Accompanied by AGL report #CS 63850, dated October 21, 2014, stating the emerald as: natural, USA (North Carolina) origin, with minor traditional clarity enhancement, with special comment « The unusual combination of size, provenance and quality factors represented in this material contributes favorably to its rarity and desirability »
Note: A larger faceted emerald of 64 carats known as the « Carolina Emperor » was cut in 2010. However, the present stone, « The Carolina Queen » still remains the largest, gem-quality emerald found in America.
This historical emerald of exceptional quality, size and provenance was found in Hiddenite, North Carolina in the fall of 1998. It is the largest faceted emerald ever found in North America and the finest and largest ever recorded.
Located in the rolling foothills of the Appalachians, the small town of Hiddenite has long been associated with a wide range of gemstones, including emerald, ruby, sapphire and the rare gem hiddenite, the type locality for that stone (the deep-green sister of the lilac-pink gem known as kunzite, named after George Frederick Kunz, gemologist and former curator of the American Museum of Natural History Mineral Collection). In the late 19th century, Thomas Edison, the inventor, asked Kunz and Professor William Hidden to visit the area to seek platinum for his light bulb filaments. The men did not find platinum, but Prof. Hidden discovered the gem that was then named after him (as was the town). Hidden and Kunz found 63 different gems and minerals in an area along a fault line in what they described as « the most complex geological zone in the world. » Decades passed with few finds of any significance until, in the early 1970s, Tiffany and Co. purchased a 13-carat gem, known as « The Carolina Emerald » amid much fanfare and publicity. At the time it was believed to be the most valuable North American gem until the present stone was found in the late 90s.
It was not until the 1990s that miner James K. Hill discovered a vein yielding large, gem-quality emeralds including a 70+ carats crystal from which the present stone and another smaller one were cut. The smaller oval stone, weighing approximately 7.85 carats, was dubbed « The Carolina Prince ». It was stated to have sold privately in 1999 for a record total of US$500,000 or over $63,000 per carat. The second stone, which is the present offering, was cut from that same rough, yet is of significantly greater size at 18.87 carats, and is known as « The Carolina Queen ». Notable not only for its large size, the vivid color sets this stone apart from any others. The color in North Carolina emeralds results from the presence of chromium, the same coloring agent in the famed emeralds of Colombia. The color of the present emerald is comparable to very fine Colombian stones.
It is clear that no other American emerald rivals this one either for color, quality or size or historical provenance.
