Choosing the right metal

Choosing the right metal

A question we get asked often is "what is the right metal for me?" This is all down to a few things, your personal choice, if you have allergies to certain alloys and how hard wearing you require you jewellery to be. This applies for all jewellery types such as engagement rings, wedding rings, pendants, earrings and even cufflinks.

For example - for a ladies wedding ring we would recommend for you to go for the same metal as the engagement ring as this will allow the two metals to wear at the same pace and would be of the same durability. However if you have a platinum engagement ring and did not want to pay the price again for a platinum wedding ring then you can have a palladium wedding ring as these two metals will have the same wearability. (This will be explained below).

What Metal?


Pure gold (24ct) is too soft to be used on its own in jewellery. It is alloyed with other metals to give it strength and durability. The higher the pure gold content, the higher the number of carats. Here at G H Moore, we use 9ct and 18ct gold.

In 9ct gold, 375 parts out of 1000 are pure gold.

In 18ct gold, 750 parts out of 1000 are pure gold.

Pure gold is naturally a very bright yellow but it can be mixed with different metals to give us yellow gold, white gold and rose gold. 

Yellow Gold

9ct yellow gold is a slightly paler yellow colour to 18ct yellow gold which is a richer colour. We use both 9ct gold and 18ct yellow gold in our jewellery.

White Gold

White gold is pure yellow gold that has been mixed with different alloys to promote a whiter colour, these alloys can be silver and palladium. The natural colour of white gold will still have a slightly yellowish tint, most white gold jewellery is rhodium plated which give it the appearance of a bright white metal such as platinum or palladium, unfortunately this will wear off over time taking the ring back to its natural colour. This can easily be corrected with a re-polish and re-rhodium plating. We use both 9ct and 18ct white gold in our jewellery.

Rose Gold

Rose gold is gold mixed with copper giving it a lovely pinky colour. We use both 9ct and 18ct rose gold in our jewellery.


Platinum is a naturally bright white metal. It will not discolour unlike white gold. Platinum is a very durable metal making it very hard wearing, although it will still scratch and can lose its shine, but this is easily removed with a re-polish. The Platinum that we use in our jewellery is 95% pure and is only mixed with 5% other alloys, this gives it a fineness mark of 950. Platinum is naturally hypoallergenic.


Palladium is a very similar metal to platinum as it also a naturally bright white metal and will not discolour. Palladium is less dense in weight making it lighter on the finger which some people find more comfortable. The palladium we use for our jewellery is 95% pure which gives it a fineness mark of 950. Palladium is naturally hypoallergenic.

For the manufacture of jewellery and silverware, precious metals are not used in their purest forms. Instead they are alloyed with other metals.  It is not possible to discern by sight or by touch what the precious metal content of an alloy is.

Our customers can rest assured that all of our products come with a guarantee of the precious metal content through the 700-year-old practice of third party independent hallmarking.

The 1973 Hallmarking Act makes it unlawful to describe an item over a certain weight as gold, silver, platinum or palladium without an independently applied Hallmark.

  • All Silver articles weighing more than 7.78 grams must be hallmarked.
  • All Gold articles weighing more than 1 gram must be hallmarked.
  • All Platinum articles weighing more than 0.5 grams must be hallmarked.
  • All Palladium articles weighing more than 1 gram must be hallmarked.

Articles below these exemption weights may be described as Gold, Silver, Palladium or Platinum without the need for a hallmark.
