Circa 1950's, with 12K gold filled screw back findings and bales. The whale tooth ivory hoops are carved to taper thinner at the top and thicker at the base and dangle on a bale. Each earring has a genuine Alaskan gold nugget mounted on a pin that goes through to the back side of the ivory, and then are peened to secure. They have a 1-1/2" drop length, 1-1/8" diameter and weigh 6.2 grams. Excellent condition with only light signs of previous use. No cracks and display beautifully. So nice!
