(or is it!)
When you look in the jewellers showcase at white gold 99% of
what you see has been rhodium plated.
The rhodium will wear away on rings quite quickly leaving them a rather
dull cream/brown colour.
Garden Workshop only uses a high white gold for all of its white gold jewellery.
The gold has been alloyed with 13% palladium to give a white gold that
needs no plating and will always look white.
