What is a Parti Sapphire?
Parti sapphires are a rare and completely natural mineral with a mix of two-three colours in the same stone, mainly blues, greens and yellows. These colours emulate the iridescence of peacock feathers and make for a very unusual engagement ring or an eye-catching piece of occasion jewellery.

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.

Customise This Ring
Lilia Nash's signature ring designs can now be customised! Design your ring with any of the available gemstones, or Lilia can source a special gem especially! Choose between 18ct white gold, rose gold, yellow gold or platinum and pick your favourite finish. All of our custom rings can be ordered in UK, US or EU ring sizes, including plus sizes.

Your ring can be resized for FREE by up to 3 sizes smaller or 3 sizes larger.
To ensure you buy the exact ring size you need, we recommend using our ring sizer loan service. If you're planning a proposal or want to buy a Lilia Nash ring as a surprise gift, it's possible to resize your ring in the event that it doesn't fit!
Find out more about our FREE ring resizing service here.
Please note, we can't resize rings that have been engraved. If you'd like your ring/s engraved but you're not 100% sure on the sizing, we recommend you send it to us for engraving once you're happy with the fit.
