Every February, the global gemstone industry gathers in Tucson, Arizona, for one of the most important annual meetings of gem dealers, cutters, designers and collectors.

The 2026 Tucson shows offered an unusually revealing snapshot of where the colored gemstone market is heading. At the AGTA GemFair, Gem & Jewelry Exchange (GJX) and other major venues, buyers showed particularly strong interest in exceptional color, unusual gemstones, precision cutting and documented provenance.

While overall attendance varied between venues, premium stones at attractive prices continued to sell quickly. More importantly, the market showed a clear preference for quality over quantity: buyers increasingly looked for gemstones with distinctive color, strong cutting performance and a traceable story from mine to finished jewel.

For Hong Kong collectors and fine-jewellery buyers, Tucson offers an early indication of the gemstone stories that may become increasingly relevant across the Asian luxury market.

A Strong Tucson Market Despite Uncertainty

The 2026 Tucson shows began against a complicated market backdrop.

At AGTA GemFair, held from February 2–6, many vendors reported exceptionally strong opening-day sales. Some exhibitors even found themselves struggling to meet demand with the staff available.

At GJX, the pattern was slightly different. Monday was reportedly quieter, but attendance increased on Tuesday as higher-end buyers completed their AGTA shopping and moved to the other venues.

Premium and unusual pieces were particularly successful.

One notable example was a finely carved nephrite jade alligator from the Polar mine in British Columbia, which sold quickly at GJX. Its appeal illustrates an important characteristic of today's luxury gemstone market: collectors are not necessarily looking only for conventional faceted stones. Exceptional craftsmanship, rarity, provenance and individuality can be equally powerful.

Meanwhile, foot traffic at several other Tucson venues appeared somewhat lower. Yet vendors offering premium-quality material at compelling prices continued to report brisk sales.

This suggests that the market may be becoming more selective.

Buyers are willing to spend—but increasingly want a compelling reason to do so.

Provenance Is Becoming Part of the Luxury Story

One of the clearest themes emerging from Tucson 2026 was the increasing importance of provenance documentation.

For a luxury gemstone, the story does not necessarily end with its color and carat weight.

Where did it come from?

Was it treated?

What geological environment produced it?

Can its journey from rough material to finished gemstone be documented?

These questions are becoming increasingly important as sophisticated buyers become more interested in rarity and traceability.

GIA itself has invested extensively in field gemology and reference collections to better understand gemstone origins. Its research on colored stone origin determination is one reason geographic provenance has become such an important part of modern gemstone reporting.

This matters particularly for gemstones where origin can have a significant influence on desirability.

Think of:

• Kashmir sapphire

• Burmese ruby

• Colombian emerald

• Montana sapphire

• Paraíba tourmaline

• Mozambique ruby

• Sri Lankan sapphire

For collectors, origin can become part of the identity of the stone.

And in the luxury market, identity matters.

Fancy-Color Sapphire Takes the Spotlight

Among the many gemstones presented at Tucson, fancy-color sapphires were reported to be among the strongest performers.

The most popular colors included:

• Hot pink

• Purple

• Teal

• Green

• Greenish blue

This is particularly interesting because it reflects a broader movement away from the idea that sapphire must simply mean "classic blue."

Modern collectors are increasingly interested in the entire sapphire color spectrum.

A vivid pink sapphire can create an entirely different emotional impression from a deep royal blue.

A teal sapphire can sit somewhere between blue and green, offering a more contemporary character.

Green sapphire can provide an earthy alternative to emerald.

And purple sapphire can create a romantic, unconventional statement.

For designers, this expanded palette creates enormous creative potential.

Rather than beginning with a traditional gemstone category, today's jewellery design can begin with color itself.

Montana Sapphire: Rarity Meets Growing Global Demand

Montana sapphire deserves particular attention.

According to exhibitors at Tucson, strong demand from both U.S. and international buyers has pushed prices for Montana sapphires above 1 ct to exceptional levels.

The combination of increasing global awareness and unpredictable availability of rough material has contributed to this pressure.

Montana sapphire is particularly appealing because of its distinctive range of colors.

Blue, green, teal and blue-green stones can create a natural, understated aesthetic that feels particularly relevant to today's preference for individuality.

Unlike a traditional diamond-centered approach, a Montana sapphire engagement ring or cocktail ring can communicate a much more personal point of view.

