Product Information

Petra’s work is handmade in the UK. Petra uses precious metals and non-precious materials in her collections.

All silver used is sterling or fine silver, the gold is 18ct and all are subject to British hallmarking standards at the London Assay office.

Where gold plating or gold vermeil is used the pieces are hallmarked as silver.

Where non-metal materials eg nylon are used the items are still subject to hallmarking with the appropriate metal mark.

Some items are too lightweight to require hallmarking by the Assay office. These items are legally sold as silver or gold.

Where items are stated to be made of un-hallmarked metal(s) these items include metal(s) that are non-precious rendering the whole piece to be un-hallmarked.

Ring orders: to ensure you order the correct sized ring Petra would recommend you come to her to be measured, however if you are unable to visit her workshop then you will need to be sized at a reputable jewellers.

All work is bespoke and stated dimensions may vary slightly.
