7 Expectations for the Tucson Gem Shows
Exhibitors dish on the gemstone colors, qualities and cuts that will be hot in the desert.

New York—In two weeks, many in the industry will be packing their bags for the desert.
The gem, mineral and jewelry shows that take over Tucson in late January-early February now number more than 50, according to online guides, though most in the trade have a handful they frequent.
The American Gem Trade Association’s GemFair is slated for Feb. 5 to 10 in the Tucson Convention Center. A few changes have been made to the jewelry trade show this year, including new and expanded exhibits of gemstone jewelry designers in the upgraded Grand Ballroom.
GJX also is slated for Feb. 5 to 10, just across South Granada Avenue from GemFair.
There also are dozens of other shows across the city, including JCK Tucson at the JW Marriott Tucson Starr Pass Resort & Spa (running Feb. 6 to 9), JOGS (Jan. 31 to Feb. 11), and the Pueblo Gem & Mineral Show (Feb. 1 to 13).
National Jeweler asked a handful of gemstone dealers exhibiting at the upcoming shows what they’re expecting in terms of color, stone and pricing trends.
Here are seven things they noted.
1. Demand for red, pink, purple and even orange is hotter than ever.
This color trend has carried over from the past few years in Tucson, with exhibitors reporting warm hues of spinel, sapphire and garnet were flying out of their showcases.
It appears 2019 isn’t going to be any different.
Jeremy Chalchinsky of Color Source Gems said ever since morganite became popular, it has lifted pinks, oranges and “sunset colors” into the mainstream jewelry market.
“We’ve seen lots of demand for that, whether it’s imperial topaz, padparadscha sapphire or Malaya garnet,” he said. “While the trend seems to be leveling off a bit, we can expect the increased recognition to lead to greater sales down the road.”
He added that purple also has become popular, with a noticeable uptick in purple sapphire sales.
“Tucson will be the test as to whether that’s going to continue strong into the rest of 2019.”
Robert Van Wagoner of Beija-Flor Gems noted, too, that reds and pinks are still very popular for him, while Nomad’s Josh Saltzman told National Jeweler that anything with a red, pink or lavender color always is in demand.
For Out of Our Mines, “more earthy-toned gems” seem to be rapidly gaining popularity, Richard Shull said.

2. Blues too.
Blue tones are so classic it’s not likely they’ll ever go out of style, but several exhibitors still are talking about how they expect blue gems to be hot in Tucson.
Van Wagoner said this is particularly true when it comes to the blues of a sapphire, or the “electric turquoise blues” of Paraiba tourmaline and the more budget-friendly Peruvian blue opal.
Saltzman of Nomad’s noted that fine aquamarine has been selling, a spike he attributed to the royal wedding (Meghan Markle wore Princess Diana’s emerald-cut aquamarine Asprey ring to the reception) and expects to continue this year.
He added that “lagoon” tourmaline—featuring a 50/50 mix of blue and green without any yellow tones—has been very popular in the last year. What’s more, there’ s very little of it on the market so he expects demand to continue.

3. The story of unique, rare and phenomenal stones continues.
In today’s market, unique and rare stones help designers and jewelry stores set themselves apart, and demand for gemstones that are hard to find continues to rise.
“Color’s really the place where stores are looking to set their individuality, and it’s where they can make money as well,” colored stone dealer Jeff Bilgore said, adding that he believes exotic, rare stones will do well this year.
Van Wagoner said foreign customers especially are focused on rare and unique stones, specifically cobalt blue spinel from Vietnam and a “screaming” pinkish-red spinel from the Man Sin mine in Mogok, Myanmar. (Some in the trade refer to this material as “jedi” spinel.)
Joining spinel in popularity among Van Wagoner’s buyers are Paraiba tourmaline, hyalite opal, Colorado rhodochrosite, red beryl and benitoite.
Saltzman also believes in spinel’s staying power, especially given how the supply issues in Tanzania over the past year—the Mahenge area was closed for much of the second half and the country instituted a ban on exporting rough—have limited the amount of material on the market even as demand stays high.
He also said the influence of social media is helping drive demand for lesser-known stones. Facebook and Instagram have allowed consumers to “discover” more, creating desire for rhodolite and Malaya garnet, bi-color gemstones and more.
Chalchinsky said Color Source Gems also has seen greater interest in unique gemstones that many consumers hadn’t heard of five years ago.
“That market is definitely growing, and Tucson is the place to find it.”
And, with the current tastes of new jewelry buyers and artists, Chalchinsky said there has been an increase in demand for spinel, tourmaline, zircon, and fancy or “parti” sapphires, reffering to those with two more colors.
They’re hoping these markets will continue to grow and spur new interest in colored stones.
4. A few specific factors will receive more attention.
Today’s discerning buyers are starting to look beyond just color.
This year, Van Wagoner predicted, buyers will pay more attention to treatments and their disclosure.
“Given how many treatments there are these days, disclosure is more important than ever, and retailers are increasingly concerned with how they will be able to present that information to their customers and to making sure they have all the information.”
BiIgore, meanwhile, is predicting even greater use of buzz words like “responsible sourcing,” “ethical sourcing,” and “sustainability,” both from exhibitors and from buyers looking for gems with a story.
Shull said as buyers look more for ethically sourced gems, stones with provenance will become a major staple in the industry, including American- and ethically-mined gems.
Chalchinsky, Saltzman and Shull are predicting a focus on cuts, albeit different kinds.

