organizing my collection, so I am selling these. *Please note that there may be slight variations in size due to amateur measurements. Please purchase only if you understand that these are old items and have been stored at home. Vintage Swaro Rhinestone button Decorative button
