Mark and Nataliya Hadley have a combined 50+ years experience in the fine jewelry industry. With a shared passion for exceeding each customer’s expectations, they collaborate with the world’s most respected diamond wholesalers and top jewelry designers to create unforgettable, beloved jewelry pieces, within your timeline and budget.

Mark and Nataliya live in Denver and enjoy spending free time with their son, four daughters and entertaining friends.

For more than 35 years, Mark has created a name for himself in the jewelry industry. His career began, when as a young man making his way across country, he found himself in need of employment to replenish a dwindling bank account. He took what he thought would be a temporary sales position at a jewelry store, but the rest, as they say, is history.

Mark loved creating a relationship with customers and assisting them to select the perfect piece of jewelry; he soon became the top salesperson. This early success led to Mark’s promotion to store manager, district manager and, ultimately, regional vice president of an 8-state corporation. In all of these positions, he excelled.

Nataliya’s experience was, remarkably, quite similar. She was introduced to the jewelry industry as a part-time salesperson after high school. Again, a passion for fine jewelry combined with her innate desire to exceed the expectations of her clients led to her exceptional success. She was the youngest person in the history of the corporation to be promoted to a store manager position. Her unprecedented achievements continued as she was transferred to stores of increasing responsibility to maximize their performance.
