Hello dear friends!!! Maybe you know something about my find!!! Is it interesting or just a fashion jewelry Size 1x1 in.!!! Thanks for your answers!!! Mummytrol!!!
It has a great look to it, but as Kray and Bob have already mentioned it's likely costume jewelry.
The nice part is, with Christmas coming all you need is a new silver chain and you have a re-purposed gift.
Yours does look like silver. Can't make out the 925 stamp on yours, but the pin shown below has a faint stamp that suggests the stamp may be done somewhat haphazardly.
The Maltese Cross design (Iron Cross) coupled with a black onyx stone is a common motif.
"Nice set of sterling silver and onyx pierced earrings. Stamped 925 on each piece. The disc measure 1 inch long and wide excluding the sterling fish hooks. They weigh a total weight of 7.3 grams."
