Each Agate crystal is unique, therefore the crystal necklaces you see below are one of a kind, and I have only one available of each. The shopping cart will allow you to add more than one, however, if you do add more than one to your shopping cart, when you check out, it will reject the order (by saying "item sold out"). So please just add one to your cart. What you see below will be the actual crystal necklace you buy and receive. Please note that color may vary slightly to what you see on your computer screen due to computer light variances. Mahalo!
