We have established the most stringent authentication process in the resale marketplace through years of development and implementation.

• We are dedicated to creating a secure and reputable marketplace for reselling luxury signed jewellery, guaranteeing authenticity. They meticulously inspect hundreds of items each year.
• To ensure the highest level of accuracy and efficiency, we continuously refine our authentication process and internal procedures. Prior to making a purchase, our jewellery experts conduct a detailed examination of every signed piece. This includes thorough checks on dimensions, materials, serial numbers, history, provenance, marks, detail settings, signatures, and more. For special pieces, we also verify their authenticity with the brand store. In addition to our traditional authentication process, we utilize cutting-edge technologies such as AI machine learning.
• We take pride in our commitment to customer satisfaction. If our customers are ever dissatisfied or have any concerns about our products, we are dedicated to resolving any issues and ensuring their satisfaction. Your happiness is our top priority.

We guarantee the authenticity of each signed piece listed in our shop. With every purchase, we provide our clients with a 'Dandelion Antiques Authentic Guarantee Card,' which offers lifelong protection. If, after verification by the brand headquarters' authentication service, it is determined that an item is fake, we will provide a full refund, including the authentication fee, as long as the client can provide proof of the brand headquarters' verification result.

Please Note: We do not accept boutique store sales representatives' opinions, as we have had several experiences where their opinions were proven wrong. The only undisputed result is the authentication result from the brand headquarters

The only indisputable opinion on an item's authenticity is from the brand's authenticity service. This usually means that the piece is sent to the brand's headquarters. The opinion of boutique sales staff, unfortunately, cannot be taken as the final word as they are trained in sales not authentication. This is the reason why the authentication service is in the headquarters only, not in every boutique.

Absolutely. At Dandelion Antiques, each member of our purchasing authentication team has an average of over 7 years of experience working with top luxury jewellery companies and reputable international auction houses in the UK. Over the course of their careers, they have inspected thousands of items, gaining extensive expertise in the field.
