What Is Pure Gold?

Here at Juliet & Oliver, we use only the highest-grade materials to produce our Hypoallergenic nickel free jewelry. While nickel might be contained in the white gold, we also use rose gold, yellow gold and other non-nickel contained metals that are manufactured in a nickel free environment, so you can always find the ring that is not only beautiful but also doesn’t cause any discomfort to you or any environmental pollution.

Heavy Metals harm Your Body!

Juliet&Oliver wishes to make nickel free engagement rings and nickel free wedding rings available for wear even to those with skin sensitive to nickel.
