Not as iridescent as it looks in the picture
It's still quite nice,  the backing has a very pretty pattern and the chain seems pretty sturdy.  I wish it didn't say the words "Fibonacci Series" on it (personal opinion,  I just think it looks tacky as it should be a "if you know,  then you know"  sort of deal.) But it's still very attractive. Weighs a tiny bit more than it looks.
