7 Post-Tucson Predictions and Observations
Senior Editor Brecken Branstrator says spinel and garnet are hot while the end of the shows were not.

Tucson had a slightly different energy this year.
Was it because it was so cold and we didn’t get as much of the outdoor time as we’re used to? Did the current uncertain environment have everyone playing it a little safer when it comes to traveling and shopping?
I don’t really know but, even in its off years, Tucson still seems to be at the top of the work travel list for all who go.
The shows are more laid-back than others, you get the chance to see gemstones you’ve only ever heard of and there is, of course, the spectacular scenery in even the coldest of years.
I’m grateful to have been able to spend another fantastic week there for the annual gem shows. Here are a few insights I noted after walking the (many) show floors.
1. The shows seemed to end quieter than normal.
I spent my first day just walking around GJX and especially AGTA GemFair, chatting with people and looking at stones. The aisles during opening day, especially at GemFair in the convention center, seemed pretty busy.
My last full day in Tucson, that Saturday, I saved for just walking the shows again to get a feel for how things went, and it felt like a ghost town almost everywhere.
The last few days of the industry shows in Tucson generally feel slower, as attendees filter out to the other gem and mineral shows in different parts of the city, but this year felt different.
GemFair seemed quiet, but the aisles in GJX were fairly empty, and even weirder, when I ventured over to the Pueblo Gem & Mineral Show at the Ramada (which used to be the Riverpark Inn), I felt like I was one of the only people there.
Did people cut their trips back? Did they finish their shopping earlier? I’m not sure what the reasoning was, but luckily it didn’t seem to have too negative an effect on exhibitors, because …
2. People were still buying.
By the time the weekend rolled around, there had been plenty of time for shopping. So despite the quiet end, plenty of people still seemed happy, or at least “OK,” with how the shows turned out.
Despite an uneven holiday season and anxiety about whether the political climate will affect spending, it was still good to hear that attendees were, indeed, buying,
3. I love spinel and, it turns out, everyone else does too.
Was it just me, or did almost every exhibitor who was selling spinel say the gemstone was selling like hotcakes?
And it’s not just the beautiful pinks that people are lusting after; perhaps just as hot are the steely grays, gray-blues and gray-purples.

4. Garnets are on their way up.
A gemstone I think we can still call underrated is the garnet.
The gem comes in a rainbow of colors ranging from some of the most vivid oranges and greens found in the colored stone spectrum to the romantic purples, fuchsias and maroons.
Combine that with its (general) affordability, and the stone offers one of the best deals in the marketplace, in my opinion.

Could 2019 be a turning point for January’s birthstone? I, for one, sure hope so.
5. Two shapes stood out.
Cutting and shapes are really having a moment in the colored stone world; they’re another way for designers and brands to create unique pieces that set them apart.
For me, there were two favorites that popped up several times in Tucson this year: hexagon cuts and slices.
The latter isn’t new, as slices have been growing in popularity for a while now, but I loved to see several booths carrying stones with hexagon cuts. The shape adds interest and a cool factor to gemstones.

6. Edgy is in.
This point originates from a conversation I had with Kimberly Collins at GemFair; she used “edgier” to talk about trends in the market. I loved it so much I’m borrowing it here.
Buyers are turning to colored stones to help give their jewelry a story, true, but it’s going beyond that now.
They’re not only looking for great stones, but also now the cool cut, the interesting shape—like the Geocuts above from Columbia Gem House, which the company said generated a lot of interest in Tucson—or the color that’s seen nowhere else, and the sector is answering that demand.
We’ve known it for a while, but I’m happy to hear more people are starting to understand: Color is cool.
7. Collaboration is needed to unify responsible sourcing meaning and efforts.
One thing that will come as a surprise to no one: Tucson 2019 was buzzing with “responsible sourcing” discussions.
It seemed like every other panel, education session or conversation revolved around responsible sourcing efforts or needs.

The many conversations around responsible sourcing, ethical sourcing, sustainability and the like, are definitely a move in the right direction.
But now we’re at a place where I wonder: Are there too many separate conversations happening? Is it creating more confusion than aid, particularly when the vocabulary means different things to different people?
I think we’re at a critical point where the trade has to get on the same page.
We need to establish exactly what it would mean for a company or brand to be able to use “responsible sourcing,” “ethical sourcing” or “sustainability,” and in vocabulary that won’t risk pushing out any of the smaller players along the supply chain.
It’s critical for both the industry’s understanding and to help communicate the messaging with consumers.
