The third London Gem & Mineral Show, which took place on November 22-23, 2025, experienced a notable turnout, drawing in a diverse crowd of industry professionals, collectors, and hobbyists. The event showcased a consistent, albeit gradual, market for colored gemstones, emphasizing the strong appeal of non-treated precious stones. Dealers observed a particular enthusiasm for brightly colored and pastel-hued gems, with Gemstones of East Africa reporting robust sales for tsavorite and mandarin spessartite. The rising cost of precious metals has also shifted consumer interest towards more budget-friendly colored gemstones, especially within the bespoke jewelry sector, as highlighted by industry experts. A panel discussion moderated by Jewellery Outlook Editor David Brough explored key trends and influences shaping the colored gemstone market, featuring insights from prominent figures in the auction and retail segments.

Overall, the exhibition reinforced the dynamic nature of the gemstone and mineral trade, underscoring the continuous demand for unique and ethically sourced materials. The show provided a vital platform for networking and knowledge exchange, solidifying its position as a significant event in the industry calendar. The discussions underscored the challenges and opportunities in sourcing and marketing gemstones, with a clear focus on adapting to evolving market conditions and consumer preferences.

High Attendance and Market Insights at the London Gem & Mineral Show

The latest edition of the London Gem & Mineral Show, held on November 22-23, 2025, recorded a robust attendance, bringing together a wide array of participants from the retail sector, private collectors, and gemstone enthusiasts. The event served as a crucial meeting point for sourcing and exchanging various precious items, including gems, minerals, freshwater pearls, beads, and fossils. Exhibitors noted a stable, yet gradually evolving, market for colored gemstones, with a particular focus on the supply constraints of high-end, non-treated precious stones. The vibrancy of bright colors and subtle pastel tones proved especially popular among buyers. Ali Mawji of Gemstones of East Africa highlighted a growing demand for vivid green tsavorite and mandarin spessartite, attributing this trend to a resurgence in the medium-tier market over the past six months, with gemstones directly sourced from Tanzanian mines ensuring responsible practices.

The show's success was further enriched by insightful discussions on market dynamics. Industry leaders, including Arya Marafie from Mayfair Gems, pointed out a significant shift towards lower-value colored gemstones in bespoke jewelry designs. This change is largely driven by the increasing prices of precious metals, which has impacted the overall affordability of jewelry pieces. A key event was a panel discussion, moderated by Jewellery Outlook Editor David Brough, which delved into the primary drivers and emerging trends within the colored gemstone markets. The panel featured distinguished speakers such as Kristian Spofforth, Consignments Director at Heritage Auctions; Tamara de Rezende Leifheit, Business Development Manager at Nivoda; and Alexander Davis, a renowned fine jewelry retailer and designer-maker. Their collective expertise offered valuable perspectives on the current state and future trajectory of the gemstone industry.

Key Trends and Panel Perspectives on Colored Gemstones

The third London Gem & Mineral Show provided a comprehensive overview of the current landscape in the gemstone market, marked by a strong turnout of retailers, collectors, and hobbyists. A consistent and moderately active market for colored gemstones was observed, with a particular emphasis on the limited availability of high-quality, untreated precious gemstones. The demand for vibrant and subtly shaded gemstones remained strong, with notable interest in vivid green tsavorite and mandarin spessartite, as reported by Gemstones of East Africa, a company known for its direct and responsible sourcing from Tanzanian mines. This highlights a growing consumer preference for both visually appealing and ethically obtained materials.

A significant highlight of the show was the panel discussion, expertly guided by David Brough, Editor of Jewellery Outlook. The discussion centered on critical factors influencing the colored gemstone market and anticipated future trends. One key insight shared by Arya Marafie of Mayfair Gems was the increasing preference for more affordable colored gemstones in bespoke jewelry. This trend is a direct consequence of the escalating prices of precious metals, which has made consumers more conscious of the overall cost of their jewelry acquisitions. The panel featured prominent industry figures such as Kristian Spofforth of Heritage Auctions, Tamara de Rezende Leifheit from Nivoda, and independent jewelry designer Alexander Davis. Their diverse backgrounds and expertise offered a multifaceted examination of market challenges and opportunities, including discussions on sourcing, consumer behavior, and innovative design approaches within the colored gemstone sector. The collective insights underscored the importance of adaptability and strategic innovation for businesses operating in this dynamic market.
