Hartley Vandâr began in 2020 as a private jeweler by referral in Highland Park, Texas. Specializing in the world’s top 0.05% of diamonds, each Hartley Vandâr piece is one of one in the world. Gaining recognition for meticulous attention to detail and craftsmanship, Hartley Vandâr clientele spread entirely by word of mouth from Texas to New York, Connecticut, California, Great Britain, and France among others. His jewelry has become highly sought after by collectors.

Focusing on High Jewelry that utilizes natural diamonds, Hartley Vandâr spends months sourcing and cutting the absolute rarest and finest diamonds in the world for each piece. Unlike other jewelry houses, Hartley Vandâr does not mass produce jewelry — every piece is one of one and made by hand.

With increasing demand for Lab Grown diamonds, Hartley Vandâr expanded and began working with private clientele on lab grown diamond jewelry as well. In 2025, the demand became so strong that Hartley Vandâr announced its first line of Lab Grown High Jewelry that will be available to the public as individual, exclusive pieces. Just as with any natural diamond piece, these designs incorporate the absolute finest and rarest lab grown diamonds.

The first collection of Hartley Vandâr High Lab Grown Diamond Jewelry debuted in March 2025 with Ferrari at Ferrari Art Week in Scottsdale, Arizona. Hartley Vandâr was then selected as just 1 of 100 jewelers from around the world to exhibit at the prestigious Hampton’s Jewelry Show this July, 2025. He’s been featured in the National Jeweler, exhibited at museums across the US, and is becoming one of the youngest, most influential jewelry designers today.
