DALLAS — A massive sample of crystallized gold from Eagle’s Nest Mine in the Michigan Bluff District in Placer County, California, dazzled brightly at Heritage Auctions’ Nature & Science auction July 20, drawing multiple bids before selling for $187,500, with buyer’s premium, to claim top-lot honors. Weighing 9.9 troy ounces and measuring nearly 6 inches in length, this extraordinary specimen topped the results of 16 gold specimens sold in the auction. In addition to its sheer size and exceptional color, what makes it so appealing to collectors is the expansive crystalized surface area. For more information, www.ha.com or 877-437-4824.
