The effect.
The signature Montluc sparkle.

A minimum of 170 and up to 195 top-grade diamonds are meticulously set the entire way around this unique signature piece, recreating the glitter of a night sky in a band of sculpted 18k gold. The attention, the compliments, the flattery… they simply can’t hide what people really feel. You’ll just have to get used to the envy.

The design.
Man and machine in perfectly precise harmony.

Designed by human creativity, yet crafted with a precision beyond the reach of the human hand. Only our industry-leading robotic technology can achieve the accuracy required to set this many different sized diamonds with this breathtaking level of detail. Separated by an average distance of just 0.12 millimetres, each and every diamond is fixed with a minimum of four individual prongs. Looking for a talking point at that dinner party? You’ve just found at least 170 of them.

The diamonds.
It’s all in the cut.

If you’re looking for that ‘Oh wow, I can’t believe how much it sparkles’ factor, it’s all about the cut. The vast majority of diamonds are graded from Poor to Excellent as per official GIA (Gemological Institute of America) cut grades. Montluc, by contrast, only ever uses a standard that goes one step further. Two, actually. Our Triple Excellent cut perfectly balances the reflection of light to create the signature Montluc sparkle.

The quality.
Exeptional. No exceptions.

Montluc works with only the very best diamonds in the world – and needless to say the quality of our gold is equally uncompromising. The Jealousy is sculpted from a solid 18k pd135 gold bar, a highly exclusive gold containing 13.5% palladium. On the highly unlikely occasion you find a similar diamond ring of equal quality at a more attractive price, we strongly advise that you buy it. Immediately.

The guarantee. We don’t compare to the very best. We are the benchmark for it.
