Phil was excellent to deal with and Celsteel is a highly professional company – one of the best in London. Highly recommend anyone looking to buy or sell diamonds.


14th April 2021

Fast, easy service with good communication. I didn’t get the price I wanted but pleased with ease and speed.


1st March 2021

I had a great experience with Celsteel. I sent an enquiry giving them the specs of my diamond, they gave me a valuation for it, I dropped it off for them to check that everything was OK and within the hour they had deposited the funds into my account. I would definitely use them again.


18th February 2021

I cannot fault the service when selling my ring in the slightest. My initial enquiry and additional questions were dealt with quickly and efficiently, and the payment was made equally as fast too.
Phillip was very polite and and I was happy overall.


11th December 2020

Having never sold a piece of expensive jewellery I was particularly wary of sending this item to a buyer by post. Phillip and Celsteel made the whole process and seamless and and easy process: from the initial valuation to detailing how to send it by post, to quick correspondence throughout to receiving the funds on the same day the item was received, I would have no hesitation in highly recommending the Celsteel and using the company in the future. Thanks for all your help!


3rd December 2020

Phillip was extremely helpful with the whole process from start to finish. I was very Happy with the offer made and funds where received on the same day as the valuation. If you do have any jewellery you are considering to sell, I would highly recommend Celsteel. Very very professional service


1st December 2020

Excellent communication and clear instructions put my mind at ease. The transfer was quick with no hassle and initial quote was honoured. Would definitely recommend.


6th October 2020

A very professional organisation, who clearly demonstrated very high standards of customer service. This is a organisation you can trust, and expect a fair valuation.


2nd October 2020

Thanks a lot for your very efficient and friendly service. If the occasion arises at some time in the future I shall certainly have no hesitation in recommending your firm.
Although the deal was struck at a distance, on line, I felt safe and confident dealing with Phillip who seemed to do all that he could to ensure that I was comfortable working in that way.

I was initially very worried about posting my diamond ring as I live outside of London, however after speaking to Phillip and reading previous reviews I felt more confident. Phillip e mailed to let me know it had arrived and throughout the whole process his communication was excellent! I will definitely be recommending celsteel! If you are concerned in anyway then don’t be, know that your jewellery is in safe hands. The money was in my account instantly. Thank you very much Phillip.


11th September 2020

Excellent communication, I had a reply almost instantly even when I messaged at 6.40am.. Everything was done by email because I live outside London but at no time was I left concerned.


8th September 2020

Phillip was excellent at communicating the price and the process for my jewellery. Payment was super fast and the process was very very easy. I would wholeheartedly recommend their services.


10th August 2020

Great service, and a great selling experience. I did a lot of research to find the best price for my diamond, and this was absolutely it. The process was completely secure and safe, and I would definitely recommend. Thank you so much.

2nd March 2020

Great service. Practical and down to earth


28th February 2020

The most professional service I received in Hatton Gardens by far. Philip is highly professional. The whole process of selling was very straightforward and completely transparent. It was a far more pleasant environment than visiting shops. Philip provided a personal service and we dealt with him from start to finish. I can’t fault the service, nor Philip.


17th January 2020

Amazing service. Engaging and informative buyer who understands his profession. A good experience and result for me.


26th November 2019

Philllip and his daughter were utterly professional, polite and efficient, so the whole process was smooth and stress free. I was offered a price I was happy with, everything was clearly explained and the entire transaction was processed in a competent and warm manner. I felt confident that the sometimes daunting process (to a relative novice) of selling a diamond was being very well conducted. I would definitely buy and sell with Celsteel again and have no hesitation recommending them to others.


29th October 2019

The service from Phillip has been extremely professional and efficient. He explained the process in detail and provided me with the confidence to agree to price offered. I have no hesitation whatsoever in recommending Phillip and Cesteel for anyone wishing to sell their valuable jewelry.

Having recently used the services of Cesteel I was very impressed with how straight forward it was. The process was extremely quick and efficient. The full process took a matter of days.


5th September 2019

I met with Phillip to get a valuation of my engagement ring. He was courteous, honest and put me at ease. I was a little nervous about the process as I hadn’t sold a ring before. He made the whole process a pleasure and I left with an amount that I was happy with. Phillip was easy to talk with and I felt relaxed and would highly recommend him to my friends and family if they want to buy or sell diamonds. , He had a professional and warm presence and was knowledgeable and transparent throughout the whole process.


6th August 2019

I called in to see Phillip hoping to get a good price for an unwanted ring.

