Jewellery found him before law did. It started by watching someone work — the process, the materials, the way something raw becomes something people wear for the rest of their lives. He got curious, started figuring it out himself, and never really stopped. That's how most things in Jeffery's life have gone. He doesn't wait to be taught. He learns by doing.

Seeing the pride and happiness on his friends’ faces when they received their engagement ring to propose to their future partner became the most fulfilling part of his work. That experience led Mad Minerals to shift its focus toward exceptionally well-crafted engagement rings, specializing in lab-grown diamonds that offer both affordability and a true sense of luxury through high-purity gold. Guided by strong values, Jeffery thoughtfully considers ethics, environmental impact, and the emotional significance behind every piece—striving to make the world a better place through beauty, responsibility, and meaningful designs.
