For over four decades, Riggs Oil Company and Black Diamond Markets have proudly fueled the communities of Southwest Virginia. What began in the early 1970s as a family-owned fuel business grew into a trusted regional brand, built on reliability, hard work, and a deep respect for the people we serve.

With the launch of Black Diamond Markets in the early 1980s, our focus expanded beyond fuel—creating welcoming, convenient destinations where customers can count on quality products, friendly service, and hometown values. Today, our stores continue to evolve while staying true to what matters most: integrity, community, and customer-first service.

We’re proud of our roots, committed to our future, and dedicated every day to serving our customers with consistency, care, and pride.
