Hallmarking


You will have seen that all of our jewellery is made from Sterling Silver. But what exactly does this mean? To be branded as such, a piece must contain 92.5% pure silver and 7.5% of another metal, which means Sterling Silver is known as an alloy. Pure silver is a very soft metal, and if we made our jewellery out of it, it would quickly lose its shape. So a different metal is added to the silver to increase its durability, without reducing the beautiful look.

Our designers only use the highest quality 925 Sterling Silver (remember 925 = 92.5% silver), backed up by our British Hallmark – a small mark stamped into the jewellery to guarantee quality. Our Hallmark is normally stamped with these elements:

  • Our company hallmark HH or Hiho which is in a hexagon shaped box
  • 925 in an oval – this indicates that it is sterling silver and imported
  • Anchor or other symbol indicating the place of assay.
  • Date Letter - this changes each year and for 2020 it is I and for 2021 it will be W

To read more about the hallmarks please go to: www.theassayoffice.com/help-with-hallmarks/compulsory-marks

To ensure the quality of all our pieces, the British Hallmark is applied to all our pieces above the legal weight threshold of 7.78 grams of silver. We also qualified for the assay assured scheme, an independent Hallmark verification operated by the Assay Office, and we have joined the National Jewellery Association.


New Platinum Jubilee Commemorative Mark - available from 1st November

A new commemorative mark has been designed to celebrate Her Majesty The Queen’s Platinum Jubilee - available from 1st November 2021.

In 2022, Her Majesty The Queen will become the first British Monarch to celebrate a Platinum Jubilee, seventy years of service, having acceded to the throne in 1952. To celebrate the occasion, the body which oversees UK hallmarking, the British Hallmarking Council, has sanctioned a commemorative component mark.

Designed by Thomas Fattorini Ltd, the mark depicts an orb, and can be applied to our new pieces. Jewellery is considered a treasured heirloom, and may be handed down through the generations; those items carrying the Platinum Jubilee Mark may become collectable, and feature as a talking point in years to come.


It can also be added to your existing Hiho jewellery for an additional charge. Please contact our Countess of Contentment on 01460 221006 or email contact@hihosilver.co.uk if you are interested in the new Hallmark. 


Rainbow Logo Mark - Raising Funds for the NHS


At the beginning of the covid pandemic in 2020, rainbows started to appear in the windows of homes all over the UK spreading hope amid the COVID-19 pandemic.  The Rainbow logo mark depicts the iconic Rainbow symbol that has become synonymous during the current pandemic. From June 2020 and until December 2020, all Hiho jewellery over  7.78 grams of Silver has been lasered with this iconic Rainbow Logo mark in addition to the hallmarks that we usually have. 

For each Rainbow Hallmark that was applied to our pieces, the assay office donated 100% of our hallmark costs to the NHS. Keep an eye out for this on some of our jewellery as you may have been lucky enough to get a piece with the rainbow on.  






However, no matter how good quality our silver is, it does still need some looking after, as it is still a precious metal which can become scratched without the proper care and attention. Why not pick up one of our polishing cloths to help keep your silver in tip top condition and have a read of our 'Looking after your Jewellery' page, which will give you good tips of how to look after your pieces.

The problem of scratched silver is one that we were keen to address, and saw the introduction of our leather and stainless steel pieces. Leather has been around for millions of years and has stood the test of time as a durable and beautiful material to work with. Teaming it up with the silver-like stainless steel produces an incredibly durable piece that can be used for all occasions from Graduation to Mucking out!
