These are pretty, do they look like costume jewelry.... yes....but I like costume jewelry and I love 1928 jewelry.  They are a little bigger than what I usually wear ( these are like the size of a quarter) but I still like them, not too heavy, but you still know your wearing a pair of earrings.  My earrings are darker than the picture, almost a very dark blue/green, but still very pretty and the backs of the earring are also very decorative and nice.  Are they worth the 30 something you might end up paying.....I'm still on the edge with that, I think they would of been a better value if they were 18 to 25 dollars.
