Authenticity Guarantee

Buying antique and vintage jewelry requires trust, expertise, and transparency.

We take this responsibility seriously. Every piece we offer is carefully selected, authenticated, and verified to ensure you purchase with complete confidence.

Expert Authentication

Each jewel is individually examined by John, a trained jewelry expert with qualifications in gemmology and antique jewelry.

Our authentication process includes:

  • Verification of period and style (1800–1990)
  • Examination of precious metals (gold, platinum, silver)
  • Analysis of stones (natural, fine or semi-precious)
  • General condition check

We only offer genuine antique and vintage pieces — never reproductions or modern copies inspired by historical styles.

Thorough Inspection & Restoration

Before being listed on our boutique, each piece undergoes a complete inspection.

When necessary, we carry out careful and respectful restorations to preserve the integrity, character, and value of the jewel. Any work is performed with the utmost attention to maintaining the original craftsmanship and materials.

Our goal is simple: to offer jewelry that is ready to be worn, cherished, and passed on.

Certificate of Authenticity

Every purchase is carefully examined, authenticated, and comes with a Certificate of Authenticity, prepared by us after a detailed evaluation.

This certificate confirms:

  • The estimated period
  • The materials and stones
  • The authenticity of the piece
  • Our expert assessment

It serves as a lasting guarantee of the value and provenance of your jewelry.

Our certificate of authenticity confirms the expert examination and authenticity of each piece.

Insurance & Valuation Information

Our certificate of authenticity confirms the expert examination and authenticity of each piece.

For insurance purposes, the purchase invoice may be used as a reference when declaring your jewelry to your insurer.

Fair & Transparent Pricing

We believe authenticity also means honest pricing.

Our prices reflect:

  • The true nature and quality of each piece
