Colorado Mt. Antero Aquamarine Gemstones for Sale

Mt. Antero aquamarine rough is rare and difficult for us to obtain on any consistent basis. Mt. Antero is the 10th highest peak in Colorado (14, 269 ft.) and the highest known gem producing area in the USA. Virtually all gems and crystals occur above 11,500 ft. Aquamarine is considered the March birthstone. Mt. Antero aquamarines are very popular with Colorado residents and visitors, especially if they have visited the site personally.

Stones from Mt. Antero typically have small flaws and seldom reach over 10 carats. Crystals are usually not large and tend to be lighter in color, or at least the cleaner crystals and areas do. Good facet grade in darker colors is quite rare. The largest clean gem I've ever seen from here is 23 carats and light in color.

coaqua0706 soldAquamarine, 7.06 ct pulsar cut.
Very rare over 5 carats in good color and relatively clean, this gem is medium-dark blue. One of the best Antero aquamarines we've ever had in 40 years of business and collecting! It measures 9.7 x 12.4 mm, and American cut into a fancy pulsar cut. The pulsar cut maintains the emerald cut outline while giving much more flash. Fits in most standard emerald cut heads. If you want a one-of-a-kind piece from Mt. Antero, this one is it!

coaqua1258 soldAquamarine, 12.58 ct, scissor cut, 8.3 x 24.7 mm., light medium to medium color.
The largest fine quality stone from Antero that I've ever offered. Rough was found a few years ago by John Melby, who used to prospect with Andy Taylor, both mentioned in Jacobson's Antero book. Both were fine gem cutters, but are both recently deceased. I purchased the rough from his estate.
Not flawless by any means, but quite clean for the size. Stones of this size from Antero are very rare.
This one is a special piece.

coaqua0769 Aquamarine, 7.69 ct Portuguese cushion cut, light blue, 8.6x13.7 mm.
Old Snowpatch material. A large stone that would make a nice ring or pendant. These larger gems from Antero are hard to find. Has a few typical flaws/inclusions of Mt. Antero material, but still faces up well. One visible whitish flaw about 1/4 way up one longer side could be covered with a designer prong or bezel no doubt. Priced accordingly.

PLEASE NOTE: Much effort has been made in the attempt to get as accurate a picture as possible of our gemstones. Keep the following in mind while shopping: Cameras do not see color exactly the same as the human eye and lighting conditions often cause large variances. When taking pictures for the web, we have found that it is very difficult to capture the brilliance that the human eye sees and photos cannot often show all of the stones' ambiance and jewelry pieces fine detail. Also computer monitors vary and often color tones are set to suit the viewer's preferences. When shopping, remember that "the pictures are meant as a rough guide only." All our products have a money-back guarantee (see terms above) so there is no risk in ordering from the Buena Vista Gem Works.

To order or check on the availability of the piece(s), simply drop me an email or send me a text at the email/phone number below. Please include the Product Name and Stock Number when inquiring about product or placing an order. For more information on ordering, my guarantee, payment methods, shipping preferences, and shipping costs, see my Terms and Conditions page.
