Untreated 24.16 Carat Cushion-Cut Tanzanite Pendant


This extraordinary, untreated 24.16-carat tanzanite is truly an extraordinary gemstone. Encircled by 0.99 total carats of shimmering white diamonds, this brilliant cushion-cut gem exhibits the rich violetish-blue color for which these stones are known and so highly treasured. The clear, intense hue of this tanzanite is the most coveted of all these rare stones. In fact, deep blue tanzanites such as this one are worth more per carat than the more common light purple hues, as it is highly unusual to see this uniform color in such a large stone. Additionally, this stone's stunning setting in 18k yellow gold and platinum only enhances its incredible beauty. The gem has been certified by the American Gemological Laboratories (AGL) not to have undergone any clarity or thermal treatment, meaning the beauty of this incredible tanzanite is completely natural. Virtually all tanzanite stones are heat treated, so a perfect untreated stone such as this one is an absolutely extraordinary find. Download the AGL Certification The fascinating tanzanite gemstone only occurs in one specific location worldwide, the East African state of Tanzania, and remains one of the most sought-after stones on the market. Discovered in 1962 in the shadow of Mount Kilimanjaro, this new gem drew the attention of Tiffany & Co., which gave it the name “tanzanite,” and it has maintained a steady popularity ever since. To find an example of this incredible size, and of such enchanting color and quality is truly remarkable. 16" length
