AGTA previews birthstone gems and finished jewelry for GemFair Las Vegas

The clearest signal from AGTA’s Las Vegas calendar is that birthstone jewelry is no longer being treated as a side note. At GemFair Las Vegas, opening May 28 at the Venetian Expo, buyers will find responsibly sourced natural colored gemstones, natural pearls and cultured pearls, all backed by AGTA’s enforced Code of Ethics. With JCK Las Vegas following May 29 to June 1 at the same venue, GemFair is setting the tone for what color will look like on the market before the wider buying crowd arrives.

That matters for birthstones, because AGTA’s own 2026 editorial run has already mapped out the stones that are likely to matter most to custom clients and retail floor planners. January brought garnet, March aquamarine, April diamond and May emerald, each framed through finished jewelry as well as loose stones. The mix suggests a healthy pipeline for designs that are already assembled and ready to wear, not just parcels waiting for a bench. Names such as Yael Designs, Omi Gems, Sparkles & Colors USA Inc., Rio Diamond Corp., Zaffiro Jewelry, Misfit Diamonds and Oscar Heyman & Brothers place craftsmanship alongside material, which is exactly how birthstone buying has shifted: the setting now carries as much weight as the stone.

The strongest availability appears to be in garnet and aquamarine, where AGTA has already shown a broad range of finished pieces. That points to a category where shoppers should expect better selection and less of the frantic scarcity that can define the finer end of colored-stone buying. Diamond, meanwhile, remains the safest of the birthstones in terms of recognition and depth of inventory, but it is also the most crowded lane, which means the pieces that stand out will be the ones with better design discipline, sharper proportions and cleaner setting work.

Emerald is the stone that looks most likely to move upmarket. AGTA’s May birthstone post highlighted a 13.91 ct. Colombian sugarloaf-cut emerald ring from Oscar Heyman & Brothers, a detail that says everything about where the conversation is headed: provenance, size and cut are doing the heavy lifting. For clients who want a birthstone with immediate presence, emerald invites commissioning rather than casual buying, especially if the goal is a ring or pendant that feels singular rather than standard.

AGTA’s annual Las Vegas Membership Meeting, scheduled for Monday, June 1, at 8:30 a.m. PT in the AGTA Pavilion, Booth A30058, reinforces how central the show remains for the colored-stone trade. For birthstone jewelry, the message is crisp: garnet and aquamarine look ready for strong selection, diamond remains dependable, and emerald is the one to watch for a more exclusive, more expensive turn.
