Hand-blown Mercury Glass Kugel Christmas ornament in shape of berry/grape cluster.  Highly collectible.  Circa 1800-1900's.  Ornament has some weight to it, has a brass cap and is approx. 3" in length. It is a beautiful red color however when held in the light, the mercury glass on the interior sends off hues of red, orange and gold.  Aged patina as would be expected.  Truly stunning.

I will be listing quite a few of these as I was lucky enough to find them at an estate sale :)
