Why choose us?

NGC's Gems (2%)
Fine Jewelry Store Gems (18%)
Shopping Network Gems (80%)

 

What makes National Gemstone different from most jewelers and gem dealers is that we specialize in the top 2% of the world's gem production. Although that makes our job considerably more difficult when buying, it also makes it much more interesting! In order to put this in perspective, please view the pie charts above. Approximately 80% of all gems are low quality and usually sold on shopping networks and in retail jewelry store chains. Another 18% are found in fine jewelry stores. Only National Gemstone, a few gem dealers and a handful of jewelers search for and sell the top 2%. How do we prove this? We submit our gems to the world's foremost gemstone grading laboratories (American Gemological Laboratories and Gemological Institute of America) for independent verification of quality. If you want to collect world class gemstones or procure the highest quality gemstones for your jewelry, feel free to call National Gemstone at 1-800-458-6453 or email NGC, Attn: R. Genis

Payment, Delivery and Taxes

National Gemstone accepts cashiers' checks, money orders, money fund checks, personal checks, and bank wires in payment for gemstones.

We do not accept credit card, Paypal or fax orders.

All gemstones purchased from NGC will be sent to you, at our expense, via insured UPS or Federal Express. Conversely, please return gems via the same method. If you live in a large city, we can arrange Brink's deliveries for important gems. Contact National Gemstone for a quote on the extra fees involved with Brink's.

If you purchase your gems from outside Arizona, no Arizona sales tax is assessed. However, if you are an Arizona resident, you must pay Arizona sales tax.

 

Guarantee

If, for any reason, you are not 100% satisfied with your gem purchase upon receipt, National Gemstone will allow seven days, from the day you receive the gem, in which you may contact National Gemstone offices for a complete refund. As a general rule, if we UPS overnight to you, you should return the stone and grading report in the same manner. You pay for the return shipping back to National Gemstone. Upon receipt of the gem and grading report being returned to National Gemstone, we will return the funds in the exact manner. If you wired funds to National Gemstone, we will immediately wire back to you. If you sent a personal check, we will immediately return a company check. In the 30 years we have been in business, we have never had one complaint lodged against the company. We take our reputation seriously.

"National Gemstone. A sparkling page. Literally. While investing in gems is probably not advisable for the average investor, if you'd like to learn something about valuable gems and enjoy looking at pretty pictures on the net this is worth investing some time! Some very useful information about gems and investing in gems for fun and profit is available here, but more to my liking are the spectacular gifs of stones in the Smithsonian Gem and Mineral Collection."

"www.preciousgemstones.com A great site run by gemstone guru Robert Genis, president of National Gemstone (NG). Good information on grading and collecting, links to digital images from the Smithsonian's collection of stones, and an archive of the Gemstone Forecaster Newsletter, which Genis publishes."

"Robert Genis is president of National Gemstone and is an industry veteran of 30 years. The depth and breadth of his involvement in the industry shows in his website with its 13 sections. The most obvious barometer of Genis' trade knowledge is in the quarterly produced The Gemstone Forecaster, a general news and market report produced in hard copy and HTML versions. National Gemstone has a no frills website that is crammed with useful information no matter where you are in the gem trading or gemological pecking order."

"This page could serve as a useful introduction for those getting their feet wet in the world of fine diamonds, precious stones, and collector gemstones. You'll get a wealth of education about diamonds and gems from the President of National Gemstone, Robert Genis, whose 25 years of experience in the field is quite obvious. Aside from the four Cs, learn how to read a GIA certificate and why some jewelry stores charge 100-160% over wholesale price for diamonds. His quarterly newsletter, The Gemstone Forecaster, goes into great detail reporting on the different gemstones (diamond, emerald, ruby, and more) and why their prices are either up or down. To get a taste for these rocks, view photos of great gems from the Smithsonian Institute collection."

"Opal, alexandrite, tourmaline, sapphire, and almost every other gemstone on earth has an entry at the National Gemstone Web Page. A brochure lists prices, helps collectors understand grading reports, and shares tips on how to recognize rare and precious stones. Amateurs should read the How To Collect Gems for Fun and Profit. We would like to see more photos of the stones themselves, but the link to the fabulous riches housed at the Smithsonian makes up for a lot."
