Very unique, folk art Moroccan style Christmas tree topper. I can't be sure of the underlying material (glass? gourd?) because the thing is absolutely covered in tiny glass beadwork and glitter accents. The glitter does NOT shed or come off when rubbed. It appears true vintage, I'm guessing at least 1960s if not older. Hand-painted with a gold paint at the base. 

Stands 11 inches tall with a base opening of 1.5 inches and a max width at the larger bulb of 4.5 inches.
