Here is a lovely pair of modernist Sterling silver ear studs enhanced with one large and three smaller stones.  I do not know whether these are crystal or CZs. The studs were purchased in Denmark.

Here are a couple of pairs of Sterling silver ear studs by the contemporary Danish silversmithy Støvring Design, based in Randers since 2007.  The design of no.1 is a four-leafed clover, and that of no.2 is a swirling droplet.  Both purchased as New old stock.  For sale indivdually or together at a discount.
