This is a real gorgeous jewelry grade natural Gold Nugget from California. It weighs 14.3 Grains (0.93 Gram). From the rich gold fields of the Mother Lode Region of California, it measures 5/16" (8 mm) long. This California Gold Nugget has amazing texture and incredible color. It is becoming increasingly more difficult to find high quality natural gold nuggets from California as the supply is very limited since the gov't banned suction dredging in the rivers in 2009. It would look great in your collection of gold nuggets, and is a great investment as well. Comes with a certificate of authenticity.
