I am not sure which has made me more chuffed. 

To write my first prescription or get my own hallmark /sponsor mark. 

My first choice being Silverball was three circles conjoined,  but someone else had that darn. So this  is my mark,  for posterity,  

Silverball jewellery (SBJ) with a Birmingham assay office mark which is an anchor and for all pieces done this year as special assay mark for the platinum jubilee.


Any article described as being wholly or partly made of gold, silver, platinum or palladium that is not covered under exempt articles.

Main Exemptions:
Articles below a certain weight are exempt from hallmarking. The exemption weight is based on the weight of the precious metal in the article, excluding, for example, 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:
• Silver 7.78 grams

• Palladium 1.0 gram

• Gold 1.0 gram

• Platinum 0.5 grams

Any pre-1950 item may now be described and sold as precious metal without a hallmark, if the seller can prove that it is of minimum fineness and was manufactured before 1950.
