I bought this little choker mainly for layering with another opal necklace.  However, that isn't really working for me--my other necklace is a natural opal on a solid 14k gold chain....and this one, although cute, doesn't really compare.

But it's OK by itself, and I don't regret the purchase.  At least I won't regret it unless the finish wears off the chain.  The opal is a little bland, considering that it's created.  The picture I've attached shows the choker at its smallest length.  It does have extra length that you can use to adjust the fit if your neck is a bit larger, or even if you're just looking for a necklace that hangs a bit longer.