For Hong Kong buyers who want something less conventional, this is a gemstone worth watching.

Ruby, Star Sapphire and the Return of Phenomenal Gems

The Tucson market also demonstrated strong interest in gemstones whose appeal comes from optical phenomena, rather than color alone.

Star ruby and star sapphire were among the hottest items reported at the shows.

These stones display asterism—a star-like optical effect that moves across the surface of the gemstone under suitable lighting.

Cat's-eye stones were another strong category.

Cat's-eye moonstone in particular was offered at several venues at attractive prices. The visual phenomenon known as chatoyancy can create a sharp band of light that moves across the gemstone, producing an effect that changes as the stone or light moves.

This creates a different kind of luxury.

Instead of maximizing sparkle, the gemstone becomes something to observe.

Its beauty changes with movement.

This category is particularly interesting for collectors because phenomenal gemstones can feel almost like natural optical artworks.

Rainbow Moonstone and the Continuing Appeal of Optical Effects

Another gemstone continuing to attract buyers was the material commonly marketed as “rainbow moonstone” from Madagascar.

GIA previously documented high-quality material from Madagascar displaying strong blue adularescence together with flashes of other colors, including orange. GIA's research identified this material as a plagioclase feldspar within the labradorite variety.

At Tucson 2026, this material continued to sell quickly.

Its popularity is understandable.

The gemstone combines a relatively soft, ethereal body appearance with dramatic flashes of color that can change according to viewing angle.

This is another example of the market's movement toward gemstones that do something visually interesting.

Collectors increasingly appear willing to look beyond conventional brilliance in favor of stones that create movement, color change, adularescence or chatoyancy.

Ethiopian Opal: Abundant Today, Potentially Scarcer Tomorrow

Ethiopian opal was widely available throughout the Tucson shows, particularly as rough and loose material at the 22nd Street show.

Prices varied considerably, creating opportunities for buyers at different levels.

But GIA's report also highlights a potential warning sign: supplies of easily accessible material from the Wollo region are becoming increasingly limited.

If availability continues to decline, prices could begin to rise.

This illustrates one of the most important principles for gemstone collectors:

Abundance at a trade show does not necessarily mean unlimited future supply.

A gemstone can appear widely available during a particular market cycle while its underlying rough supply is becoming increasingly constrained.

For collectors, understanding the relationship between current availability and geological supply can be more useful than simply looking at today's retail price.

Labradorite and the Rise of Unexpected Color Combinations

Labradorite was another material attracting attention.

A Madagascar variety with a gray matrix and pink flash appeared at venues including the Pueblo and 22nd Street shows.

The combination is interesting because it demonstrates how modern gemstone appeal increasingly comes from unusual color relationships.

Instead of seeking perfectly uniform color, designers can embrace:

• Matrix

• Inclusions

• Color flashes

• Zoning

• Natural textures

This is particularly relevant to contemporary jewellery design.

Luxury does not always mean flawless.

Sometimes the feature that makes a stone memorable is precisely the characteristic that makes it impossible to reproduce perfectly.

The Color Palette of 2026

If Tucson 2026 had one dominant visual language, it was undoubtedly color.

The strongest trending colors included:

• Hot pink

• Purple

• Neon blue-green

• Light green

• Teal

• Greenish blue

• Lilac

The AGTA Spectrum and Cutting Edge Buyer’s Choice Awards reflected this vibrant palette.

One standout combination was pink and purple kunzite, while another award-winning piece combined vivid pink with other saturated gemstones.

A newer material that attracted attention was Guatemalan blue jadeite jade.

Its teal coloration resembled the color range of some highly sought-after unheated Montana sapphires.

For Hong Kong's luxury jewellery market, this could be particularly significant.

The city's sophisticated buyers are already accustomed to exceptional diamonds and traditional precious gemstones. Distinctive color provides another way to express individuality.

Precision Cutting: Why Buyers Are Choosing Beauty Over Carat Weight

One of the most important trends at Tucson was not a particular gemstone.

It was how gemstones were being cut.

Buyers showed strong interest in stones designed to maximize light return and color rather than simply carat weight.

The term "precision cutting" was used somewhat differently among vendors, but buyers consistently valued:

• Sharp meet points

• Precise facet junctions

• Appropriate cutting angles

• Strong light return

• Flat, mirror-finish facets

This represents an important shift in the way sophisticated buyers evaluate gemstones.

