Why get a valuation?
Most insurers ask for a current valuation before they cover a piece, and use it to replace like with like after a loss. Without one, a claim can be settled for less than it would cost to replace the piece.
How often should jewellery be revalued?
Every two to three years, or sooner if gold or diamond prices move sharply. An out-of-date valuation can leave a piece under-insured or over-insured.
What makes a valuer qualified?
In Australia, look for a valuer registered with a professional body such as the National Council of Jewellery Valuers. A registered valuer follows set standards and is independent of the sale.

Does CTJ buy or trade in diamonds?
No. We don’t offer buy-back or trade-in. A valuation for insurance is not a resale offer, and resale prices sit well below replacement value.
