Highly Professional

Tim helped me with the purchase of a pre-owned diamond ring by providing an assessment and valuation. He was highly professional, friendly and flexible to the challenge of organising the task. A great service which increased my confidence to buy the jewellery. I would not hesitate to recommend him to others.

Excellent Watch Valuation

I recently instructed Tim Bicknell to undertake a valuation of my watch for insurance purposes, and the entire service provided was excellent from start to finish.

Very clear communication by email and phone, complete clarity on the process and an excellent price. Tim visited me at home and completed all the required steps very quickly and was an absolute pleasure to deal with. He demonstrated detailed expertise and huge amounts of knowledge, which was greatly appreciated. I had my valuation back very quickly, helping me to sort out all of my arrangements.

Expertise / Items Examined: Rolex watch.

Excellent Service

Tim provided a brilliant same day service for me when I walked into the jewellers in Chelmsford High Street. Tim was very friendly and took the time to answer all my questions fully in a professional manner. Tim was able to provide me with a valuation within a couple of hours so that I was able to take the rings home with me that day, and provided the full valuation report including photos later that night. I would definitely recommend Tim to anyone looking for a valuation - a great service and I will definitely return in the future!

Expertise / Items Examined: Engagement and Wedding Ring.

An Excellent Service

Whilst undertaking the valuation of a gents ring, Tim's professionalism, friendly manner and knowledge shone through; happily explaining the process and answering any questions I had before providing a quick valuation on 3 bracelets. The final paperwork was completed in a couple of days and was accompanied with an excellent Valuation Portfolio. An excellent service.
