Anyone know where I can find a pair of earrings like these?

[makemepretty]

I had this pair of earrings that I had to part with and I miss them like crazy. I bought them second hand so I have no idea where they originally came from and I can't find any similar. This is the information I have about them: These measure approximately 5/16" in diameter. These have 3 grams of 18K gold. The posts and backs are marked: 750 3108AL. They are 18k blue glass diamond center studs.
