FOR IMMEDIATE RELEASE

Grown Diamond Corporation today announced the launch of its D–Flawless / GCAL 8X Collection, a new line of lab-grown diamonds combining top color, clarity, and cut precision. The collection is certified by GCAL by Sarine using the GCAL 8X Ultimate Cut Grade, a rigorous standard for evaluating diamond light performance, finish, and optical symmetry.

The launch brings together D color and Flawless (FL) and Internally Flawless (IF) clarity with a verified top-tier cut grade. While achieving D color and Flawless clarity is rare on its own, combining it with strict 8X cut criteria represents an exceptionally high standard.

According to industry estimates, FL and IF clarity lab-grown diamonds account for approximately 1–3% of global production, with only a small subset meeting the requirements for GCAL 8X certification. Grown Diamond Corporation has assembled a curated inventory of more than 1000 diamonds that meet this combined standard.

Each diamond in the collection is accompanied by a GCAL 8X certificate, which includes optical performance analysis, imaging, and a money-backed grading guarantee, providing independent validation of both quality and performance.

For retailers, this translates into a meaningful competitive advantage. These diamonds represent the rarest combination of modern science and craftsmanship, supporting higher average selling prices while helping retailers clearly differentiate their offering in the market.

Grown Diamond Corporation CEO Viral Mehta said the launch reflects the company’s focus on pushing the boundaries of what is possible in lab-grown diamonds. “This launch represents a defining moment for Grown Diamond Corporation. We have focused on pushing the boundaries of what is possible in lab-grown diamonds, achieving consistent D color and Flawless clarity at scale. By pairing this with GCAL 8X certification, we are now delivering a product that represents the highest level of precision, performance, and rarity in the market.”

Angelo Palmieri, president of GCAL by Sarine, said the collection represents an exceptionally high standard in the market. “Grown Diamond Corporation has achieved something truly exceptional with this collection. Combining D color, Flawless clarity, and 8X cut is an extremely high bar. We are proud to provide the independent certification that supports and validates this level of precision, giving retailers and consumers confidence in what they are purchasing.” The collection includes diamonds ranging from 1.00 to 5.00 carats in shapes including round, oval, princess, pear, marquise and radiant. It will be showcased at JCK Las Vegas 2026, Booth #7141, and is available through Grown Diamond Corporation and leading industry trading platforms.
