Prehistoric woolly mammoth ivory is a beautiful and naturally-preserved remnant from the last ice age. While mammoths roamed most of North America, their tusks are being unearthed today in Alaska, the Yukon, and Siberia, where they were preserved in the permafrost for up to 200,000 years.  This genuine prehistoric woolly mammoth whale tail pendant is a special way to remember Alaska. Comes with sterling silver chain.  Genuine prehistoric woolly mammoth jewelry is already very old and can last a lifetime with proper care. Avoid extremely hot or cold temperatures. To clean your ivory jewelry, apply a small amount of mineral oil and buff dry immediately with a soft white cloth. Designed by Ivory Jacks.  Whale tail with side hole measures 1.5" wide. Includes silver chain, approximately 18 inches long.
