This is such a beautiful, dainty piece! The tiny pops of color really set this apart and I find myself wanting to wear it every day! One thing to note when choosing your length... At the shorter length (I chose 15 inches) the Peruvian blue opals are higher up around the neck, so my long hair hides them somewhat. If you really want to see them, a longer length would show them better.
Also, if you like coordinating pieces like I do, I highly recommend the "Pretty Little Things" earrings and the "Wrap Around" ring... WITH the matching Peruvian opal and Mexican Orange Fire opal stones, of course! You HAVE to check them out!
