Stone & Strand Fine Jewelry: Our Mission




Stone & Strand is an exclusive fine jewelry destination that brings the thrill of discovery to online shopping.


Our Founder, Nadine McCarthy conceived the site as a bridge between the accessibility of the Internet and the charm of culling through rare treasures in Parisian boutiques, flea markets in Argentina or artisan shops in Brooklyn.


Her international upbringing in locales such as Singapore, London and Buenos Aires exposed her to myriad alluring venues ripe with the anticipation of unearthing a rare treasure.


Stone & Strand’s mission is threefold: to recreate this nostalgic experience online, marry it with the intimate attention of a personal shopper and concierge and present it with an inspiring editorial point of view that forges connections between customers and our curated portfolio of designers.


We believe that jewelry is intensely personal, and we think your shopping experience should mirror that sentiment. Imagine exploring the exotic labyrinth of a Moroccan souk in the comfort of your living room – only with more guidance and less snake charming.


We at Stone & Strand strive to reinvigorate jewelry shopping with our three-pronged approach, creating an entirely new breed of ecommerce platform.


Our mission is to make exquisite jewelry design accessible to shoppers all over the United States. We begin by searching for true craftsmen, individuals with a unique aesthetic, unparalled craft and a true personal story to tell. Our designers often have a cult-like private client base, collectors who return for a new piece every single year, customers who understand that their work is truly art. We believe in supporting both local as well as emerging designers, and our initial group of jewelry designers are all based right here in the USA.



We populate Stone & Strand with the best pieces in our jewelers' collections, and pair them seamlessly in our “Features” section to create a greater context of fashion and lifestyle that puts your shopping experience into a contemporary perspective. We additionally strive to educate, maintaining a body of comprehensive style and jewelry knowledge that can transform even the most casual hobbyist into a connoisseur. The jewelry industry is often a veiled and complicated place, and we seek to create transparency and trust by ensuring that you always know just as much as we do. 



But our work doesn’t stop there. We offer a suite of comprehensive services designed to recreate the intimate attention you’d expect from something between an expert and a best friend. We pair each and every shopper on our site with a personal jeweler, someone who is knowledgeable, and can take them through the entire process, from finding the perfect piece with our personal shopping and gift recommendation services, to custom design match making when what you want doesn't yet exist. We see your purchase as merely the beginning of our relationship and will work with you to ensure that each piece is cared for in every way, keeping it in the exactly the same exquisite condition as it arrived in on day one.


Based in New York, our founding team has many years of experience in fine jewelry, media, and business coming from W Magazine, Tiffany, and John Hardy.


We have worked alongside top jewelers such as Ippolita, Monique Pean, Irene Neuwirth, Philip Crangi, Melissa Joy Manning amongst others.


Finally our staff includes a certified gemologist trained at the Gemological Institute of America, as well as highly experienced personal shopping and customer service executives.


Standing behind the promise of "Exquisite Pieces, Intimate Service", Our mission is to help shoppers discover and get inspired by exquisite pieces of jewelry, coupled with a truly intimate service proposition that takes personalized care to the next level.


Our company seeks to define itself through our core values of Service, Elegance, Creativity, Transparency and Support of the Arts. 


We work hand-in-hand with our jewelry designers, who represent the very best of their craft and aim to support both local artisans based right here in the United States, as well as up-and-coming emerging designers.

Casually speaking, fine jewelry is defined as pieces made of precious metals, like gold and silver, and set with precious or semiprecious stones. However, there’s a more technical side to the definition, classifying everything from cut to color, that we use to ensure you get access to only the very best.

Fine Jewelry

Fine Jewelry is formally defined as pieces made of precious metals, like gold and silver, and set with precious or semi-precious stones. However, here at Stone & Strand we also use the definition of craftsmanship. We believe in creativity, innovating with different materials and pushing the boundaries of jewelry creation through design, technology and experimentation. Whether its crafted with traditional metals, or less traditional materials such as the finest wood our pieces of jewelry represent the very best of their kind.
