About Brillian


Brillian is an online jewellery business selling the best quality diamonds and custom-made jewellery throughout the UK and abroad.

Based in the heart of London's famous jewellery district, Hatton Garden, Brillian have built an excellent reputation over many, many years as experts in sourcing beautiful diamonds and producing fine diamond jewellery.

At Brillian we understand that buying a diamond is an important investment, which is why we use our 50 years collective experience in the diamond industry to ensure you receive the very best clarity, cut, colour and carat of diamond for your money. It is for this reason and because we have such low overheads that we can supply the most beautiful, certified diamonds at a fraction of the cost you would have to pay at high street retailers.

You can either shop safely and securely online or you can browse our store and then call us to arrange an appointment with one of our sales managers in our exclusive luxury Hatton Garden showroom.

We are also able to produce jewellery that has been designed by you - just get in touch and our craftsmen will produce a unique and beautiful handmade piece for you.

All our products are fully insured and delivered by Royal Mail Special Delivery, with guaranteed delivery before 1pm the following day.

Remember, Brillian have a wide choice of diamonds and jewellery in stock, so if you are looking for something in particular or you would like to discuss your requirements in more detail then please get in touch.
