At Black Jack, we believe jewelry should do more than shine—it should empower. That’s why our brand proudly carries the slogan: “Wear the Power.”

Founded as a homegrown Indian brand, Black Jack is a trademark-registered parent company recognized for its innovation in lab-grown diamonds and ethical jewelry craftsmanship. To expand our global reach, we established a U.S. branch—Black Jack LLC, headquartered in Sheridan, Wyoming.


💎 Our Strength: From Growing to Glowing

Unlike most, we don’t just sell lab-grown diamonds—we grow them ourselves in India using advanced sustainable technology. Every diamond is cut and polished in-house at our own factory, ensuring premium quality and precision across all shapes and styles:

  • Fancy Shapes & Colors: Pear, Marquise, Asscher, Heart & more

From loose diamonds to luxurious designer pieces, Black Jack crafts everything from the ground up.
