sterling silver 925 purple marcasite teardrop ring

i am unsure if this ring is amethyst or purple glass. it said amethyst when i bought it but i don’t know if thats true so i thought it was worth mentioning! there is patina on this item so please be aware before purchasing. i leave it up to the buyer to decide how they want it to look. i was so excited to receive it but the size was too big, i thought it was a size 7 but i believe its a size 8 or so. it’s been sitting on my vanity for a while. id say size 7.75-8. it’s super pretty though, its a pale purple. it might not be everyone’s cup of tea but i thought it was an interesting design. it is stamped 925, i have inserted a photo of the stamp as well! this was pre-owned before me. please dm me with any questions or if you want more photos. thank you!! i am open to offers i include free gifts in my orders! :3
