3 New Can’t-Miss Collections at JCK Las Vegas 2025

By Victoria Gomelsky | May 07, 2025

One reason JCK Las Vegas remains such an important hub for the international fine jewelry trade is because the show offers a truly diverse range of products, from loose diamonds and gems to tech equipment and supplies. Even among jewelry manufacturers, the diversity is staggering. Fashion jewelry vendors, natural diamond sellers, quirky designers, big brands—the show floor has it all.

The three collections highlighted below offer a taste of JCK’s variety:

Haute Couture Brooch Collection by Smiling Rocks

Longtime JCK exhibitor Smiling Rocks is touting a new line of Haute Couture brooches featuring lab-grown diamonds in myriad hues. Brooches, if you haven’t heard, are having a moment. If Kendrick Lamar’s Super Bowl performance taught us anything, it’s that the once–old-fashioned accessory is riding a wave of interest, especially among style-conscious men.

The Periklista Collection by Kouzoupis

Kouzoupis, a Turkish exhibitor in the Design Collective, is introducing the Periklista collection, which is named for the ancient Greek enamel technique that lends the pieces both their color and style.

Like the European cloisonne method, the Periklista technique involves creating small partitions made of thin metal wires or strips on a metal surface, usually made of gold, and filling them with enamel, stones, or glass. Pioneered during the Mycenaean period (16th–12th century B.C.), Periklista enamel jewels were found in the royal tombs at Mycenae. Refined in subsequent centuries by Greek goldsmiths, the technique later influenced Roman and Byzantine art.

In Kouzoupis’ version, the ancient technique is made modern by the addition of bright colors and motifs, such as snakes, that capture the 2025 zeitgeist.

Kouzoupis pendant — *Periklista pendant in 18k yellow gold with 0.18 ct. t.w. diamonds and enamel, 2,400 euros (about $2,730);* *Kouzoupis*

La Perla by PDPaola

If you’re in search of fashionable, affordable pearls, make a beeline for the PDPaola booth in the Fashion Bridge neighborhood. In its new La Perla collection, the Barcelona-based brand, founded in 2015 by siblings Paola and Humbert Sasplugas, reimagines the classic pearl in contemporary settings that highlight the organic gem’s natural fluidity.