Over the years I have dealt with a lot of jewelers in different countries but to be honest none have been as helpful and as straightforward as Phillip was when we met.
He thoroughly cleaned the stone before valuing it. Within 20 minutes we had agreed a price and the money was transferred in to my bank account before I left his office.

If you are looking to buy a stone then a visit to Celsteel Diamond is a must. Apart from being looked after really well you will be in a very safe environment in their office.

I have friends in many countries and everyone will be told where to go if they want to buy a stone.

Gave me a reasonable price on an unwanted engagement ring. Danielle was great to deal with and cash was paid into my account within minutes. A hassle free transaction, would recommend to anyone with high quality diamonds to sell.


18th June 2019

I had gone to Celsteel to get a second opinion and was offered an exceptional price for my ring ! Within minutes I had also received a payment. A family run business for generations that go that extra mile for each client. No need to go elsewhere Celsteel will look after you! Thank You


12th June 2019

It was a pleasure to find such professional, efficient and kind people. I would use their service again, very happy with the experience!

Offered by far the best price for my diamond, excellent customer service and quick payment. Highly recommended.

AS-Abu Dhabi

11th February 2019

Very easy and comfortable process, Phillip was quick to respond to emails and upon taking the ring to his office, he gave us a fair and honest price which we accepted and was paid in cash there and then. Having looked at a couple of other options Celsteel was the one that we felt most comfortable in selling to. A trust worthy family business who I wouldn’t hesitate to use again or recommend. Thank you


5th February 2019

Phillip was super quick to respond to all emails and the whole process was done within 24hrs. The first offer made was the one he stood by upon recieving the ring. I expected Phillip to try and make a lower offer upon recieving the ring, however he was true to his word! Payment made the same day. All in all a very good experience and I would recommend him to others!

Friendly and straight forward service.


15th November 2018

Very quick service, always replied to emails promptly, gave a good estimate. Sent the ring and as soon as it was received I was given a definate price, the money was then sent to my bank as soon as I had completed the paperwork. Very quick reliable service.


13th November 2018

I was so pleased with the service given. I was advised to send by special delivery and have my items insured. My parcel arrived the next day as expected. I was very quickly informed and given an offer for my diamonds that very day.
The process was so quick and easy. The money was in my account as soon as I’d completed the acceptance and declaration form again on the day of them receiving them.
Highly recommended company. I trust them and would 100% use them again.


13th November 2018

An amazing service with Celsteel! I started trying to get the best offer for two diamond rings on a Wednesday. The best offer was by far from Celsteel. I sent rings off to Phillip Chib (Director) that day, I had a confirmed offer Thursday morning which I accepted. I emailed my signed declaration form Friday morning (around 7.30am) Phillip responded immediately (probably over his breakfast, in his own time) to let me know that when he got in to the office he would transfer monies. Money was in my account that morning. A very friendly and superb service received and a very happy customer 😊

A very professional and speedy service. Highly recommended.


29th October 2018

It was refreshing to find someone who is honest and upfront with the process of buying my diamond rings. From start to finish he never pestered me like other jewellers did with low valuations. It was lovely to meet him and his family. We would use him again without hesitation and recommend him to anyone.

16th October 2018

From the first time I contacted Philip via email, his responses were prompt, polite, professional and clear – both on email and in person. He was honest and upfront without wasting my time, allowing me to make an informed decision to sell my diamond ring. The process was straightforward and I would absolutely use Celsteel in the future.


1st October 2018

I have visited Phillip at Celsteel on a couple of occasions for valuations and to sell diamonds.
He provides expert knowledge and honest advice and offers fairer prices compated to other dealers in Hatton Garden.
I always visit Phillip first when in Hatton Garden as my experience is that other dealers never match his buying prices.


25th September 2018

Great service by Phillip very quick responses to emails paid me a good price would use him again.

I would recommend this friendly and professional family business. Really prompt and clear communication. The quote was accurate when it came to seeing the ring in person. Prices seem standard for this industry. Would happily use again.

I experienced very good communication and a very prompt and fast service. I would highly recommend using this company. Phillip was very clear in what I needed to do and was always at the end of an email.


27th April 2018

Great buyer after being insulted by everyone else i visited Celsteel diamonds Philip took his time to view my stones then made me a very impressive offer that was way in front of all the jewellers and other diamond dealers i had visited, Highly recommended


15th January 2018

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.


9th January 2018

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.


18th December 2017

Very nice. Good price, same day payment

13th October 2017

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.

Very easy transaction . No hassle


27th September 2017

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.


21st September 2017

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.
