Denver Mineral Shows 2017

Last Updated: 17th Sep 2017

By Jolyon & Katya Ralph

This is a LIVE report, keep this page loaded for live updates - new images will appear as they are added.

And so it begins again! Welcome to the Denver Shows 2017.

We now have a team, a real actual team, doing live reports in Denver between now and the 17th. So keep watching this report to see the latest updates from Jolyon, from Erin, from Nathan and maybe more.

This year we're getting excited about the Mindat.org fundraising auction being held on next Saturday evening at The Original Denver Gem & Mineral Show - see http://www.denvermineralshow.com - and we're going to be asking you all here to donate something for us to sell to raise funds for mindat.

We're in Colorado, so we'd better start off with some of Colorado's best: the Arkenstone has a suite of exceptional Sweet Home Mine rhodochrosites. - Erin

We'll be seeing many of you around Denver, but here's a reminder so you know our faces!

Tabitha Brown and Paul Stephen Cyr of Deep Seeded Trading Post have generously offered to be home base for mindat t-shirts until the mindat.org booth is open at Denver Mart. Stop by the National Western Complex booths 12-15J (third floor) to grab your shirts now!

A few things before the day is over - Samora has a lovely Hopkington, Rhode Island amethyst. - Erin

Throwin Stones has a number of Argentinian rhodochrosites available.

Southern African Minerals has many excellent Goboboseb amethysts - I particularly like the zoning in this one.

Geotrope Minerals has a few things that look familiar - Kola!

The days are always over too quickly - a few creatures are still lingering about, but most folks have gone home. We'll resume in the morning!

Show time again! I'm back at the Western National show for a while.
The Earth Scientist (formerly known as Willie Hawes) has some fun pieces of hyalite/chalcedony from San Luis Potosí, Mexico.

While there are plenty of fantastic things to look at out on the main floors (and parking lots) of the shows, those who have ever worked the shows know how much of the work actually goes on behind the scenes. I'm back in my "office" working on one of our secret projects - but stay tuned, it won't be a secret for very much longer! - Erin

Meanwhile Jasper James at Fallin Crystals is completing his give away contest. Someone has just won (it was not me)!

I'm over at Miner's Co-op today - Mel's has a selection of minerals and localities that haven't been seen in decades. Here's a nice Jomac Mine oswaldpeetersite, sklodowskite, and pink smithsonite collected by Pat Haynes of The Virgin Mining Company October 10, 1999.

By Design Gems has a selection of exceptional cut gems by Jim Barzee and Matthew Flynn.

Malcolm Alter Minerals has a selection of a little bit of everything, including some Daybreak Mine autunites.

JaM's Rocks has a selection of large Amelia Mine, Boleo District boleites on matrix.

We're having a good debate over whether Arizona or New Mexico irridescent garnets are better over at Rock Out Gem, Mineral, & Art Exchange.

Rock West has some Lily Mine specimens and would love some confirmation on the differences between atacamite and clinoatacamite - I don't know the answer but if anyone wanted to stop by and help, it would be much appreciated! -Erin

Scully's Minerals has some specimens from one of my personal favorite collecting spots: Nacimiento Mine azurite concretions.

Jolyon here - finally in Denver to join the rest of the team and I'm starting today at the National Western Complex

That the elevator up one floor to the mineral show.

Will it be possible to bid in the auction online, so those of us not in Denver for the show can also participate (and maybe make the prices realized better for Mindat)?

What usually happens is that some items are kept back for an online auction. But I think online bids in the live auction may be too complicated to run. I won't rule it out entirely though.

$300 for a Uralite from Calumet Mine?!
And then there is Justin...yep! Can't wait to see everybody at the Midat BBQ.

Just curious, wouldn't Bou Azerbaijan, Morocco's hematite ball be goethite? Being from Colorado we have similar specimens in appearance but they are goethite...? Looking at the location for Bou Azerbaijan, Morocco in MinDat, I don't see any hematite specimens resembling that but I do see goethite (none look the same either). But the resemblance to Lake George goethite is quite similar...

Scott Rider

I have to agree. $300 for a Calumet Mine uralite?! I remember a rockshop in Colorado had dozens of these specimens for around $6-$8 a piece. This hobby has truly gone off the deep end.

Re: "Fantastic things at Unique Minerals". The asking prices for those labels visible in the shot total $318,500! Lovely specimens for sure, but it makes that $300 uralite look like a bargain! I was planning on attending Denver this year for the first time, but couldn't make it. If all specimens are out of reach to the average collector, then it makes little sense for me (as a retiree) to attend these shows. If you have a chance- post some photos of what is available at the show for the more "bargain minded" collector like me. Great coverage btw on this and other shows. Thanks Jolyon and your team, I always enjoy these live updates.

The Denver shows have specimens for all interests and budgets. The Fine Mineral Show features pieces geared more for high-end budgets, but the other shows have specimens for novice through competition level collectors. It definitely pays to comparison shop, but if you see something that you really like you should get it then (because it may not be there if you return later).

Kevin Conroy

Thanks all for the continuing coverage of the show. Some these specimens are mind blowing, especially that emerald from the Kagem Mine!

I love Jim & Gail's Silver display ... stunning

Hi Jolyon

The Chinese Bournonite (Kosnars) looks like ferberite to me !!



Keith Compton
16th Sep 2017 2:14pm
Keith, that was likely my mistake - I thought the same thing when I reviewed the report afterwards. Not sure why I mixed that up.
