Have your diamond jewellery professionally assessed

The value of diamond jewellery depends on factors such as the precious metal, design, finish, brand, condition and characteristics of the set diamonds. We therefore assess the complete piece in person and without obligation.

This service is exclusively for complete jewellery with set diamonds. We do not purchase loose gemstones offered separately.

Expert assessment of diamond jewellery

Our GIA-trained expert assesses the diamonds as part of the complete piece. We also examine the precious metal, setting, finish, any brand marks and the overall condition. You receive a clear explanation before you decide.

Documentation

Certificates and purchase documents are welcome

Do you have a certificate, purchase invoice, brand document or original packaging for the jewellery? Bring it with you. Documentation can provide useful additional information, but the assessment remains based on the complete piece you present.

Information

What determines the value of diamond jewellery?

Value is not determined by a single characteristic. We consider factors such as the type and weight of the precious metal, quality of the setting, design, brand, signs of wear and market demand for comparable jewellery.

The set diamonds are assessed as far as possible without damaging the jewellery. We consider visible size, cut shape, colour, clarity, number and placement. You then receive a transparent, no-obligation offer for the complete piece.
