GRUNBERGER PRECISION CUT®

Our Grunberger Precision Cut® has ideal proportions for melee and boasts the most brilliance and best light performance. Due to our superior optical symmetry, our diamonds feature the faceted pattern known as Hearts & Arrows. We follow the highest level of grading stand- ards and business ethics through the guidelines of AGS 0.

The Grunberger Precision Cut® was created with the desireto bring out the best in what a diamond has to offer.

4C OF A DIAMOND

The 4Cs have since become the standard for describing a diamond’s specific characteristics. The combination of Cut, Colour, Clarity and Carat denote a diamond’s value and rarity.

The diamonds at Grunberger are of the highest quality within the 4C criteria.

HEARTS & ARROWS

Grunberger Precision Cut® diamonds are known for the consistent and perfect Hearts & Arrows pattern. When viewed through the Hearts & Arrows scope, 8 hearts are visible when viewed from the pavillion and 8 arrows are visible when viewed from the table. The Hearts and Arrows pattern allows our diamonds to bring unparallel- ed fire and brilliance to your jewelry.
