In an industry long defined by tradition, Stephanie Binder set out to change the narrative—one diamond at a time. As a second-generation, certified gemologist and founder of Boston Diamond Company, she built her boutique on Newbury Street to showcase female perspectives in a male-dominated world, creating an intimate, appointment-only destination where craftsmanship meets connection. Every piece is locally handcrafted and ethically sourced, designed to reflect each couple’s love story while delivering the caliber of artistry found at high-end retail jewelers, such as nearby neighbors Cartier and Tiffany & Co. The result? A woman-led fine-jewelry house that turns proposals into heirlooms and clients into lifelong friends.
Tell us about your background and how you ended up forming your company.
Boston Diamond Company was born from a deep belief that buying an engagement ring should feel extraordinary. I founded the company after years of seeing how impersonal and overwhelming the fine-jewelry world could feel—especially for women. As a certified gemologist and a designer who grew up watching my mother overcome every obstacle, I built my company with a vision that was rooted in trust, education, and craftsmanship. We started as a small boutique, and we’ve grown into Boston’s premier fine-jewelry destination. Located on the first block of Newbury Street, right next to Cartier, Tiffany, and Van Cleef, we’ve built a reputation for creating pieces that are never mass-produced, always hand-selected, and designed to last for generations.

Take us through your process.
From the moment the client steps through the doors, they feel we’re not a typical jewelry store. It’s a curated appointment-only experience, designed for connection, personalization, and creativity. Every consultation is private and intentional, so couples feel guided and supported through every single decision. When they come in, we take the time to learn their story, their style, and what matters most to them. Then we pair that with our expertise in design gemology. What makes our store unique is that we are all gemologists, so that makes our craftsmanship super refined and brings our vision to life. My favorite part of this work is watching a client’s face light up when they see their ring, knowing it’s not just a piece of jewelry but a chapter in their love story that will be treasured for a lifetime.
Let’s talk logistics: How far in advance do you prefer couples come to see you?
For engagement rings, we recommend couples schedule their appointments three to four months before their ideal proposal date. This allows time for personalized design, diamond selection, and hand-fabrication. For wedding bands, we recommend three to six months because there are a lot of minor details when planning a wedding. The rings and the dress are the most important.

What ring styles are in high demand?
One of the most in-demand designs right now is the oval-cut diamond. We have seen more modern designs, but minimalism is what’s been very popular for timeless romance. Think of a solitaire engagement ring with a hidden halo, or a bold or classic cut like an emerald cut with a platinum band. These are pieces that feel of the moment and also timeless and forever. Our value is our belief in fine jewelry: It shouldn’t ever feel generic, whether creating a bespoke engagement ring, custom wedding bands, or a beautiful, redesigned, treasured heirloom piece. It’s crafted for beauty and durability. Our clients trust us not just to make a ring, but to create a legacy piece.
