Lilia Nash jewellery is made using recycled 18ct gold, white gold, rose gold, Sterling silver and platinum. It's exactly the same quality as mined precious metals but is made using old jewellery, solid gold or silver coins and even recovered gold from electronics like computers and mobile phones! This method of re-purposing gold is environmentally friendlier than mining and treating new gold.
Our gemstones are all purchased from fair trade mines or are lab grown varieties which are also an environmentally friendlier alternative. Full information about the gemstones featuring in Lilia Nash jewellery can be found on the product pages. If you'd like a particular gemstone or fair trade diamond, contact us for more information.
Lilia Nash jewellery is handmade at the Lilia Nash Boutique Shop & Jewellery Studio in Lechlade, Gloucestershire (UK) using traditional jewellery making techniques.
Each piece can be customised to your preference, with the option to make the jewellery in different metals, adapt the details or add a statement gemstone. You can even create a completely bespoke piece of jewellery with Lilia's bespoke jewellery design service.
