A Guide to Precious Metals… Which should you choose?

  • First and foremost remember it is about personal preference – in our opinion this is the most important factor as it will be unique to every person.
  • The hallmark for 18ct gold is 750
  • The hallmark for 9ct gold is 375
  • The hallmark for platinum is 950
  • White gold whether 9ct or 18ct has a natural yellow pigment to the metal. To combat this, white gold is always rhodium plated to give the same appearance as platinum. However, over time this plating wears off and will need re-applying. A great alternative is to opt for platinum instead as this precious metal does not need plating and so will stand the test of time.
  • Platinum is generally deemed a far more expensive material, however currently this is not the case – which makes it a very affordable option as well as being the superior choice.
  • There is a slight colour difference between 9ct and 18ct golds. 9ct gold contains less pure gold than 18ct therefore the intensity of colour is less – hence the difference in cost, too.
  • The Birmingham Assay Office Hallmarking Chart has a wealth of in depth information on precious metal hallmarks.
  • Some coloured gemstones complement certain precious metals. For example, a blue sapphire works very well with platinum because the blue has cool hues. Contact us for more information.

  • It is a popular choice for engagement rings and wedding rings, however bare in mind the rhodium plating mentioned above.
