|Get your name on the list Affordability and distinctive beauty have earned this gem a status that rivals sapphires.�Douglas Hucker, Executive Director; American Gem Trade Association In the past 100+ years, there has been precisely one change made to the list of official birthstones. The hallowed list, finalized in 1912, was believed to be unchangeable, because the world’s finest gemstones had all been discovered. Except they hadn’t. In the late-20th century, a lightning storm in Tanzania set the foothills of Mount Kilimanjaro on fire, revealing an incredible violet-blue stone beneath the surface, known as tanzanite. In 2002, the American Gem Trade Association agreed to review the list and immediately added tanzanite as the official birthstone of December. The Undeniable Tanzanite Necklace gives you 160-total carats of list-altering tanzanite, direct from the foothills of Mount Kilimanjaro. That’s 160-total carat weight of violet-blue vivaciousness, the stone that the masters of gemstones couldn’t say no to, all in one necklace. Because it is found in only one place, tanzanite is calculated to be 1,000 times rarer than diamonds and some estimates say the entire supply will be exhausted within 30 years. Now’s the time to bring some violet-blue beauty into your life, before the price on these rare beauties starts to climb as steeply as the mountain it came from.
