What is Assay Assured Moissanite & UK Hallmarked Jewellery?

All our moissanite jewellery is UK hallmarked and carrys our Assay Assured trustmarked certification here in the UK. But what does that really mean? 

The Assay Assured Trustmark

Assay Assured is an organisation that monitors online jewellery retailers. They provide the Assay Assured trustmark to online jewellery stores that pass their rigorous assurance checks and frequent auditing. When you find an online jewellery store that’s Assay Assured, it means they’ve passed the following tests:

  • Company audits and verification checks to prove their authenticity.
  • Quality checks to test their jewellery items and the core materials.
  • Random auditing checks on products that can happen at any time.

In the unlikely event any issue should arise regarding the quality of our products or services, you, the customer can raise this direct to Assay Assured and they will act as an independent arbitrator providing the ultimate piece of mind.

Once a retailer is Assay Assured they’re awarded a certificate and a hallmark image to certify their website and products. You can see our trustmark on our homepage or click here.
