The Guild of Valuers and Jewellers (GVJ) has launched a claims management service to tackle complicated claims.
The GVJ scheme, which provides discounts for insurers, aims to tackle the problems arising from claims for specialised jewellery. Customers will be given the opportunity to purchase a replacement from the store where they originally bought the item.
It is backed by a nationwide network of jewellers and a database with £350m of valuations which holds records that identify duplicate claims and ensure settlement values are not falsely inflated.
GVJ business development manager Matt Addis said: "It's incredible that some insurers have little option but to accept customers' opinions on the value of their jewellery."
