Vintage 925 sterling silver teardrop crystal earrings, Portuguese cut

One of a kind dangle earrings with large teardrop shaped faceted sparkly crystals. In excellent condition. I think this type of faceting is called Portuguese. It brings out a lot of sparkle and light movement. 3.5 cm long. There are faded stamps near the end of each hook. They are not really readable, but both earrings were professionally tested as 925 sterling silver.
