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.

colorado mt antero aqua 9.96 ct 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!

colorado mt antero aqua 12.58ct 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.

Colorado small aquamarines new gifColorado Aquarmarines.  Just arrived different bathches with the finest cutting done in Sri Lanka. Some 5x7mm Princess cut aquas as well as 4x6, 6x8 ovals, 4x6 ovals, 4 and 5 mm square Princess, rounds and pears (3.5 to 6 mm), and a few triangle cushions and pears. Way too many to list individually. Most are lighter colors, but quite a few surprisingly are eyeclean.

I plan to take some of these aquas and set into sterling pendants or earring sets (hopefully in time for the holiday season). In the meantime if you have an interest in these, let me know by email.

UPDATE: Many of these are now set into earrings and pendants which are now available for purchase. The individual sets and prices will be listed under my Colorado Jewelry page.

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 con,/TE,ditions 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.
