Yes, please bring your items to our showroom – prices can only be discussed upon inspection of the gem material you are selling. The best time to come in for this is before 11.30am or after 3pm, Monday to Friday. What kind of stones are you looking for?

Yes, we can value jewellery and gemstones for insurance purposes for which we will produce a certificate of insurance replacement value. At Holts we have been dealing with stones and jewellery for over seventy years. The experience and knowledge we have acquired over this time is available to you in our valuation and gem testing service. Our on-site service will provide you with detailed identification of the jewellery pieces with their descriptions and values for the purpose of insurance valuations. Our insurance valuation service starts from £80+ VAT, but depends on the individual item (average price £120 + VAT). There is no need to book an appointment. We only perform valuations during the week (Monday – Friday). We require at least 24 hours to perform a valuation although we may be able to offer a same day turnaround depending on workload. When left with us, you will be given a full record and receipt of the items in our care. This includes a photocopy and receipt of all items . We pride ourselves in being thorough and all valuations will contain photographs of the item(s), estimated weights (or specified where certificates are supplied) and colour stones will be tested and verified in our laboratory. Your items will be kept on our premises at all times and be insured whilst in our care. We kindly ask that you bring along any documentation associated with the piece to be valued.

We do provide testing services for which we issue a Test Certificate.

The fee for this service starts from £40 + VAT.

Certificates do not state pound values, but will state the species and variety of the gem material and in some cases comment on any treatments performed. We do not issue reports regarding the geographical origin of gemstones.
