Gemstone Necklaces
A Passion for Gemstones
Gemstones have been a lifelong passion for David. His dedication led him to study at the internationally recognised Gem-A, where he achieved the prestigious DGA accreditation. We offer a carefully curated selection of diamonds, sapphires, rubies, and emeralds-and are always delighted to guide you through the choices. David explains both the technical and aesthetic aspects in a relaxed, approachable way, ensuring you feel informed and inspired.
David Ashton Necklaces
Our pendants are designed to remain fixed in place on the chain. This ensures the clasp stays neatly at the back while the gemstone rests perfectly at the front. Each David Ashton necklace can also be tailored to complement your ring or earrings, creating a beautifully balanced and bespoke jewellery set.
Sustainability at the Core
Sustainability is at the heart of everything we do. All David Ashton diamonds and gemstones are 100% conflict-free, sourced and certified to the highest standards. Our bullion is 100% recycled and responsibly sourced under the LBMA Responsible Gold Sourcing Assurance-so you can wear every piece with confidence, knowing its integrity matches its beauty.
