Must -see collections at JCK Las Vegas 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. 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.

London Diamond Bourse Announces Launch Of Its New Coloured Gemstone Course
This Intensive One-Day Professional Development Initiative Provides Jewellery Retailers, Frontline Sales Teams, and Trade Professionals With Actionable Product Insight.
In response to shifting market dynamics and surging consumer demand for coloured gemstones, the London Diamond Bourse (LDB) has announced the strategic expansion of its educational framework with the launch of its new Coloured Gemstone Course.
Designed to complement the LDB’s established Practical Diamond Knowledge Course and Diamond Manufacturing Course, this intensive one-day professional development initiative provides jewellery retailers, frontline sales teams, and trade professionals with actionable product insight. The curriculum is specifically curated to enhance client engagement, streamline customer consultation, and support overall retail performance in an increasingly competitive market.
Key Market & Strategic Insights
- Market Diversification: Driven by a growing consumer preference for bespoke and individualised jewellery, coloured gemstones have emerged as a critical growth driver alongside traditional diamonds.
- Margin & Revenue Potential: Expanding gemstone inventory allows retailers to differentiate their product lines and capture higher-margin opportunities.
- Frontline Capabilities: The course directly addresses the trade’s critical need for heightened expertise in gemstone evaluation, quality factors, and value communication at the point of sale.
“Coloured gemstones are as much an integral part of the London Diamond Bourse as diamonds,” stated Charlotte Rose, President of the London Diamond Bourse. “Education is at the heart of everything we do, so we’re delighted to expand our education programme with the introduction of our new Coloured Gemstone Course—a one-day course that gives professionals an introduction to the fascinating world of gemstones and the practical knowledge and confidence to sell them with expertise.”
Inaugural Session & Promotional Launch
The inaugural session will take place on 3 August 2026 at the LDB headquarters in London’s historic Hatton Garden jewellery quarter.
To mark the strategic launch, the LDB is making four complimentary delegate places available (valued at £300 per seat) via a trade engagement initiative on Instagram. Participants can enter by following the official London Diamond Bourse account, engaging with the designated launch post, and commenting with their preferred gemstone. Winners will be formally announced on 28 July 2026.
