ABOUT JACK & JEWELZ
Jack & Jewelz is a female-founded, purpose-driven jewelry brand on a mission to bring safe, stylish, and hypoallergenic accessories to the next generation. Founded by Jacqueline Cohen, a GIA-certified geologist and veteran of New York City's iconic Diamond District, the brand was born from decades of fine jewelry experience - and a deeply personal purpose.

She’s a GIA Certified Gemologist, a trained finance professional, and a trusted source for timeless, high-quality pieces.
Inspiring the Next Generation of Girl CEOs
But when her daughter Jewel was diagnosed with Juvenile Rheumatoid Arthritis, Jackie’s mission evolved. She didn’t just want to sell jewelry — she wanted to build something that mattered.
Jackie launched Jack & Jewelz as a way to create safe, hypoallergenic earrings for girls like Jewel — and to teach her daughter what it means to be strong, confident, and entrepreneurial. Now, through the Ambassador Program, Jackie is mentoring a new generation of girl CEOs, sharing her “Gems of Wisdom” from decades of real-world sales, branding, and business-building.
Jackie believes jewelry is more than an accessory — it’s a gateway to confidence, purpose, and personal power. She’s not just designing earrings. She’s designing futures.
After more than 20 years designing bespoke diamond pieces for high-end clients, Jacqueline was inspired by her daughter Jewel, who dreamed of designing her own jewelry line. Together, they set out to create a collection that was not only beautiful but safe for sensitive ears - especially for kids and teens.
As a mom and master jeweler, Jacqueline knew the stories too well - little girls with infected ears, painful reactions, and the heartbreak of having to re-pierce. She also knew there had to be a better way.
