✦ The Mathematics of Light ✦

Why Round Brilliant Diamonds Sparkle Most

In 1919, physicist and mathematician Marcel Tolkowsky calculated the ideal proportions required for a round diamond to reflect 100% of the light entering through its table back to the viewer's eye. If a diamond is cut too shallow, light leaks out the bottom; if cut too deep, light escapes out the sides, creating a dull center.

At New Origin Diamonds, every round lab grown diamond is faceted according to strict super-ideal angle parameters: Crown Angle of 34.0° – 35.0° and Pavilion Angle of 40.6° – 41.0°. This guarantees three critical optical phenomena: Brilliance (white light return), Fire (rainbow color dispersion), and Scintillation (sparkling flashes as the ring moves).

True Hearts & Arrows

Perfect 360° facet alignment producing 8 symmetrical hearts and 8 sharp arrows.

Triple Excellent Certified

Highest possible IGI and GIA grades for Cut, Polish, and Optical Symmetry.

Frequently Asked Questions

Key guidance for purchasing certified round brilliant lab grown diamonds.

The round brilliant cut is the only diamond shape designed through mathematical optical physics specifically to maximize light reflection. Its 58 facets act as tiny mirrors that bounce light internally and reflect it directly through the crown, creating greater fire, brilliance, and scintillation than any fancy shape.

"Triple Excellent" (or 3X) refers to an official IGI or GIA grading where a round diamond receives the highest grade of **Excellent** in all three cutting categories: **Cut Grade**, **Polish**, and **Symmetry**. This guarantees virtually zero light leakage and optimal sparkle.

Hearts & Arrows describes optical symmetry precision. When viewed through a specialized gemological scope, the diamond reveals a pattern of eight symmetrical hearts through the pavilion and eight crisp arrows through the table. Less than 1% of diamonds worldwide achieve this level of facet harmony.

Direct from our Surat diamond factory, a certified 2 carat round lab grown diamond with Triple Excellent cut and D-F VS quality costs between $750 and $1,100 USD. In US retail stores, the same diamond retails for $3,200 to $4,500 USD, and a mined counterpart costs $18,000+.

A **4-prong setting** allows more light to enter the stone from the sides and can give the diamond a slightly squarish look. A **6-prong setting** accentuates the diamond's round circular contour and provides superior security against accidental impacts, especially recommended for diamonds 1.5 carats and larger.
