These are cute earrings.  They are big enough for an adult to wear.  Marked 925 on the post and backs.  the only problem that I see is that one of the stones is cracked inside on the upper part of the stone.  It might just be a flaw in the stone.  I am not worried about it, because I don't think anyone will get that close to see it.  It might bother some, however.  They are also made in the USA.
