I have cut a variety of rare and collector gemstones over the past 40 years for mine owners, gemstone dealers, and individual collectors. You will find some of my gemstones in a museum, on the table of gemstone dealers at a gemshow, and in the "safe" of collectors. This page highlights the collector and rare gemstones I currently have in stock. If you are interested in "collector gemstones," you will want to check back often as I am constantly cutting and adding to this page.

amethyst5239 Amethyst, light/medium purple, Portuguese pear shape, 21x30x17 deep mm, 52.39 cts, SI to VSI, Halleleujah Junction,Nevada.
Has one light veil that doesn't distract or affect brilliance. Your chance to own a very rare American amethyst from Halleleujah Junction, Nevada, a collector's item for sure. This locale has produced some of the largest gem amethysts in No. America. They tend to be on the lighter side, but beautiful pinks. This is probably the best color of any pieces I have left, and is a good strong medium. Would make a gorgeous pendant, or keep as is as a collector's piece to treasure forever. There are just not many of these around.

Would make a nice pendant or just to put away in your collection. Priced at only $20 per carat, but will consider offers.

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. Note: I am frequently "off the grid" when I am in the field collecting and might not be able to respond to your inquiry promptly. I will respond when I am once again in cell phone range.
