This is a truly unique and beautiful necklace. Inside the tiny bottle pendant is real moss, sand, and a tiny pyrite rock that was found in the mountains of Colorado, making a cute miniature nature scene. Pyrite is also known as fool's gold and looks like gold. It is a really cool rock! The necklace hangs on a very soft, tan leather cord that is 16'' but is adjustable to go more. It's a perfect way to carry a stylish piece of nature around with you, especially if you live in a city. Better yet, you don't have to take care of the moss at all. This sturdy, beautiful necklace is sure to attract complements and is perfect for a gift or yourself. If your looking for something for mother's day, this is the perfect gift!
