The Jewel Box

The glittering Jewel Box is housed in a striking oval-shaped glass cylinder, where luxury pro shop meets Madison Avenue chic. Artfully integrated, The Jewel Box is a stunning yet serene space where members can browse, shop, and dream among Brandon Boswell Diamonds’s hand-picked selection of exceptional jewelry.

With more than 40 years of experience in luxury, Brandon Boswell brings a rarefied combination of discriminating taste, global access, and world-class client service to BIGHORN.

His work takes him across the world, sourcing exceptional diamonds and gemstones through his trusted global network, always with uncompromising standards of quality, beauty, and value. Clients rely on his ability to discover the extraordinary, and he is known for offering only the best of the best to a discerning clientele who appreciate excellence as much as he does.

But what truly defines Brandon is the experience he creates. Warm, welcoming, and genuinely invested in every relationship, he is known for establishing meaningful, personal connections—many of which evolve into long-standing friendships. BIGHORN Members will find that he approaches every interaction with integrity, sincerity, and a deep respect for trust as the cornerstone of great service. “This is a small community and a small industry,” Brandon says. “In life and in business, you are only as good as your word.”

At The Jewel Box, Brandon and his team are delighted to share their expertise, offering guidance on diamonds, colored gemstones, craftsmanship, GIA knowledge, design, and the latest breakthroughs in fine jewelry.

Brandon considers it a true privilege to be part of the BIGHORN community, where generosity and compassion run deep.
