Our Story

Louped Jewelry is led by Danielle Mascio, a certified gemologist appraiser with over 20 years of professional experience in fine jewelry, diamonds, gemstones, appraisal, authentication, and estate acquisitions.

Operating through a working gemological laboratory, Danielle performs daily professional appraisals, gemstone analysis, diamond grading, authentication, valuation, and estate jewelry evaluation—bringing real-world expertise to every piece offered through Louped Jewelry.

Her background spans professional gemology, appraisal, goldsmithing, bench jewelry experience, buying, selling, restoration, and decades of hands-on work in the jewelry trade. This technical expertise, combined with deep market knowledge, allows Louped to source exceptional jewelry with confidence, precision, and uncompromising standards.

Louped Jewelry specializes in authenticated antique jewelry, estate fine jewelry, signed designer jewelry, important diamonds, rare gemstones, and exceptional pre-owned luxury pieces. Every item is personally sourced and professionally evaluated for authenticity, craftsmanship, condition, and lasting value.

Danielle’s passion for jewelry began as a teenager working in jewelry stores, where an early fascination with gemstones evolved into a lifelong profession. Years of handling, studying, appraising, and evaluating fine jewelry have shaped a discerning eye for quality, rarity, and historical significance.

While antique jewelry remains a particular specialty—including Victorian jewelry, old mine cut diamonds, rose cut diamonds, Art Deco treasures, and heirloom pieces—Louped also offers exceptional signed estate jewelry and collectible modern luxury pieces for sophisticated collectors and clients.

Clients of Louped Jewelry are not simply purchasing jewelry—they are benefiting from professional gemological expertise, authentication, and carefully sourced acquisitions selected to exacting standards.

Whether you are a collector, buyer, seller, or searching for an exceptional piece, Louped Jewelry offers expertise, transparency, and jewelry selected with the highest professional standards.