“Better cutting is a way to give stones the edge because quality cutting means better light return,” he said. “While always an integral part of the 4Cs, it’s starting to subtly become more important.”
Saltzman said Nomad’s sees high demand for bi-color gems cut in non-traditional styles, but also noted strong demand for traditional shapes and styles, like Asscher and emerald cuts, in all the gems the company supplies.
5. The two-tier market will continue.
What will become of the two-tier market that’s dominated the colored stone sector for a while, where expensive high-end stones as well as the lower end are selling with very little movement in the middle? According to these exhibitors, not much will change with it right now.
Van Wagoner said the higher end and lower end will both “really sell” in Tucson.
He also noted prices for mid-range goods will soften as the middle tier slowly dissipates; the retailers who were buying that material have moved down to the lower end of the market, toward goods such as beads.
Bilgore, too, thinks the two-tier market will continue into Tucson, with fine quality gemstones doing especially well, particularly when it comes to the fine spinel, rubies, sapphires and emeralds that have been popular.

6. Pricing should hold firm for fine goods.
High-end gemstones continue to sell so, not surprisingly, prices of fine material are expected to hold.
Van Wagoner said prices of lesser quality goods, meanwhile, will probably drop during the shows, and there likely will be some “screaming deals” to be found.
Overall, though, he expects prices to be up slightly, as does Nomad’s Saltzman and Shull from Out of Our Mines.
“I’m seeing pricing being similar to last year, with the exception of some rare stones that are no longer being produced,” Shull said. “They always seem to go up a bit each year.”
Bilgore predicted the same for Tucson: There will be firm pricing on fine goods, while exhibitors likely will be willing to negotiate on lower-end merchandise.
Chalchinsky said while many people have been returning from buying trips and reporting strong prices, he noted there are still great deals on loose stones and jewelry to be found.
“Prices should overall be consistent with last year, regardless,” he added.
7. There’s a lot in flux right now, but exhibitors still are optimistic.
Both in the United States and internationally, there are political situations that could affect buying activity, like the U.S. government shutdown, the trade war between the U.S. and China and the uncertainty surrounding Brexit.
Still, the exhibitors National Jeweler spoke with seemed to be optimistic about the shows in the desert.
“The current situation globally is a bit shaky overall, but we have continued to see solid demand from all our main markets, and I have heard from quite a few of our customers who are still planning to travel to Tucson to buy this year,” Saltzman said.
Tucson provides the perfect timing for jewelers to restock after the holiday season and re-evaluate inventory needs, Bilgore said.
“It’s an environment that’s happy and is so dynamic that people get excited by purchasing things that aren’t necessarily on their lists. I think that if people were going to spend anywhere, it will be in Tucson.”
Bilgore said many jewelers’ sales were up during the holiday season, even if only slightly, continuing a slow trend upward. And though he added that the current environment feels like post-election 2016 and provides an added unknown, stores might start out cautious in Tucson but end up buying more than expected.
Van Wagoner, meanwhile, said he thought the fourth quarter was weak for many jewelers, yet he believes they will be ready to spend when they get to the desert.
“I’m usually a little apprehensive about how the show is going to go. Historically, it’s been a pleasant surprise for me every time,” he said. “I’ve had a lot of people reaching out to me before, which is a good sign, but there are still a lot of variables right now.”
