THE EIGHT HEARTS DIAMOND

Shimansky's Exclusive Super Ideal Round Brilliant Cut

When only the most beautiful round diamond will do, the Eight Hearts Diamond stands in a league of its own. More than two decades ago, Shimansky introduced the world-renowned Hearts & Arrows standard to South Africa and, through relentless innovation, perfected it into a world-exclusive diamond, the Eight Hearts Diamond, a super ideal round brilliant cut.

A registered trademark of Shimansky, the Eight Hearts is more than a diamond. It is brilliance you can see with your own eyes and enjoy forever, knowing that you own the best round brilliant diamond you can trust.

WHAT MAKES A ROUND BRILLIANT TRULY BRILLIANT?

The classic Round Brilliant Cut is the most popular diamond shape in the world, designed with 57 facets to maximize fire and sparkle. But here’s the truth: not every round brilliant is equally brilliant.

The difference lies in the quality of the cut, as well as symmetry, alignment, and precision. Many round brilliants are cut to retain weight, keeping more of the rough stone and yielding a higher carat. This compromises brilliance, producing diamonds with less sparkle and lower light return.

The Eight Hearts Diamond is unlike any other. It is cut not for weight, but for ultimate light performance and brilliance. While many round diamonds today are shaped by automated machines for speed and cost efficiency, Shimansky follows a different philosophy.

We combine the latest laser scanning and mapping technology with decades of expertise and human artistry.

Every Eight Hearts is then crafted by hand using traditional diamond cutting and polishing techniques, ensuring that each diamond reaches its full potential and sparkles with unrivaled beauty.

LE SUPER IDÉAL EIGHT HEART™ DIFFÉRENCE

Seuls les Eight Hearts Le diamant est taillé selon les normes rigoureuses de Super Ideal, garantissant une brillance qui dure toute une vie.

  1. Brillance maximale & Feu: Chaque facette est minutieusement alignée par des maîtres artisans pour refléter et réfracter le maximum de lumière possible.
  2. Cœurs & Flèches garanties : Vu à travers une lunette spéciale, chaque diamant à huit cœurs révèle un motif parfait de huit cœurs en dessous et de huit flèches au-dessus, preuve visuelle de la perfection optique.
  3. Structure classique à 57 facettes : Le brillant rond et le Eight Hearts partagent la même structure, mais un seul a perfectionné l'art de l'éclat.
  4. Processus de coupe et de polissage plus long : Un Eight Hearts Il faut trois à quatre fois plus de temps pour tailler et polir un diamant qu'un diamant rond brillant standard.
  5. Le poids est sacrifié pour la brillance : Le poids du diamant brut est plus important, ce qui fait que votre diamant brille davantage et apparaît souvent plus gros que des pierres plus lourdes de taille inférieure.

WHY SACRIFICE WEIGHT FOR LIGHT?

Traditional diamond cutting prioritizes weight gain and speed, retaining more of the original rough to achieve a higher carat number, especially when aiming for a higher weight category, which is worth a higher price per carat within that category.

  • The Eight Hearts philosophy is different.
  • More rough material is sacrificed.
  • The result is a diamond that may weigh less but outshines heavier stones.
  • This sacrifice guarantees maximum sparkle, fire, and brilliance that lasts forever.
  • Less rough weight. More brilliance
