About BrilliantC®
BrilliantC® is created for individuals in search for the ultimate diamond jewellery that leaves an indelible impression, and a remarkable legacy.

While many diamonds in the market are cut to retain weight or even to an Excellent grade, BrilliantC® goes a few steps further.

The BrilliantC® Diamond is cut according to an exclusive mathematical formula of proportions and angles (patent pending), innovated by DeGem, a top regional jeweller with over 40 years of experience.

Flawless Light Performance

The goal? To deliver flawless light performance — maximising fire, brilliance and scintillation, evident to the naked eye, and quantified by advanced scientific graded technology.

When light reflection and refraction in a diamond is maximised to this level, it results in the diamond appearing much whiter than its natural colour grade.

BrilliantC®'s light performance is also verified with the following scientific measures:

AGS Ideal 0000

BrilliantC® utilizes American Gem Society Laboratories' (AGS) patented ray tracing test, to analyse how light actually travels within each BrilliantC® diamond.

Each BrilliantC® Diamond scores an AGS Ideal 0000 — first-class grades in the four criteria of Cut Grade, Light Performance, Polish and Symmetry — a novel measure not yet widely adopted by the jeweller industry, reserved for truly exceptional diamonds.

Less than 0.1% of world's diamonds meet this mark of excellence.

Transparent and Traceable Origins

For the environmentally conscious client, you can opt for stones that have a BrilliantC® Diamond Time-Lapse traceability report – a digital report documenting the entire journey of your rare diamond—from the origins of its rough, to how it was masterfully planned, cut and polished, and finally expertly set into signature BrilliantC® designs for you.

In this exclusive report, every moment of cutting your BrilliantC® diamond is visually documented, due to our partnership with a global diamond cutter to wholly source conflict-free rough to cut BrilliantC® diamonds consistently, and transparently showcase the beauty of your diamond's architectural process.

BrilliantC® is the world’s first ideal cut diamond with transparent and traceable origins.