A larger stone is not automatically a better stone.

A smaller gemstone with exceptional proportions, symmetry and optical performance can be considerably more beautiful.

That philosophy is especially relevant when selecting a gemstone for a bespoke jewellery piece.

 

---

 

Unconventional Cuts Bring an Architectural Edge

Tucson also revealed growing interest in cutting styles outside conventional rounds, ovals and cushions.

Star-shaped gems were particularly popular.

Examples included Montana sapphire, neon beryl, red Idaho garnet and quartz cut into star forms.

Other unconventional styles included:

• Cubes

• Cones

• Geometric slabs

• Long baguettes

• Architectural shapes

Polished gemstone slabs in rectangles and triangles also attracted attention from designers.

These shapes are particularly interesting for contemporary jewellery because they allow the gemstone itself to become part of the architecture of the design.

Provenance, Cutting and Color: The New Luxury Equation

Looking across the Tucson 2026 market, three characteristics stand out:

Color.

Cut quality.

Provenance.

These factors are increasingly working together.

A gemstone does not need to be enormous to attract attention.

A 1.5 ct sapphire with exceptional color, precision cutting and documented origin can be more compelling than a much larger but ordinary stone.

This is particularly relevant to the collector market, where rarity is multidimensional.

Rarity can come from:

• Geological origin

• Color

• Size

• Lack of treatment

• Optical phenomenon

• Exceptional cutting

• Historical provenance

This broader definition of rarity is one reason colored gemstones continue to occupy such an important place in high jewellery.

What Tucson 2026 Means for Hong Kong Jewellery Buyers

Tucson is not simply a trade show.

It is a snapshot of the global gemstone supply chain.

The 2026 event suggests that buyers remain willing to spend on exceptional material, even as the industry faces higher metal prices, tariffs, supply concerns and changing international trade patterns.

For Hong Kong buyers, several trends are worth watching closely.

1. Fancy-color sapphire is becoming increasingly important

Pink, purple, teal and green sapphires offer alternatives to conventional blue.

2. Provenance matters more

Documentation of origin and treatment can increasingly become part of a gemstone's luxury value.

3. Precision cutting matters

Collectors are becoming more sophisticated about evaluating optical performance rather than simply carat weight.

4. Phenomenal gemstones remain compelling

Star sapphire, star ruby and cat's-eye stones provide visual effects that conventional faceted stones cannot reproduce.

5. Unusual color combinations are gaining attention

Teal, lilac, hot pink and neon blue-green are expanding the visual vocabulary of fine jewellery.

The Future of Colored Gemstones Is More Personal

Perhaps the most interesting conclusion from Tucson 2026 is that there was no single viral gemstone dominating the entire market.

Instead, the market was remarkably diverse.

That may actually be a sign of a healthier luxury environment.

Buyers were choosing gemstones based on individual color preferences, cutting quality, rarity and provenance rather than following one universally dominant trend. GIA similarly concluded that while no major new viral product emerged, vendors offered a broad selection of attractive colored gems with a strong emphasis on cut quality and provenance documentation.

For the modern collector, that creates opportunity.

You do not necessarily need to buy the gemstone everyone else is buying.

You can look for the stone that has the right combination of color, character, craftsmanship and story.

Final Thoughts: What Should You Watch After Tucson 2026?

The 2026 Tucson shows reveal a colored gemstone market that is becoming more selective, more design-conscious and increasingly interested in provenance.

Fancy-color sapphires are commanding attention.

Montana sapphire is benefiting from growing international demand.

Star stones and cat's-eye gems continue to attract collectors who value optical phenomena.

Ethiopian opal and Madagascar rainbow moonstone demonstrate how supply and unusual optical effects can influence desirability.

And perhaps most importantly, precision cutting is becoming a bigger part of the conversation.

For today's luxury jewellery buyer, the most desirable gemstone is not necessarily the largest.

It may be the one with the most compelling combination of color, light, origin and individuality.

For collectors in Hong Kong, this makes 2026 an especially interesting time to explore colored gemstones beyond the traditional blue sapphire, ruby and emerald.

At Mangrove Diamonds, buyers can explore gemstones selected not only for their specifications, but for the character and visual identity they bring to a finished piece of jewellery.

The next generation of gemstone luxury may not be about owning what everyone wants. It may be about discovering what nobody else has.
