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 trusted 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 and estate jewelry, and exceptional gemstones sourced from around the world. This breadth is intentional: it reflects how our clients collect - not in silos, but across eras, categories, and styles to build collections that feel uniquely 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 blue 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 equally 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 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. We believe jewelry should feel personal, not intimidating, and that great collections are built over time through curiosity, expertise, and thoughtful guidance. 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, sourcing a rare gemstone, discovering a vintage treasure, or engineering a highly articulated diamond collar.
With an atelier in Greenwich, Connecticut, 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 jewelry is more than just adornment - it is beauty, self-expression, celebration, memory, and legacy. True to our name, we embrace the serpent as a symbol of transformation, renewal, and eternity - partnering with clients to create pieces that mark life's chapters and become part of the stories they carry forward.
Our Team
Serpentine Jewels 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 some of the most respected names in fine jewelry, including Tiffany & Co., Van Cleef & Arpels, Sotheby's, and leading 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 commitment to helping you build a collection that feels distinctly your own.
