Emeralds announce spring’s arrival in Natasha Collis x Gemfields collaboration
Just in time for the start of Emerald Month in May – when green buds burst into life, lifting spirits – comes an exciting new collaboration from Gemfields. A world-leading responsible miner and marketer of coloured gemstones – and majority-owner and operator of the Kagem emerald mine in Zambia – Gemfields has joined forces with Ibiza-based jeweller Natasha Collis on two special collections designed to “bring joy to the everyday”. The Natasha Collis Fine Jewellery x Gemfields Ludic and Dancing Duet ranges showcase Gemfields’ Zambian emeralds offset against yellow gold in pieces that balance spontaneity and refinement. Inspired by the dualities of nature, they resound with the joys of spring. The four-piece Ludic collection consists of arresting 6cm drop earrings with oval, pear and round cut emeralds; a striking statement ring with an off-centre emerald; an open bangle with emerald pave; and a necklace with a chain of oval, pear and round emeralds.
Ludic is defined by its free-form shapes, a motif which also provides the design inspiration underpinning the Dancing Duet range. In this second collection, contrasting gold forms are placed two by two, creating an intimate duality of interconnected elements. The Dancing Duet range encompasses two necklaces, cascading Dancing Duet earrings, everyday studs and a beautifully flowing bracelet. Each of these features exquisite emeralds from the Kagem mine, set in sculpted 18k gold pieces, locked together in a graceful dance of playful opposition.

“My love for emeralds combined with Gemfields’ brand ethos inspired me to create this collaboration,” says Natasha Collis, who founded her eponymous fine jewellery brand in London before relocating in 2009 to Ibiza, where she now has a boutique and studio in the rugged North of the island and takes design inspiration from nature. A trained painter, Natasha switched her focus to jewellery design, experimenting with gold and different creations, and she has never looked back.
Her signature style highlights the raw beauty of gold: hand-crafting nuggets into organic shapes, with carefully selected asymmetric gemstones incorporated in a quirky and playful way. Natasha’s designs are, at once, wearable works of art and perfect for layering into every day. Gemfields believes those who mine gemstones should do so with transparency, legitimacy and integrity and that coloured gemstones should create a positive impact for the country and community from which they originate. Kagem – 75% owned by Gemfields in partnership with Zambian government – is believed to be the world’s single largest-producing emerald mine and has been the source of some of the most exceptional emeralds ever seen. “Natasha Collis’ organic, free-flowing designs take us to Ibiza! In these beautiful collections, Zambian emeralds provide pops of green and sparkle, effortlessly elevating a look and demonstrating the playful quality of coloured gemstones. Each emerald is a miracle of nature, having formed over 500 million years ago in the most unlikely of circumstances. Their rarity and unique characteristics set them apart, and make them the perfect choice for collections that are lively, and full of fun,” says Gemfields’ Marketing and Communications Director, Emily Dungey. With emerald the resplendent birthstone of May, it is timely to see Kagem’s treasures take pride of place in these one-of-a-kind designs by Natasha.

De Beers Group Reports H1 2026 Production Surge
The company reported a significant increase in production volume while maintaining its full-year production target of 21 to 26 million carats.
De Beers Group today released its operational and sales performance update for the second quarter and first half of 2026. Driven by strong recovery efforts and strategic access to higher-grade ore bodies, the company reported a significant increase in production volume while maintaining its full-year production target of 21 to 26 million carats.
Despite market pressures stemming from broader macroeconomic volatility, the company continues to advance operational streamlining and cost-optimization initiatives to ensure long-term resilience.
Key Highlights & Operational Summary
- Q2 Production Surge: Production jumped 88% year-on-year to 7.8 million carats in the second quarter, bringing total H1 output to 14.9 million carats (+46% YoY).
- Volume Growth: Consolidated H1 sales volume expanded 13% to 12.4 million carats (total sales volume up 20% to 14.8 million carats).
- Full-Year Guidance Reaffirmed: Full-year output remains targeted at 21–26 million carats, with second-half production planned to balance out via scheduled maintenance and a temporary operational pause at the Venetia mine.
- Resilient High-Value Demand: While entry-level categories faced broader pricing shifts, pricing for higher-value natural diamonds remained firm, providing baseline support to the overall index.
Market Dynamics & Strategic Response
Trading conditions during the first six months of 2026 reflected ongoing global macroeconomic uncertainties and regional conflicts that weighed on general consumer sentiment. Additionally, lower-value natural categories experienced continued pressure from lab-grown alternatives.
In response, De Beers actively adjusted its sales strategies, utilizing its inventory mix to meet existing market demand. While lower-value inventory sales shifted the average realized price to $105 per carat for H1, the company noted that underlying value indices for premium, higher-grade natural goods remained stable throughout the period.
Outlook & Portfolio Optimization
Looking ahead to the second half of 2026, De Beers will align production output directly with global demand signals. The anticipated surge from H1 will be offset by:
- The previously announced two-year operational pause at the Venetia mine.
- Planned facility maintenance at the Orapa and Jwaneng operations in Botswana.
Anglo American continues to execute its operational transformation and strategic divestment plans for De Beers, ensuring capital discipline and long-term organizational value.
