Who we are and what we do
We are a well established company with a proven track record trading from safe and secure premises.
We are a business run and managed by professional diamond graders.
We have a no nonsense approach to making offers. Payment is immediate; funds are cleared in your account before you leave the office or made in cash*.
Your jewellery never leaves your sight during the whole process.
*For jewellery up to the value of £5,000. Amounts over this amount will be made by direct transfer.
Who we are not and what we won’t do
We are not a business without a physical address which you can’t visit.
We are not a business with only a mobile phone number.
We will not pay you by cheque (unless specifically requested) or offer to sell on your behalf and then pay.
The founder, Daniel Rosen, is a member of The London Diamond Bourse and World Federation of Diamond Bourses, and has been since 2000. He is a graduate from The Institute for Diamond Studies and has more than 25 years’ experience in the industry as a diamond cutter, sorter, selector, instructor and dealer. His knowledge and understanding of diamonds from the rough to the polished is testament to the achievement of 14 years of sustained growth and, together with a dedicated team of experts, 4Cs Diamonds is set to continue this trend for many years to come!
The Diamond Industry is notoriously built on trust, and it is trust which you, the seller, must have when offering your precious stones for sale to a dealer. 4Cs Diamonds trades from secure and safe premises in a dedicated jewellery suite at 100 Hatton Garden.
