Item Description

When it comes to gemstones from various US localities, some of the most well-known examples of gem quality Aquamarine are those from the famous Mt. Antero locality, but the nearby neighbor, Mt. White has been a source of gem material of equal quality, though in a much lower quantity. Fine gems from Mt. White are MUCH rarer than those from Antero, and I can honestly count the number of faceted Aquas that I've seen from Mt. White on both hands in my life. This stone is a beautiful custom faceted example with a "Modified Keystone" cut, and an enticing sky blue color. There are some very faint "tube"-like inclusions, giving the stone a gossamer-esque chatoyance, bordering on nearly a "cat's eye" gem. The gem was cut by Brett Kosnar of Kosnar Gem Co., who is a 4-time AGTA Spectrum Award winning gem cutter from Colorado. Fine quality, and a rare locality make this a very desirable stone, and it's also the birthstone for March, so it could make a great gift idea for anybody with a March birthday. Keep in mind that U.S. gems, are high in demand, and it doesn't matter if it's Benitoite from California, Rhodochrosite from the Sweet Home Mine, Hiddenite from North Carolina, Sapphires from Montana, etc., people are buying material from the United States at a higher rate than any point in history. Valued $1,244.25 high retail.
