THE ART OF LIGHT: MORE LIGHT. MORE FIRE. MORE BRILLIANCE.
Every Brilliant 10 Diamond is cut to mathematical perfection, achieving brilliance, fire, and scintillation beyond even the highest gem standards. Unlike the traditional 57-facet round brilliant, its unique 71-facet design ensures that light entering the diamond is reflected directly back to the eye revealing extraordinary sparkle from every angle.
Where many round brilliants are cut to retain weight rather than optimise light, the Brilliant 10 is cut for light, not for size. Each facet is precisely proportioned to unlock the diamond’s full potential, producing an intensity of brilliance few can match.
Building on the legacy of the Eight Heart™ Diamond, the Brilliant 10™ marks a new chapter in Shimansky innovation.
Featuring ten perfectly symmetrical hearts and ten precisely aligned arrows, it represents the ultimate balance between science and art crafted by master cutters who combine advanced laser technology with decades of expertise and hand-polishing precision.
PRECISION IN EVERY FACET TEN HEARTS. TEN ARROWS. INFINITE BEAUTY.
Using advanced optical symmetry technology, each Brilliant 10 Diamond is polished with unrivalled precision.
Viewed through the Shimansky Hearts & Arrows viewer, the perfect pattern of ten hearts and ten arrows reveals a harmony achieved only through human craftsmanship guided by science. It is this balance of proportion and symmetry that creates the diamond’s unmatched sparkle.
Only the world’s most skilled master cutters can achieve the flawless symmetry required to earn the title Brilliant 10.
Each diamond undergoes meticulous evaluation by Shimansky’s in-house experts to ensure it meets the strictest standards of brilliance and proportion. Its rarity lies not only in nature, but in the mastery of its creation.
WHAT MAKES A BRILLIANT 10 DIAMOND SO BRILLIANT
FACET COUNT
71 facets, engineered for light return. The Brilliant 10 uses a patented 71-facet design (vs the traditional 57) to maximise light performance.
SYMMETRY STANDARDS
Brilliant 10 is cut to optical perfection, revealing a precise 10-hearts/10-arrows pattern — proof of extreme symmetry and proportion.
VISIBLE HEARTS & ARROWS
Verified under an Ideal Scope. View from the Top to see 10 arrows; from the Bottom to see 10 hearts, a clear visual signature of the Brilliant 10 cut.
BRILLIANCE & FIRE
8% More light returned to the eye. The Brilliant 10 displays up to 25% more brilliance and appear up to two shades whiter than its colour grade due to its facet architecture and symmetry.
CUTTING TIME
Significantly longer than standard cuts. Achieving the 10-hearts/10-arrows precision requires extended mapping, cutting and polishing by master cutters, prioritising perfection over speed.
ROUGH WEIGHT RETENTION
Cut for light, not for weight. More of the rough is sacrificed to reach the Brilliant 10’s strict proportions and symmetry, elevating light return over carat retention.
EXCLUSIVITY
Patented & exclusive to Shimansky. The Brilliant 10 is a Shimansky-designed, patented round brilliant cut available exclusively from Shimansky.
If You Love The Classic Round Brilliant Diamond Cut. Why Not Choose The Best Version?
WHY SACRIFICE WEIGHT FOR LIGHT? LESS ROUGH WEIGHT. MORE BRILLIANCE. MORE LIGHT.
Traditional diamond cutting often values weight over beauty, keeping more of the rough to reach a higher carat category and quicker finish.
The Brilliant 10™ philosophy is different.
Shimansky master cutters sacrifice more of the rough to achieve perfect symmetry and the 71-facet, ten-hearts and ten-arrows design.
The result?
A diamond that may weigh less — but shines with up to 25% more brilliance, radiating fire and light from every angle.
YOUR BUYING GUIDE TO THE MOST BRILLIANT DIAMOND IN THE WORLD
When buying an engagement ring diamond, brilliance is the detail that matters most. Here’s what to look for with a Brilliant 10™ Diamond:
