585 white gold consists of 58.5% pure gold, while 750 white gold contains 75% pure gold. The difference lies both in the proportion of gold and in the properties of the alloys. 585 white gold offers an excellent balance between durability and beauty, as it is more robust due to the higher proportion of other metals and is well suited for everyday use. 750 white gold, on the other hand, has a more intense color and higher value as it contains more pure gold, but is slightly softer and less durable. Both variants offer elegance, with 585 white gold impressing with its durability, while 750 white gold has a more luxurious appearance.
