Free shipping on all website orders within Australia.

At LeGassick, we offer free, fast, secure shipping within Australia for any LeGassick website purchase. All items are beautifully boxed and ribboned, just as if they were purchased at one of our LeGassick Showrooms.

We will supply you with a shipping code so you can track your beautiful jewellery on its journey.

We will resize your ring at no charge to ensure the fit is correct.

The complimentary resize is within the first 30 days of purchase, and not after the ring has been worn for a period of time. This applies to any ring purchased online through our LeGassick website.

Some rings may not be able to be resized due to the design style. If your LeGassick ring is unable to be resized, we will work with you to re-make your ring in the finger size required at no extra charge (terms and conditions apply). This process can take up to 4 weeks. LeGassick will discuss with you directly the process, keep you informed with updates, and ensure your ring is back where it belongs as quickly as possible.
