This awesome natural jewelry grade Gold Nugget from California weighs in at 12.7 Grains (0.83 Gram). It is a hand selected raw gold specimen of the very highest quality and it has gorgeous color and a very pleasing shape and texture. From a river in the historic gold fields of California, this beautiful gold specimen is 3/8" (9 mm) long. This is a super nice California Gold Nugget. It is very hard to find high quality California gold nuggets for sale, as the gov't banned suction dredging in California in 2009, which is how most placer gold nuggets are found. It comes with a certificate of authenticity.
