I sincerely doubt that the chain will last very long.  It reminds me of another necklace that I purchased from Amazon a while back....the chain broke twice.

The actual jewels are beautiful, nice and bright and beautiful, but when you hold the necklace up - or in today's case, wear it, the chain is obviously too FINE for the size of the jewel.  This necklace needs a larger chain - the proportions aren't right.

It's very pretty, though and until it breaks, I will wear it.  I'm just not planning on it lasting too long.  I think someone goofed when the put the jewel with the chain.
