Denver Gem Show 2017 Review

31th October 2017 by Mike Petrov

A little bit late, but here is a review with some pictures from the Denver gem and mineral show, September 2017

Well, its fair to say that its been the busiest summer and fall, that we, The Russian Stone team, has ever had. Within three months, we had the Bancroft gem and mineral show, we visited the world famous Pyrite mines in Navajun Spain, went to Denver for the big gem and mineral show, as well as visited Munich gem and mineral show in Germany. This is a quick review of the Denver gem show, which, some will argue is the second larest gem and mineral show in the Americas after Tucson.

Entrance to the Denver main show

Here is Elena saying hello to the friendly T-Rex at the main show

Some delicious looking Malachite with Chrysocola polished pieces straight from DRC - Congo, historically known as Zaire.

Garnet, Granite...whats the difference

Garnet, Granite...whats the difference, its all $50/kg. Here are some unusual black Melanite garnets from Mali.

100kg of Tanzanite anyone?

Lowest quality Tanzanite, only $150/kg, note the buckets to the left of the table. Each one with 100kg of Tanzanite. So doing the math, you can get yourself a tonne of Tanzanite for only $150,000. Maybe they offer discounts on per-tonne bases ... ha ha

Turquoies anyone?

Some beautiful Turquoise, look at these colors. Not sure if there is a yummier color in the gem world!


Ok maybe there is a yummier color...Tourmaline. Known as a chemical dogs breakfast in the gem world, the gem with a very complex chemical composition, which is the reason for the huge array of colors. Here are some beautiful pinks, reds, greens and some blues from Brazil.

Quartz clusters

The selection of Quartz is never dissapointing from the Brazilian dealers. One of many tables at the show. Clusters, Lemurians, Spheres, Pyramids, Merkabas, Voguls, Tumbles, anything you are after, they will make it for you.

Huge selection of Amethyst Geode spheres

Although these have been around for a few years, noone has ever brought such an extensive selection of these as Luiz here. Beautiful deep colors and great shapes, we have a big selection of these available at our gallery. Took couple hours to sort through all of them to pick out the prettiest ones.


Another delicious gemstone - Tanzanite!! Beautiful intense colors.

Elena with Grape Agate jewelery

Elena looking through newly made Jewelry from Indonesia, behind some massive newly found (in 2015) Grape Agates from Indonesia as well

Silver specimens

Wonderful collection of Silver specimens from all over the world. You can see the reflection of Valeri taking the picture.

Mortal Combat

Taking bets now for next years rematch between Valeri the vicious geologist vs. T-Rex the monster with tiny hands

Rose Quartz

Stone pictures

Mike and Elena beside beautiful pictures made from Zoomed in microscope pictures of various gemstones

Diamond jewelry

Pretty interesting new method of cutting Diamonds along the crystal, kind of like bread, into pieces thinner than hair. Each of those pieces is a fraction of a carat but looks massive - quite genius if you ask me.

Amber bracelets $3 each - yeah right

Looks like Amber, feels like Amber...but something is not right, does the price give it away? As always the show is filled with fakes and counterfeits.


Incredible Tanzanite cut stones and crystals at the Arkenstone display

Some specimens to drool over

Of course when visiting the Mariott, you can leave your wallet at home and come and drool over specimens like these, stones that museums cant even afford

Face of the show

How is this even possible

Chrysocola growing out of a Malachite matrix. How is Mother Earth so creative??

More stunners

More stunning specimens. You can imagine why the price tag on each one says "P.O.R" - price on request

Surprise on the way home

On the 2500km drive home, we got this surpirse attack from the sky in Nebraska. Golf-ball sized Hail like getting show at by a machine gun over the metal roof of the cargo van. I've never seen ones this size, to our luck the windshield did not get damaged.

See you next year Denver

Thank you Denver, see you next year!!
