Certification & Authenticity

Every piece from Maison Éclat comes with comprehensive documentation ensuring authenticity, quality, and provenance.

Hallmarking

All Maison Éclat pieces are hallmarked in accordance with UK Assay Office standards, guaranteeing the precious metal content of every item.

Our hallmarks include the maker's mark, metal purity mark, assay office mark, and date letter, providing complete traceability and authenticity.

We work exclusively with the London Assay Office, one of the world's oldest and most respected hallmarking authorities, established in 1300.

Gemstone Certification

All diamonds and precious gemstones are accompanied by independent certification from internationally recognized gemological laboratories.

We primarily work with the Gemological Institute of America (GIA) and the International Gemological Institute (IGI), ensuring the highest standards of grading and authentication.

Each certificate details the stone's characteristics including carat weight, colour, clarity, cut quality, and any treatments or enhancements.
