We offer a sizing service for most rings, whether they are silver, 9ct gold, 18ct gold, platinum or palladium, including a re-rhodium for white gold rings.

We can size plain, patterned and stone set rings; all will be examined to asses the full extent of works required and a rough estimate of price can normally be given when leaving the ring. No work will be carried out without a confirmed price.

Ring sizing takes between 1-2 weeks for completion, depending on whether the work is carried out in-house or sent away to our workshop.

Palladium is in the same group of metals as platinum, with the similar properties. Palladium is not as dense as platinum, meaning it weighs less, which can sometimes appeal to people.

 

Hallmarking Act 1973

Nowhere else in the world are consumers more highly protected than in the UK. The UK is one of only a few countries in the world that have compulsory statutory hallmarking. This means that every item sold as precious metal, ie gold, silver, platinum or palladium must have been tested and hallmarked by an independent third-party Assay Office to guarantee that the precious metal is of the fineness stated.

The law applies to everything SOLD in the UK , regardless of where it may have been manufactured.  The only exemptions are items which fall beneath the specified weight thresholds which are 1 gram for gold, 7.78 grams for silver, 0.5 grams for platinum and 1 gram for palladium.
