Nancy Jain
Founder & Owner

I am Nancy, founder and owner of NNJ Designs! This has been the hardest intro to write but I will try my best!

I am a mom to a beautiful baby boy, Julian aka Jules, a gorgeous golden retriever, Kushi, and this little jewelry shop, NNJ Designs.

I discovered jewelry in a professional capacity during my college years. I am an Ohio State alumni, with a major in Finance and Political Science. While studying, I began working for a small jewelry company that needed help at gem trade shows. This gave me the opportunity to travel to all across the US and meet many jewelry lovers and experts. They taught me soooo much about jewelry and really helped light the fire with which this business was forged. Formal training from the GIA helped round out my education, but nothing taught me nearly as much as the hands-on experience I got networking with all of the incredibly passionate jewelry lovers that I now have the pleasure of designing for!

I can’t wait to spend a lifetime of curating fine gems, designing beautiful and meaningful pieces, and growing my jewelry family.

Our Detail-Oriented Bookkeeper and Package Manager!

Meet Adi, the meticulous guardian of our books and the mastermind behind managing all incoming and outgoing packages at NNJ Designs 🥰

My connection with Adi goes back to the dance troupe that I joined last-minute, fresh out of high school. Now, let's be honest, my dancing skills were tragically lacking, but Adi took me under her wing and prepared me for the competition. While my dancing ability didn't improve much, it ignited a lifelong friendship between us. It's been over 16 years of shared experiences, and we're excited for the adventures that lie ahead.

Adi is not only a brilliant bookkeeper, but she's also one of the most adventurous and fearless individuals I know. Throughout her life, she has explored the world, immersing herself in diverse cultures, people, and cuisines. She truly embodies the spirit of a global citizen, and I feel honored to have her by my side every day.

With Adi's attention to detail and her passion for excellence, you can rest assured that your books are in capable hands and that your packages will be managed with utmost care. She brings her dedication and expertise to every task she undertakes, ensuring smooth operations and top-notch customer satisfaction.

PS: She is also the sister of our NEWEST team member, Priyanka!
