Cute earrings with 10K WG blue topaz! ^^ They have backings. I think the white stones were also white topaz, but my memory is hazy(´・ω・｀) I forgot if they were diamonds or topaz! But they are definitely natural stones. I haven't used them much, so I think they're beautiful (*^^*) As a bonus, I'll include 18K gold silicone backings! Dangling earrings Marking: K10WG Topaz I will ship via Nekopos with simple packaging!
