About Serpentine Jewels
The Modern Private Jeweler
Serpentine Jewels is a gemstone-driven fine jewelry house. Conceived as a personal jeweler, we represent a modern evolution of the private model - integrating deep gemological expertise, refined design, and personal advisory into one seamless practice.
Operating as a comprehensive resource for all fine jewelry needs, our work spans bespoke commissions, signature collections, and carefully curated vintage. This breadth is intentional: it reflects how our clients collect - not in silos, but mixing eras, categories, and styles to shape an aesthetic that is entirely their own.
Gemstone Expertise
Through longstanding relationships within the global gem trade, Serpentine provides unparalleled access to some of the world’s finest diamonds and colored gemstones, from antique diamonds and Colombian emeralds to Australian black opals and velvety sapphires. We hand-select for beauty, character, rarity, and value, whether sourcing for a private client or shaping our signature collections.
Art + Science
At Serpentine, our design work is defined by its range. While our signature aesthetic is rooted in distinctive gemstone colors, unexpected shapes, and unconventional orientations, we are just as devoted to the art of the timeless classic - bringing the same exacting eye to a diamond stud as we do to our most ambitious commissions. Whether asserting our point of view or refining yours, our world-class team of master craftspeople, gemologists, designers, and client advisors ensures every piece is executed with careful attention to scale, wearability, and the highest caliber of craftsmanship.
Lifetime Advisory Model
Acting as a long-term architect of your personal collection, we provide clear, confident counsel at every step of your jewelry journey. Because we are not confined by the limits of a traditional jewelry case, the possibilities are expansive. We offer trusted guidance through it all—whether designing a sculptural engagement ring, reimagining a family heirloom for modern wear, or engineering a highly articulated diamond collar.
With an atelier in Greenwich, CT, and a studio in New York City, we guide clients seamlessly in person or from afar. Celebrated for our distinct approach to fine jewelry, Serpentine is regularly featured in publications such as The New York Times, Town & Country, WSJ Magazine, and People.
We believe that jewelry is more than just adornment - it is tangible proof of a life lived and a reflection of the chapters that shaped it. True to our name, we embrace the serpent as the ultimate symbol of eternity and renewal - partnering with you to shape the legacy you will wear, treasure, and one day pass on.
Our Team
Serpentine is led by founder Ali Galgano, a GIA graduate gemologist and designer whose dual expertise—the scientific rigor of gemology paired with the creative intuition of design—sets the standard for everything we do. Behind Ali is a carefully assembled team drawn from the most respected names in fine jewelry, including Tiffany & Co., Van Cleef & Arpels, Sotheby's, and top independent jewelry designers. Every member of the Serpentine team is selected for their expertise, judgment, and commitment to the white-glove experience our clients expect at every touchpoint. Whether you are working directly with Ali or with any specialist on our team, you can be confident you are in the hands of people who bring deep technical knowledge, refined taste, and an unwavering attention to detail to every project they touch.
