Discover Chatham’s ethical lab-grown gemstones — emeralds, rubies, sapphires and more. Learn why Lily Arkwright is the UK’s trusted leader in Chatham gems.
The future of fine jewellery is bright, colourful and responsibly grown. At the forefront of this movement are Chatham gemstones, pioneers in the field of lab-grown coloured gems that combine science, sustainability and timeless beauty.
Chatham’s creations — from radiant emeralds to fiery rubies and velvety sapphires — are chemically, optically and physically identical to mined stones, yet produced without the environmental and ethical impact of traditional extraction. The company’s founder, Carroll Chatham, began developing lab-grown emeralds in the 1930s, making Chatham a name synonymous with innovation and integrity
In Britain, Lily Arkwright has become the leading retailer of Chatham gemstones. Their collections offer UK buyers access to the full Chatham range, backed by ethical sourcing, transparent craftsmanship and exceptional design.
As BBC Culture notes, modern jewellery is increasingly valued not only for beauty but for conscience — and Chatham’s stones represent both.
Emeralds: The Colour of Renewal
Among Chatham’s most iconic creations are its lab-grown emeralds. Their vivid green hue, clarity and fire rival the best natural stones, yet are achieved through a controlled hydrothermal growth process that ensures consistency and purity.
According to Vogue UK, emeralds symbolise renewal and rebirth, making them especially popular for engagement rings and heirloom jewellery. At Lily Arkwright, customers can explore a selection of Chatham emeralds in various shapes — from classic emerald cuts to pear and round designs — all certified and ethically sourced.
These stones are perfect for buyers seeking depth, colour and conscience in equal measure.
Rubies: Passion and Precision
The ruby remains a timeless expression of love and strength. Chatham’s lab-grown rubies capture the intense “pigeon’s blood” red associated with the world’s finest natural rubies.
By growing their rubies in laboratory conditions, Chatham eliminates the ethical uncertainties of mining while achieving remarkable clarity and saturation. The Guardian Lifestyle highlights that responsible luxury is now a key motivator among younger British consumers, and lab-grown rubies perfectly match this new ethos.
Lily Arkwright offers a curated range of Chatham rubies that balance beauty with integrity. Each piece comes with certification and a lifetime warranty, making it as enduring as the emotion it represents.
Sapphires: A Spectrum of Modern Elegance
While blue sapphires remain the most recognisable, Chatham produces an entire spectrum of sapphire colours — from delicate pinks and sunny yellows to rare padparadscha tones.
BBC Culture has noted that coloured gemstones are redefining engagement traditions, with British couples embracing individuality over convention. Chatham’s sapphires exemplify this movement, offering beauty and symbolism without compromise.
Shoppers can view Lily Arkwright’s Chatham sapphire collection, which showcases these exquisite stones in multiple cuts and hues. The craftsmanship highlights how sustainability can coexist with luxury and romance.
Spinel and Other Rare Varieties
Beyond the classic gemstones, Chatham also cultivates more exotic stones such as spinel, alexandrite and aquamarine. These gems offer collectors and jewellery lovers distinctive alternatives, each with their own symbolic story.
Vogue Business describes this growing market for unconventional gemstones as a “celebration of individuality.” From ice-blue spinel to soft pink sapphire, Chatham’s palette allows wearers to express personality through colour and choice.
At Lily Arkwright, these rare Chatham gemstones are available for bespoke designs, offering creative freedom alongside ethical reassurance.
