I must say I was really surprised when I looked underneath the little bag with the crystals and found a little folded up note, Cut in the shape of a heart, with a handwritten message from the seller. What a nice, personal touch! The quality of the crystals is amazing. I do understand that 3 of them are synthetic materials, but the rest are genuine crystals. They are set very well, and look like they will hold up well. The colors are wonderful! Ive seen crystals like these for sale at malls for much more... at least $20 for just one, so this is a great price. They came with two different chains - one silver, and the other, a black thin rope. Its very easy to switch the crystals out on each of the chains. You can wear two crystals together, on each chain, if you like. I am more than happy with this purchase, and highly recommend this seller and items. I did not receive this item for free in exchange for a review. All of this is based on my honest opinion of the item.
