REAL - 6mm Black Pearl Necklace

Sustainably sourced off-round freshwater pearls, around 6mm in diameter. Very shiny, colors vary with light and you can see hues of blue, black, burgundy, brown and green. Hand knotted in silk cord, 18 inches long with a 2 inch extender. How to tell if a pearl is real: rub it against your teeth and it feels gritty.
