Polish artisans interpret this aquatic darling—the Blue Crab—in genuine Baltic amber and sterling silver, including pincers. This Baltic Amber Crab Necklace has an 18"l. sterling silver omega chain and pendant. Lobster clasp. 2.5" x 2" pendant. Prized since the Stone Age, treasured by ancient civilizations, and coveted by 18th- and 19th-century European monarchs, amber (particularly 40,000-50,000 year-old Baltic amber) is still highly valued for its natural translucence. A glowing organic gemstone (naturally occurring in various shades of brown, yellow, or green), amber is actually the fossilized resin of prehistoric trees. Natural inclusions such as plant life or insects increase its worth. FREE SHIPPING TO UNITED STATES. INTERNATIONAL CUSTOMERS CONTACT US FOR A SHIPPING QUOTE.
