Great Service, All Round

We had my wife's engagement ring valued for insurance purposes. Tim attended a home visit - he had kindly rearranged his schedule on a Friday night for us in order to fit the request of our insurer. He was professional throughout and made the whole experience very easy. He clearly has a passion for the job and I can honestly say it was a pleasure to have him in our home. Would recommend to anyone!

Knowledgeable and Interesting

Tim's valuation process is very thorough and he provides information at every step of the way. His enthusiasm for jewellery is amazing and I felt proud to own the ring he valued. The speed to get an appointment and his turnaround of the detailed report is months better than anything you will find from retailer jewellers.

Very Knowledgeable & Accommodating

We had a Diamond Engagement ring, Diamond Pear shaped solitaire and diamond earrings valued for insurance. Tim from the offset was most accommodating, agreeing to a home visit at 5pm on the 30th December. He spent 2 hours with us that day , taking care to explain to us every step in the process as we were interested, and anecdotally telling us of his past experience. He is a most friendly man, who's knowledge in the subject is both wide and deep. He also brought an enthusiasm to the valuation that I had never seen before in a person so experienced in the job. We arranged to visit him first thing in the morning at his Chelmsford premises a few days later as the valuation had to be finished, and again his knowledge, experience and enthusiasm shone through. The cost of the valuation was very reasonable considering the professionalism and time taken to prepare the report, and the photo's that accompanied the report were first rate. We couldn't have asked for a better service. Thank you Tim.

Watch Valuation

I went to Tim for an insurance watch valuation after finding him online. He was very professional and knowledgeable. The watch was analysed and examined in front of me, several photographs taken. The report was then sent online to me along with the value, it also included all the photos so provides a very comprehensive report. I would recommend Tim's services for any jewellery valuations and the shop was easy to find.

He was knowledgeable and thorough, and very patient answering all my questions as I have never had anything valued before. The report took less than a week and I am so pleased I chose Jewellery Portfolio Valuations. I would recommend Tim and this company to value your valuables!

Highly Recommended

Tim visited my home to appraise a number of items for me and my family. On the day, there were more items than previously agreed with Tim but he was very accommodating, thorough and took time to explain the process and answer any questions. The valuation reports arrived quickly and were presented to a very high standard. Tim took the time to provide each family member with a separate report which was exceptionally helpful. Tim is very personable, professional, and I wouldn't hesitate to recommend him.

I had a few items of jewellery appraised by Tim for Insurance purposes. He was very personable from start to finish and he clearly knew what he was talking about. He valued the jewellery right infront of my eyes which was reassuring since it had centinental value. I will be sure to use him again in the future.

Excellent Service

This was my first valuation and I didn't know what to expect but from the first call with Tim until I received his final valuation, the service I received was exemplary. An appointment was booked within days of my initial contact and Tim arrived on time and with everything he needed. He carried out the appraisals and was very happy to share his knowledge, which I found quite fascinating. A comprehensive report arrived two days later. The whole experience exceeded my expectations.

Another Excellent Valuation by Tim

I used Tim a couple of times in the last year pre-pandemic when he was based in Hatton Garden thankfully I was able to track him down to use him again most recently. He was able to squeeze me in last minute and came to my house and did everything from my dining room table. I had my report later that evening and the hard copy less than two days later. He's super knowledgable and trustworthy, always had a great experience and would recommend him to anybody on the hunt for someone to help them with their valuation needs.
