I thought that the way in which Phillip conducted the sale of my jewellery was highly professional and I will definitely go back to Phillip in the future with any other items I wish to sell. A very good company and I would highly recommend Celsteel.

A thoroughly brilliant, professional, courteous and honest service provided by Phillip and his team at Celsteel when it came to selling my diamond ring. I had no idea what offers to expect when going to Hatton Garden and meeting with several dealers there last week - but Celsteel were simply THE BEST and offered me a fair price and immediate payment. Phillip was also kind enough to provide me with a free valuation letter for another item of jewellery that I showed him. An excellent company to deal with and highly recommended.

I have held on to my rings for over 5 years. Not been able to find a trustworthy person to sell my rings too. Phillip was wonderful, made the process so easy. Within 24 hours the deal was done. Highly recommend to anyone looking to sell their jewellery.
