King Tut Earrings Egyptian Diamond Cut Clip Luxor

Brilliant diamond cut  Tut clip earrings - findings from USA - each diamond cut was done by hand. Dark blue disc back of well not sure what kind of material it is - almost volcanic in nature - pourous material. 1 and 3/8 inches acorss. Clips are tight and secure. The findings come from my retired Luxor line - mint condition carefully stored. Nice set but the only set I can make.
