If you like how it looks, there are lots of advantages to rose gold:
Rose gold is more durable than other gold alloys, because of the copper content in it. This makes it more resistant to scratches and dents.
Rose gold has a unique look that’s perfect for engagement rings, with a soft, delicate look that tends to suit all skin tones.
It’s relatively easy to maintain as it doesn’t have any special coating that require extra care, unlike white gold which requires periodic rhodium plating.
Pretty much the only thing you’ll need to consider more carefully is whether your future bride-to-be will like this color – some people love it, others don’t.
