I have to say that I've had this necklace on my wishlist for years.  I remember it being quite pricey when I first saw it (around $100 maybe?) so when I saw it was on sale for $40, I purchased it right away.  I see a lot of people were disappointed in the necklace, but I really like it.  It looks pretty much like it does in the picture, except the heart is a slightly darker shade of red and it is flattish.  It's not a round puffy heart, the back is flat and the front is slightly rounded.  You can see through it, just like the picture.  It looks like it's made really well, and will last a long time.

I don't think it's worth $300 or even $100 but $40 seems like a very reasonable price for this necklace.  I have the purple one on my wishlist too.  I plan on getting it soon!
