How sustainable is your jewellery?

OERUM is a completely sustainable fine jewellery brand. All our jewellery is ethically made using recycled 18k solid gold. But it does not stop there – sustainability is the golden thread in all that we do; from our designs and packaging, down to our production methods and overall operations. And in case that wasn’t enough, we are also partnered with ‘Trees for All’, meaning that for every EUR 250 spent in our store, we plant a tree to give back to our community and reduce our environmental footprint.

What’s the difference between 14k & 18k gold?

The carat grading of gold refers to the percentage of pure gold in the alloy. 14k gold contains 58.3% pure gold whereas 18k gold contains 75% pure gold. Both are mixed with other alloys to make the jewellery piece more durable. To learn more about the materials we use please see our blog post here which explains this in more detail.

Diamonds

We do not currently use diamonds in our jewellery however, OERUM is committed to using responsibly sourced materials and providing complete transparency to our customers, to which the origin of our diamonds is a very important part of that commitment.
