Earrings 925

These are very pretty earings. The stones i am unaware of what they are at this time but thsy are clear and the other appears to be black but when held up to thd light the black ones are more of a very deep dark blue. The clasps are stamped 925 as well as the inside of the back however they appear to be gold in color. I have polished them before as ive worm them several times & my ears get infected with metals that arent real gold or silver & ive never had that problem w/these. I dont believe the clear stones to be diamonds however they could be as they do NOT fog up when i breath hot air on them. Im not for sure but diamonds & Moissanite are thr only clear stones i know of that dont fog up & sometimes even Moissanite does. If these dont sale fairly quickly i will most likely end up taking them to my jeweler & asking them what they are but for now it is unknown. There is another marking on both the clasp & the inside of the back but my eyesight just isnt good enough to make out what is
