Vintage cufflinks featuring a beautiful blue Azurite gemstone set in 930 silver. The square shape adds a classic touch to any outfit and the unisex design makes them a versatile accessory. These cufflinks are perfect for those who appreciate fine jewelry and are looking for a unique addition to their collection.

I did lots of research, and the best I can figure out is there's where it's created in the Netherlands, or perhaps germany.

I have no concrete prof of that. I have not Been able to find any other cufflinks like them.
