I love the organic, funky nature of this Judith Bright Labradorite Ring ($195). It would be the perfect complement to a no-fuss outfit, but since it's not a diamond, this rock costs a lot more than what I would like to pay.
To see the look for less,
This Old Navy Wrapped-Stone Ring ($5) is practically the spitting image of the one above, minus the labradorite stone, but who will know the difference? No regrets with this super cheap find.
