Fifth Avenue Curation
Our Roots
From the Heart of Fifth Avenue
ABC Gem Store draws its name and spirit from the historic and bustling trade on Fifth Avenue, New York City. Our journey began in 1992, founded by Arthur B. Carter, a master gemologist whose precision and eye for rare, exquisite gemstones earned him a distinguished reputation among early Manhattan collectors.
His deep-rooted expertise in grading and valuation naturally evolved into an international trading boutique. In 2016, the legacy was formalized as an active partnership with his two children, Benjamin Carter and Clara Carter, bringing a modern digital focus and strong ethical sourcing commitments to the brand.
Today, ABC Gem Store operates in compliance with US trade regulations, partnering with leading laboratories such as GIA, and is committed to upholding the highest standards of integrity and excellence in the luxury jewelry industry.

What We Stand For
Ethical Sourcing
We ensure fair wages, safe working conditions, and minimal environmental impact at every stage of our supply chain.

Our commitment to the planet means responsible mining practices and active land rehabilitation programs.

Full traceability from mine to market. Every gem comes with documentation of its origin and journey.

Traceability & Integrity
Our Sourcing Philosophy
We maintain a direct pipeline to artisanal mines worldwide. By purchasing rough material at the source, cutting under ethical, fair-labor conditions, and verifying each stone through independent labs like the GIA (Gemological Institute of America) and GRS (GemResearch Swisslab), we ensure complete mine-to-market traceability and value.
Every acquisition conforms to our strict guidelines for ethical provenance, ensuring that our partners, local mining communities, and clients benefit equally from these natural treasures. We do not deal in synthetic, lab-grown, or simulated stones.
GIA & GRS Certified
Every major gemstone is independently graded by industry-standard laboratories.
Mine-To-Market
Direct sourcing skips middleman premiums and guarantees verifiable origin.
