Why Buy Pre-owned Jewelry

There are 2 key benefits to buying second-hand jewellery:

  • Best Prices: Get up to 80% off retail prices by shopping pre-owned jewellery.
  • Eco-friendly: Buying pre-owned is the most sustainable and eco-friendly way to shop. Second-hand jewellery does not contribute to environmentally damaging metal and gemstone mining practices. And unlike lab grown diamonds which require huge amounts of energy to produce a single carat, second-hand diamonds are already in circulation. By shopping recycled jewellery, you are making an environmentally responsible purchase.
