SINGLE Open Gallery Clear Stone Stud Earring

This SINGLE stud earring is made of a gold tone metal and has a simple post finding. The head of the earring features a single clear faceted stone with an open gallery below, allowing plenty of light to shine through it. I can confirm that the stone isn't diamond but based on the colourful refraction and absolute sparkliness, I suspect it might be CZ rather than just glass. The stone is held securely by 4 prongs. I wasn't able to see any stamps or marks on the stud, including what you see in pic 6, which is not a stamp. The stud has normal wear, but the issue affecting wearability would be that it is alone without a mate. Stone dimensions: 8x8mm Weight: 0.96g Love the piece but not the price? Make an offer!
