When it comes to manufacturing jewellery, precious metals such as gold, platinum or palladium are rarely used in their purest form. To increase their strength and enhance colour, they often need to be alloyed with a choice of metals.
As it is impossible to detect the nature of the alloy by sight alone, we have our gold, platinum and palladium jewellery independently tested and hallmarked before they are sold. All our fine jewellery items bear a hallmark at point of sale, with the following weight exemptions:
Gold and palladium: non-mandatory for items below 1 gram.
Platinum: non-mandatory for items below 0.5 grams.
77 Diamonds is registered with the London and Birmingham Assay Offices, ensuring our jewellery is compliant with the UK’s hallmarking regulations. All stock is subject to an internal confirmation process to ensure it meets the UK’s hallmarking regulations before it is dispatched to our customers.
We are an Assay Assured Jewellery Retailer. Assay Assured status is only given to retailers who have been independently audited and verified by Assay Assured which is run and overseen by the Edinburgh Assay Office, ensuring all precious metal jewellery are independently tested and hallmarked.
All our jewellery is hallmarked in the United Kingdom. You will view the following hallmarks for each metal:
Gold (Rose, White and Yellow) – 750
Platinum and Palladium – 950
