The focus of these necklaces are the crystals (or in this case fossils) - they are the star of the show, I have merely found a way to keep your stone with you at all times, letting the crystal support you and bring you joy with absolutely no damage to the crystal itself. Many people tuck my pieces into their bra to feel the crystal close to the body. Each piece is one of a kind (in nature there are never two crystals exactly alike) - so the piece is as you see in the photos. I had these in my shop (un-netted) and they sold right away so I never had time to net them - there's a bit of a crazy attraction to them. Ammonite are ancient fossils from the cretaceous period. They are a very powerful earth healing fossil. It's spiral shape symbolizes continual change and evolution. Ammonites have absorbed cosmic energy over eons of time and help to stimulate the Chi within. An Ammonite can be use to attract health, prosperity and success. Think of the Ammonite as a filter, drawing in dense tired energies and moving them through the spiral to release fresh, positive, loving force energies. Physically, Ammonites can help to increase stamina and vitality and can help lift depression. I have two at the moment, one is slightly larger and it measures approx 1.5" in diameter and the necklace is netted in brown cord and hangs at approx. 30". These necklaces can be used for everyday wear however this is actually a fossil and doesn't have the same density of crystals, so I would be particularly carful with this piece, it would be a nice piece to hang next to your bed. They are delicate and should be handled with care.
