Upon glancing "Swarovski AB Crystal Heart stone on fine chain" and the price, I was over the moon. However, I should've known (but my naivety got the best of me) that the price was too good to be true for a proper Swarovski crystal. I only realised this when the product reached me - I was so disappointed. The chain is not fine and the crystal was crystal glass. But the seller does mention that the crystal heart is a 'Swarovski Crystal Component' so it is really my fault for hastily purchasing this item. However, in saying that, the pictures of the necklace really do make it look much better than it is in real life.
