These necklaces keep the crystal in it's natural beauty, 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. This piece is a tumbled quartz crystal netted in a wine cord - I like these because they are soft and round. This one is approx. 1.5" diameter (it's a bit of an oval shape) and netted in wine cord and sits approx. 30" (however you can tie a simple knot at the length you wish). These necklaces can be used for everyday wear however they are delicate and should be handled with care.
