Have you evaluated the credentials and expertise of the jewellers performing the restoration work?

Yes. Checking the credentials and practical expertise of the jeweller carrying out restoration is an important part of protecting your piece. Jewellery restoration can involve delicate, irreversible work, so the person assessing and repairing it should understand precious metals, gemstones, settings, construction methods and the limitations of older or unusual jewellery.

Relevant qualifications are useful, but they are only one part of a proper assessment. Experience with the specific type of restoration is equally important. A jeweller who regularly handles worn settings may not have the same expertise in rebuilding antique mounts, repairing intricate hand engraving, restoring enamel or working with fragile gemstones. Ask whether the proposed restorer has dealt with comparable pieces and can explain the techniques that may be required.

What to check before work begins

• Whether the jeweller has recognised jewellery-making, gemmology or watchmaking training relevant to the work involved.
• How long they have been carrying out restoration, repair or remodelling work.
• Whether they have experience with the materials in your piece, such as platinum, gold, silver, antique alloys or unusual gemstones.
• Whether the work is completed in-house or passed to a specialist, and who will be responsible for inspecting the finished item.
• Whether the jeweller can explain the proposed repair in clear terms, including any risks and limitations.
• Whether the business has appropriate insurance, secure handling procedures and a documented process for recording items in its care.

A reputable restoration assessment should begin with a close examination of the jewellery, rather than an immediate promise that every mark or fault can be removed. The jeweller should identify structural weaknesses, previous repairs, worn claws, thin sections of metal, loose stones, damage to hinges or catches and any signs that the piece has been altered. For older jewellery, preserving original features may be more appropriate than making it appear entirely new.

Ask for a clear condition report

Before authorising work, request a written description of the item and its condition. This should record the materials, gemstones, identifying features, existing damage and the restoration proposed. Photographs can also help document the piece before it leaves your possession. A proper record reduces the risk of misunderstanding and provides a useful comparison when the jewellery is returned.

The estimate should distinguish between essential structural repairs and optional cosmetic work. For example, rebuilding a worn setting may be necessary to hold a stone securely, while polishing or refinishing may be a separate choice. The jeweller should tell you if cleaning, polishing or heat could affect a gemstone, patina, engraving or other original detail.

Evaluate the explanation, not just the credentials

Expertise is demonstrated by the quality of the assessment and the reasoning behind the recommendation. The jeweller should be able to explain:

• What caused the damage or deterioration.
• Which parts can be repaired, replaced or strengthened.
• How the proposed technique will protect the design and gemstones.
• Whether the restoration will alter the appearance, weight, dimensions or originality of the piece.
• What risks apply, particularly where the jewellery is fragile, hollow, antique or previously repaired.
• How the finished item will be checked for security, alignment, movement and surface quality.

Be cautious if a jeweller dismisses questions, recommends extensive work without examining the piece properly, cannot identify the materials involved or guarantees an identical result before assessing the jewellery. Restoration often involves judgement, especially when metal is missing or an original finish has deteriorated, so a responsible professional will describe realistic outcomes rather than make absolute promises.

Specialist work and external craftspeople

Some restoration requires specialist skills, such as hand engraving, stone cutting, enamel repair, pearl restringing, watch servicing or work on historically significant jewellery. Using an external craftsperson is not necessarily a concern. What matters is that the jeweller explains who will carry out the work, why that expertise is appropriate, how the piece will be transported and stored, and who remains accountable for the completed restoration.

For valuable or particularly important jewellery, ask whether an independent valuation is advisable before work starts. A valuation can help document the item for insurance and may identify features that should be preserved. It should not be confused with a repair estimate: a valuation assesses financial value, while the restoration assessment determines condition and required work.

Confirm the completion checks and aftercare

When the restoration is complete, the jewellery should be inspected for secure settings, sound joins, correctly functioning catches or hinges, smooth edges and an appropriate finish. Ask what aftercare is recommended and whether the work is covered by a written guarantee or warranty. The terms should explain what is covered, for how long and whether future wear, accidental damage or further deterioration is excluded.

At Steven Charles Quance, the appropriate restoration approach depends on the jewellery’s construction, condition, materials and intended use. A careful consultation allows these factors to be considered before work is agreed. If you are unsure about a previous repair, the condition of a treasured piece or the qualifications relevant to a proposed restoration, arrange an assessment before authorising any irreversible work.
