Where it all began...Marina was always watching her father, Tony, as he would melt gold into the design process to create hand-crafted jewelry. Their bond and love of jewelry design is what launched the Hartmann Jewelry brand it is today.
This August, Marina Hartmann-Castillo and her father, Tony Hartmann, mark 30 years of serving Houston through craftsmanship, personal relationships, and trusted guidance. What began as a commitment to quality remains a family-led business built on care, artistry, and integrity.
Many clients first visit for a repair and return to share their life’s most meaningful moments.
Every custom piece begins with a conversation.
Whether starting from an idea, an heirloom, or a milestone worth marking, we guide each design from concept to finished creation with precision and heart.
