Our Beginning

Black Jack began as a homegrown Indian brand built on craftsmanship, innovation, and ethical responsibility. Today, it operates globally through its United States entity, delivering fine jewelry designed for modern values without compromising tradition or quality.

Brand Philosophy: Confidence, responsibility, and meaning — crafted into every piece.

Brand Identity and Legal Structure

Black Jack is a trademark-registered brand in India, recognized for innovation in lab-grown diamonds, sustainable manufacturing, and precision jewelry design.

Black Jack LLC is the legal owner and operator for the United States market, headquartered in Sheridan, Wyoming. Black Jack LLC manages U.S. website operations, customer contracts, compliance, payments, and international business governance.

From Growing to Glowing

Unlike conventional jewelry brands, Black Jack controls the journey from creation to completion.

We grow lab-grown diamonds through our own facilities using advanced technology. Each diamond is cut and polished in-house, ensuring consistency, brilliance, and precision across designs.

In-House Control

Diamond growing, cutting, polishing, design, manufacturing, and final quality checks are handled within our workflow.

Design Range

Round, princess, oval, cushion, radiant, emerald, fancy shapes, and specialty colors depending on design requirements.

Memory Diamonds

Black Jack offers Memory Diamonds created through a controlled, laboratory-based carbon integration process. These diamonds are designed to represent personal connection and remembrance, transformed into a lasting symbol through lab-grown technology.

Memory Diamonds are real diamonds created under regulated conditions and contain no biological material in the final gemstone. Each order is processed with confidentiality, documentation, and ethical care.
