About Us

Tim is a fourth generation jeweller originally from Kettering where his great grandfather, Arthur Augustus Thornton began trading as A A Thornton in 1911. He was an apprentice watchmaker in Birmingham's Jewellery Quarter, and his watch repair skills were the base of his new business. He was then succeeded by his son Pat and Tim's father, Simon until his death in 1997.

Tim entered the jewellery trade in 1989 at the family business in Kettering. Passionate and eager to learn, he soon completed his Retail Jewellers Diploma, and became a qualified Gemologist and Diamond Grader, skills which helped on buying trips to Sri Lanka to source many usual and unusual gemstones. 

In 1995 Tim took the chance to work for Christies in South Kensington as an antique jewellery specialist, staying for two years until returning to Northamptonshire in 1997 after his father's death.

Tim has since worked as a valuer in both the UK and New Zealand, and was Department Head and auctioneer for a leading Birmingham auction house for 2 years.

Tim now lives in Market Harborough with his wife and family, and is an active member of the local community. With over 25 years experience, Tim's passion for the jewellery business is undimmed, and he proudly offers a very high level of service to all his customers. Tradition and Style are the watchwords at the 3 Coventry Road store which sum up the jewel in Market Harborough's crown perfectly.

Tim has made many radio and TV appearances and has been a speaker on his specialist subject of antique jewellery at fundraisers for many local organisations.

    Dear Tim

    I want to thank you for organising the repair and replacement diamond to my engagement ring, and for your help liasing with the insurance company. I couldn't be more pleased with it, restored to its beautiful 1930s good looks.

    Many many thanks.

    “We have used the jewellers on Coventry Road for many years, but didn’t realise it had been taken over by Tim until we went in to buy a new wedding ring for myself as I had lost mine on the beach in Ireland this summer! Tim was most helpful and we soon came to a decision, and because the ring that I lost had great sentimental value to me, I had the inside of the band engraved. The bill wasn’t as much as I was expecting and the quality and craftsmanship of my ring are second to none.”

    “I have recently used TJ Thornton for a watch repair and purchased a gold bracelet. On both occasions I received the very best service from Tim Thornton, nothing was too much trouble. A very traditional jeweller, selling quality items. I am only too happy to recommend him. I shall certainly be using his shop in the future.”

    “A fantastic experience in comparison to other similar businesses in MH. Tim is a very helpful honest chap, and if he can help you he will! This was my first visit today but won’t be my last! Thanks for great service.”

    “Tim helped me source some items very quickly and efficiently. The cost of the items represented very good value and delivered with professionalism and a smile. I would recommend Tim and wish him every success.”

    “I bought an engagement ring from TJ Thornton, after looking in several other jewellers. The reason we chose to buy from Tim was that the shop seemed much more individual in its approach to the customers than others we visited. Tim was very knowledgeable, informative and helpful, and customised a beautiful ring for us. The whole thing felt much more special than buying something off the shelf. He kept us informed throughout, and was able to have the ring ready when we wanted it despite the relatively tight deadline. Because of the excellent service and good value, we fully intend to buy our wedding rings from TJ Thornton as well!”
