This is a lot of nice small cleanish stones. They are all 3/4 ct or less, attractive. 6 emerald cuts, 3 or 4 small rounds, 7 ovals, and a teardrop and trilliant available.
Price depends mostly on depth of color, around $50-$100/ct.


Ovals and others

Emerald cuts and rectangles.
Aquamarine, 2.99 ct elongated scissor cut, 4.6x17.7mm, 4.8 mm deep. Pale blue, SI to VSI.
This is the last gem we collected off the "Slide" area of Carbonate Ridge (Mt. Antero), years ago. The majority of the gems from that spot were on the pale side, but could be fairly good sized. This one is cut fairly deep, so you will need a deep mounting for it. Would make a nice pendant.
$150.00 (Stock# AQBS-0299)
Aquamarine, 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!

comingsoon Aquamarine from Mt. Antero. 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.) & the  highest known gem producing area in the USA. Virtually all gems and crystals occur above 11,500 ft.
Currently working on a new batch from rough I was fortunate to obtain from the Cardwell's mining venture, shown on the TV show "The Prospectors." I hope to post anything that comes available as soon as possible. The gems below will be from that batch.
Aquamarine, 4.15 ct Portuguese style cushion. 7.8x13.6 mm.
Has the typical Mt. Antero inclusions, but is top color, even better than the picture shows. This is the best dark color you can get except for a few special collector pieces. I was able to buy some pieces off of the Cardwell's claims on top of the knob/snowpatch area that they mined this summer and a few previous ones. These stones are fresh off the dop. This one would make an especially nice ring or pendant, and is the best color of any larger rough stone I was able to purchase. They probably won't last long.

Aquamarine, 3.63 ct emerald cut, light blue, but a little darker than the picture shows, 8x12 mm. really fairly close to eye-clean for an Antero gem. Would make a great ring or pendant gem, shallow enough for a larger ring. $399.00 (Stock #AQBE-0363)
Aquamarine, 7.69 ct Portuguese cushion cut, light blue.
A large stone that would make a nice ring or pendant.10.1 x 16.0 mm. Has the typical flaws/inclusions of Mt. Antero material, but still faces up well. One flaw about 1/4 way up one longer side could be covered with a designer prong no doubt. Has more brilliance than the picture shows, I will keep trying to get a better picture.

Aquamarine, 2.43 ct emerald cut, medium dark blue.

$607.50 (Stock #AQBE-0243).
Aquamarine, 2.90 ct keystone (or kite) cut.
Decently cleanish, has a few inclusions toward the base. Lighter blue color tone. A very unusual gemstone, if you like something different in shape, 8.3 x 18.9 mm.
$290.00 (Stock # AQBK-0290)
Aquamarine, 3.81 ct oval, Portuguese style, 8.7x 11.7 mm.

Fairly close to eye-clean and faces up really well. Light blue.
$409.50. (#AQBP-0234)
Aquamarine, 3.35 ct, scissor cut.

Please note: Much effort has been made in the attempt to get as accurate a picture as possible of our gemstones. Please 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 the availability of a gemstone, simply drop us an email or call us. For information on our acceptable payment methods, guarantee, shipping costs, and shipment preference see our Terms and Conditions page.
