Every Piece, a Provenance
DIA specializes in estate and secondhand fine jewelry, alongside select modern creations.
Each acquisition is authenticated, inspected, and chosen for design integrity, craftsmanship, and condition.
AUTHENTICITY & CARE
Our Standards
Every DIA piece is handled with precision and respect — from intake to inspection, certification, and final presentation.
All jewelry — whether vintage, estate, or newly produced — undergoes comprehensive evaluation and certification at our partner gemological lab before dispatch. Each piece is accompanied by its lab report and internal documentation, verifying metal purity, gemstone authenticity, and condition.
Minor traces of wear are expected and respected as part of a piece’s provenance. Any notable marks or variations are always disclosed prior to sale.
We never offer plated, vermeil, or gold-filled jewelry — only solid gold, natural gemstones, and certified fine materials.
Every piece passes through strict quality control after certification to ensure it meets DIA’s collector-level standards of craftsmanship, integrity, and condition.
Jewelry Care
Fine jewelry deserves care equal to its design.
We recommend the following:
- Avoid exposure to harsh chemicals, perfume, or chlorinated water.
- Store pieces individually in soft fabric or their original DIA packaging.
- Clean gently with mild soap and warm water; pat dry with a lint-free cloth.
Normal wear, surface patina, or minor scratches are part of natural use and not considered defects.
We do not offer post-purchase inspections or complimentary repairs.
Curation is permanence — care is respect.
