Authentication & Certification Process

How Jewellery & Watches Are Professionally Assessed

Transparency at Every Stage

At Clarindon Jewellers, authentication and certification are central to trust. This page explains how jewellery and watches are assessed, what checks are carried out, and how findings are disclosed clearly to clients.

Our process prioritises accuracy, transparency, and realism.


What Is Authentication?

Authentication is the process of confirming:

  • Identity of a watch or jewellery piece

  • Materials and construction

  • Brand and model (where applicable)

  • Consistency with known references

Authentication is based on professional expertise and available evidence.


Jewellery Authentication Process

Jewellery assessment may include:

  • Metal testing

  • Gemstone identification

  • Construction analysis

  • Hallmark verification

Findings are explained clearly, including any limitations.


Watch Authentication Process

Watch assessment may include:

  • Visual inspection of case, dial and movement

  • Reference and serial verification where possible

  • Comparison with known manufacturer standards

  • Functional checks

Where full certainty cannot be achieved, this is stated openly.


What Certification Means

Certification indicates that:

  • A professional assessment has been carried out

  • Findings are documented and disclosed

  • Condition and originality have been considered

Certification is not a guarantee of future performance or value.


Transparency & Limitations

Some items:

  • Lack original documentation

  • Have undergone historical servicing or repair

  • Cannot be fully verified due to age or rarity

We explain what is known — and what cannot be confirmed.


Why This Matters to Clients

A clear authentication process:

  • Reduces risk

  • Supports insurance and valuation

  • Builds confidence in ownership

Trust comes from honesty, not certainty.
