Made by BSK probably in the 1970s or 1980s. They are gold tone or plated and remind me of swirling eddies or the eye of a tornado. The earrings are made to look like lots of little connected sticks that radiate outward.
The sparkle comes from the different finishing of the sticks. Some are mirror finish and others are textured. Some flat and some ridged or gouged. Real showy.
The earrings are marked BSK, have sturdy clip backs and are just over 1 inch in diameter.
Condition is very good, not quite mint.
