I sent off a couple of diamond rings and bracelet to be sold and was amazed at the service i received. Within two hours of receiving the items, Philip had given me a price which i was entirely happy with and the funds were transferred to my bank account. Should i ever wish to sell anything like this again, he will be my first choice! Thanks for such an amazing and stressfree transaction!

I felt apprehensive about this whole process! Celsteel provided an excellent service, with thorough explanations. I felt no pressure, and reassured. Super quick service, same day payment. I will definitely use Celsteel again - Thank you

We had a friendly greeting followed by having all details explained in selling a diamond. Each step was shown about our diamond clarity,weight etc. After all put together a price was offered, we were given time to decide or go away and think about it even go somewhere else to see if we could get a better price. The offer was close to what we already knew, agreed sale payment received. Left feeling relaxed over whole experience.

I sent my engagement ring off on Friday, after already having an initial valuation. The service I received was second to none. I was kept up to date with what I needed to do to send the ring to London, I was emailed when the ring was received and confirmation of the quote. I simply then had to sign a declaration and send my bank details and the money was in my account the very same day. I found this to be an excellent service to sell unwanted jewellery and I would not hesitate in using them again. First Class.

A very professional and personable service. Was offered a very good valuation and agreed immediately. Now I know Phillip will always give me the best price I will always use him.

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.
