9ct / 18ct White Gold
White gold has a similar appearance to platinum which makes it another great choice for jewellery. White gold is often rhodium plated, providing a brighter finish, however this may not be suitable for people with a nickel allergy. Non-plated 18ct or 9ct white gold varies slightly in colour due to variable gold content, with 9ct appearing whiter and brighter.
Non-plated 18ct white gold, although more precious, is softer than 9ct white gold, due to the higher gold content (75%). 9ct white gold is more durable. Rhodium plated white gold rings need to be re-plated every one to two years, to maintain their colour.
White gold is more affordable than platinum. It does however require more maintenance, so may involve more costs longer term.
