A glittering mid-nineteenth-century nature-inspired brooch, rendered as a stylized oak branch with an acorn on top, is artfully handcrafted in rich 18 karat yellow gold set with numerous early cushion-cut and table-cut diamonds, together weighing 1.10 carats. A consummate early Victorian era jewel, most likely of European origin, measuring a sizable 2 1/2 inches by 1 1/2 inches.
