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. These collections highlighted below offer a taste of JCK’s variety:Haute Couture Brooch Collection by Smiling Rocks, Smiling Rocks guitar brooch and  The Periklista Collection by Kouzoupis.

Haute Couture Floral Guitar brooch in 14k yellow gold with 0.98 ct. t.w. lab-grown diamonds and enamel,; Smiling Rocks. Haute Couture Hummingbird brooch in 14k white gold with 4.6 cts. t.w. multicolored lab-grown diamonds. 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. 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.

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.
