The Meaning Behind The Name ‘Black Diamond’

Over the years, a common question has arisen, “What is the significance of ‘Black Diamond’ in your company name?” We are far from jewelry experts so let us explain the meaning.

The founders brainstormed many ideas. Black Diamond Realty was proudly chosen for several reasons. The first motive represents the deepest meaning. The founding members are passionate about their deep roots in West Virginia. For over a century, coal has served as West Virginia’s black diamond. It has been the lifeblood for many West Virginia communities. Similar to coal’s economic benefits for many West Virginia families, Black Diamond Realty aims to provide exceptional service while providing economic benefits via job creation and wealth building opportunities.

The second meaning is more recreational. The two primary founders of Black Diamond love to ski. Similar to navigating commercial real estate deals, black diamond rated slopes can be challenging with curveballs and potential pitfalls. As trained professionals, our team is proficient in helping our clients avoid economic dangers when directing a successful deal.

The third meaning pays homage to the rivalry that is West Virginia University and Virginia Tech. While the Black Diamond founders were all born and raised in Morgantown, WV (home of WVU) and two of them attended the home-state university for portions of their post-secondary education, David Lorenze committed a Morgantown sin by choosing to attend Virginia Tech University. Virginia Tech and West Virginia University are bitter rivals, particularly during their Big East Conference days. Each year, when they played in football, the winning team took home the ultimate prize, the Black Diamond Trophy. With all of these important things in mind, the name Black Diamond Realty was thoughtfully chosen and the company was born.

A Foundation Built Upon Tradition.

David Lorenze

David’s Morgantown roots include family and friends with value-driven and entrepreneurial identities. Growing up and living in Appalachia, surrounded by these individuals, supported David’s growth into the individual he is today.
