CRAFTSMANSHIP

Craftsmanship behind every cut

Every grown diamond cut by our master craftsmen dazzles. Every facet speaks of their skill and experience. Light plays with every angle perfectly, turning it into a ball of fire. Rough diamonds brought to life by master craftsmen committed to a single goal: to realize perfection in every lab diamond.

Diamond cutting

An art and craft

Watch how rough diamonds are brought to life by our master craftermen.

01.

Hearts

When the lab diamond is viewed from the bottom (pavilion), it should reveal eight symmetrical hearts.

02.

Arrows

When viewed from the top (crown), an ideally cut diamond should reveal eight symmetrical arrows

03.

AGS 000

The AGS 000 designation represents diamond cutting excellence - a grade achieved when a diamond attains the highest possible rating across three critical parameters: proportions, polish, and symmetry, each assessed at the ideal level of zero. Verified with the AGS Angular Spectrum Evaluation Tool, evaluating the interplay of brightness, contrast, and light retention, ensuring that only diamonds of truly superlative character receive this most distinguished classification.

Exceptional Diamonds. Verified Excellence

Certifications

We are the largest manufacturers of GCAL 8X certified lab diamonds.

CERTIFICATIONS
GCAL 8X - the apex of gemological certification and assurance

GCAL is the ultimate diamond precision standard, reserved for less than 1% of all diamonds. Our diamonds are graded by GCAL, evaluating 8 distinct parameters of diamond perfection—a standard that goes beyond the conventional 4Cs grading. Only exceptional diamonds achieve distinction across all eight criteria, marking them as truly extraordinary.

FAQs

Master Cut diamonds are precision-cut by GDC's master craftsmen to achieve Hearts and Arrows symmetry, AGS 000 proportions, and GCAL 8X verified optical performance across all eight grading parameters.

When a round brilliant diamond is viewed from the pavilion, it reveals eight symmetrical hearts. From the crown, it reveals eight symmetrical arrows. Both patterns confirm precise optical alignment in every facet.

AGS 000 is the highest possible cut grade, awarded when a diamond achieves ideal ratings across proportions, polish, and symmetry. It is verified using the AGS Angular Spectrum Evaluation Tool for light performance.

GCAL 8X evaluates polish, external symmetry, proportions, optical brilliance, fire, scintillation, optical symmetry, and hearts and arrows pattern. Only diamonds meeting the highest standard across all eight parameters qualify.

Fewer than 1% of all diamonds qualify for GCAL 8X certification. GDC is the largest manufacturer of GCAL 8X certified lab-grown diamonds in the world.

A standard Excellent cut grade evaluates proportions on paper. Master Cut diamonds are verified for actual optical performance using GCAL 8X scanning technology, measuring real light behavior across all eight parameters.
