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.

Exceptional Platinum Jewelry Designs Win AGTA Spectrum Awards Competition
More than 60 platinum jewellery entries competed for top honours, recognising exceptional craftsmanship, innovative designs and the versatility of platinum across coloured gemstones and pearl jewellery.
Platinum Guild International (PGI), in partnership with the American Gem Trade Association (AGTA), is pleased to announce the Platinum Honors winners of the 2026 AGTA Spectrum Awards.
More than 60 platinum jewelry entries were submitted to the Platinum Honors category, which recognizes outstanding uses of platinum in colored gemstone and natural or cultured pearl jewelry across multiple categories, from Evening Wear to Engagement Rings. PGI also traditionally presents an award for Best Use of Platinum and Color.
The AGTA Spectrum Awards competition was held at the Omni Frisco Hotel at the Star in Dallas, where Jenny Luker, President, PGI USA, judged the Platinum Honors category.
“The AGTA Spectrum Awards bring together an extraordinary range of platinum jewelry, and the level of design innovation, technical execution, and artistry is exceptional,” said Luker. “It’s exciting to see so many talented designers exploring the material in different ways, creating intricate, distinctive pieces that showcase the versatility of platinum.”
AGTA CEO John W. Ford Sr. thanked PGI for its sponsorship of the Spectrum Awards and extended his congratulations to the Platinum Honors winners. “Receiving a Platinum Honors distinction from PGI is one of the industry’s highest achievements,” he said. “We were happy to see Platinum so well represented among the AGTA Spectrum entries, which increased by 21% this year.”
Platinum’s potential for design innovation and technical accomplishment was exemplified by several of this year’s AGTA Spectrum Award winners.
The Best of Show award and 1st Place in Classical Wear was awarded to “Can’t Look Away,” a necklace by Lezlie Slavens of Luxe Fine Jewelry and collaborators. The design features a carved Paraiba tourmaline backed in platinum, suspended from a diamond-accented platinum chain and illuminated by a magnet-activated LED light source.
The Art Deco-inspired “Horus Egyptian Revival” bracelet by Joseph Dardashti, in Platinum with Rubies, Sapphires, Emeralds, Diamonds, and Onyx, won 1st Place in the Spectrum Awards’ Evening Wear category and also received a Platinum Honors distinction in the same category.
Jeffrey Bilgore’s Mahenge Spinel and Diamond “Neuvelle Moi et Toi Forever” Platinum ring received the Stuller Color of the Year Award, a new category honoring exceptional interpretations of Stuller’s “Signature Red”, and won 2nd Place in the Spectrum Awards’ Classical category.
The honour of 1st Place in the Bridal category went to Niveet Nagpal of Omi Gems, Inc. for his Platinum ring featuring a 5.32 ct. Paraiba Tourmaline, accented by Tourmaline (1.05 ctw.) and Diamonds (0.69 ctw.).
New entrant Shelby Lichtenstein was awarded 1st Place in Engagement Rings with her Platinum “Something New, Something Blue” ring, featuring a 4.50 ct. blue emerald-cut Zircon accented by Diamonds (0.26 ctw.).
“Because of platinum’s durability, strength, and tensile properties, designers can achieve things that might not be possible with other metals,” said Luker. “Whether it’s intricate micro pavé work or delicate prongs, platinum allows for exceptional precision while ensuring that gemstones remain secure.”
Across all categories of the Spectrum Awards competition, noteworthy platinum jewelry trends included bezel settings in engagement rings, designs that paired platinum with moonstones for a dreamy, elegant white-on-white effect, and brooches for both men and women that incorporated multiple gemstone types in an array of cuts and sizes.
“The level of design this year was incredible,” said Luker. “I was particularly impressed by the innovation and execution. Platinum plays such a wonderful supporting role to gemstones, and that relationship has endured—and will endure—forever.”
