I believe they are factory made. I won them in a mystery box I bid on. they are still sealed in plastic as shown.on the back on the plastic that the earrings are in there is a made in china tag. That is all the info I have, hope in helps.
thank you I like these and the yellow and green ones I have posted, but I cannot wear earrings unless pure 24 k gold so its my loss and a gain for someone else. Plus I throw in with gin, a bracelet or maybe another set of earrings or something. I try to keep people happy :)
