This Fairy Stone weighs 28 grams and is 1.50 inch in diameter. It is rare and unique...perfect for any rock collection. Ready to enjoy, wrap or make into jewelry, or inspire something of your own inspiration creation. Fairy Stones are made of bacterial residue which grew around organic remains. The matter that could not be absorbed was released into gelatinous form, deposited on the lake bottom in concentric shapes. Contact with limestone from the water hardened it into stones. This piece has horsetail plant filaments, embedded and fossilized with the conglomeration. The name “Fairy Stones” was given by the Algonquin people who could not believe it was natural.
