The Jewellery Boutique

As a mark of authenticity and a guarantee of quality, all jewellery is hallmarked in accordance with current legislation. Each item is tested before being stamped with a makers mark and a fineness mark at The London Assay Office


In the manufacture of jewellery, precious metals are not used in their purest forms and instead are alloyed with other metals.

Hallmarking refers to the independent verification of  the precious metal content.

The hallmark is only applied after the item has been assayed to determine that its purity conforms with what it has been described as

The hallmarking allows customers to identify the precious metal make-up of a jewellery piece. It is not possible to discern by sight of touch alone what the precious metal of an alloy is, and so the hallmark acts as your guide to the content of the piece.

The Jewellery Boutique works with all precious metals which includes sterling silver, yellow gold, white gold, rose gold, palladium and platinum. 

Articles below a certain weight are exempt from hallmarking. The exemption weight is based on the precious metal content only, excluding, for example, weight of diamonds, stones etc, except in the case of articles consisting of precious metal and base metal in which case the exemption weight is based on the total metal weight:

Platinum 0.5 grams

Gold 1.0 gram

Palladium 1.0 gram

Silver 7.78 grams


Articles below these exemption weights may be described as Gold, Silver, Palladium or Platinum without the need for a hallmark.
