As an Assay Assured retailer we can guarantee that we exceed all legal standards of assaying and hallmarking our precious metal jewellery, to provide our customers with the confidence that all our pieces have been audited and tested to provide the highest quality jewellery, true to description, so you can trust that you will receive genuine branded products when buying from us.

Assay Assured have been testing and hallmarking precious metals for over 550 years. The Assay Assured trust mark is the only trust mark specifically for online jewellery retailers, enabling consumers to reduce their risks of encountering counterfeit and fake jewellery when buying online and allowing high quality online jewellers, such as ourselves, to promote our good practice.

Assaying is the independent testing of the fineness, also known as purity, of precious metals used for jewellery. When creating fine jewellery precious metals are rarely used in their purest form and instead are alloyed with other metals to create a stronger, workable, yet just as beautiful material suitable for use on fine jewellery. As it's impossible to determine the precious metal content with the naked eye, even experts can't determine metal standards without specialist equipment, assaying is necessary to prove precious metal content in fine jewellery. This involves weighing the metal alloy and recording the precious metal content in parts per thousand. For example, as standard at Lily Arkwright we stock 18 karat gold which equals 750 parts per thousand.

As an Assay Assured retailer all of our jewellery is hallmarked to verify the purity of the precious metal content. Each hallmark includes the sponsor mark, representing who made the piece, the fineness mark, showing precious metal content and the assay office mark, indicating where and when it was made.

The UK is one of the only countries to have statutory hallmarking, which states that by law jewellery cannot be described as being gold, silver or platinum without hallmarking. Independent, third-party Assay Offices are responsible for testing and hallmarking every piece of precious metal jewellery as required by the Hallmarking Act, which, dating back to the 1300's, is one of the oldest forms of consumer protection. We are registered with the Sheffield Assay Office, a centre of expert opinion with more than 245 years of experience, providing our customers with the reassurance that each and every Lily Arkwright design has been carefully tested to ensure the highest quality available and compliant with UK regulations, as supported by our status as an Assay Assured Jewellery Retailer.

We pride ourselves on our ability to produce stunning ethical and sustainable fine jewellery at an amazing price point, supported by unrivalled customer service. We offer the highest quality moissanite engagement rings, lab grown diamond engagement rings and coloured gemstones.
