Producing Jewellery With The Highest Quality Diamonds

Brillian

The beauty of purchasing a diamond engagement ring, necklace or earrings from Brillian is that you can take advantage of our low prices but still receive a product that is of the highest quality.

We want you to be happy with your piece of jewellery which is why we encourage you to book an appointment with one of our experienced sales managers in our luxury Hatton Garden showroom.

You can also be reassured that every single diamond we sell has been carefully graded by one of four internationally renowned gemological institutes: Gemmological Institute of America (GIA), International Gemological Institute (IGI), HRD Antwerp and the Antwerp Gemological Institute (AGI).

When you receive your diamond engagement ring it will be accompanied with a certificate from one of these institutes that states the size, clarity and cut of the diamond.

At Brillian we maintain the very highest ethical standards and are fully committed to the Kimberly Process which states that we never buy, sell or handle conflict diamonds. If you would like more information about you can find out more here.
