MEET MARK
My passion is guiding clients to discover the perfect hand-crafted piece that enriches their fine jewelry collection while delivering exceptional value.
With over 45 years of experience, I take pride in offering superior diamonds at the best prices—consistently outperforming both retail jewelry stores and online competitors.
My journey began decades ago in the world of wholesale diamonds, where I supplied fine jewelry stores throughout the United States, Mexico, Peru, Panama, and Australia—personally overseeing more than $25 million in diamond sales. Over time, I evolved from a global diamond dealer to a direct manufacturer, mastering every stage of the process—from sourcing rough stones to cutting and polishing them to perfection.
That experience gave me an unshakable appreciation for quality, precision, and integrity—values that continue to guide everything I do today. It also allowed me to build relationships with some of the world’s most respected diamond suppliers and craftsmen, giving me the unique ability to bring world-class diamonds and designs directly to clients who value authenticity and excellence.
Whether I’m creating a custom engagement ring or helping someone find the perfect heirloom piece, my goal is always the same: to provide a deeply personal experience rooted in honesty, knowledge, and genuine care.
Thank you for choosing Mark S. Daffner — where jewelry is art.

A PERSONALIZED BOUTIQUE SHOPPING EXPERIENCE
In today’s world of large online retailers and automated sales, the personal touch has nearly disappeared. What makes my approach different is the relationship I build with each client—rooted in trust, expertise, and genuine understanding.
When you contact me, you’re not speaking to a call center or chatbot—you’re speaking directly with me. Every question, every consultation, and every recommendation comes from decades of hands-on experience and a sincere desire to help you find the perfect piece.
I take the time to understand what matters most to you—your taste, your budget, and your story. Whether you’re choosing an engagement ring, a custom design, or a timeless gift, I’ll guide you personally through every step of the process with honesty, insight, and care.
My goal is to provide the warmth and attention of a private jeweler with the value and expertise that only comes from a lifetime in the diamond trade—making your shopping experience as meaningful as the jewelry itself.
