our policies

We are an Australian owned and operated website and our philosophy is to always make the customer happy. We will make every endeavour to do so within and beyond the guidelines of the Australian Competition and Consumer Commission and Australian Consumer Law.

These guidelines are available at the following sites:



Nina's are also guided by the standards of the the Jeweller's Association of Australia. Established in 1931, the Jewellers Association of Australia (JAA) promotes the highest standards and ethics within the Australian jewellery industry and encourages consumers to shop with confidence where they see the JAA member sign.

Diamond Policy

All of our diamonds are natural stones, sourced wherever possible from Australia. We do not use artificial or created diamonds. All of our diamonds are 100% conflict free.

Free Resize Terms & Conditions

Customers are entitled to (1) free resize with the purchase of any full-price ring. The resize must be redeemed within 30 days of purchase. If the product must be returned via post to Nina's Jewellery for adjustment, the customer is responsible for shipping costs one way, and Nina's Jewellery will provide complimentary shipping to return the item. Products shipped back to Nina's Jewellery correctly packaged and addressed will be fully insured by Nina's Insurance.

To arrange to have your ring resized, please contact us first via LiveChat, email, or 1800 878 997.


Nina's Jewellery is happy to assist you with confirming the required size for your ring, however, once the size is confirmed and the ring adjusted, Nina's Jewellery is not responsible for any customer error or change of mind. Any additional resizes as a result of either of these situations will be at the customer's cost. 


Resizing services are not available on sale rings. Sale rings are available in floor stock sizes N/O only.

Warranty & promise of service

Every piece of Nina's Jewellery is crafted to pass our strict quality assessment measures, and is unique, just like their wearers.

As such, each piece is subject to unique conditions based on its composition and its wearer.

Nina's jewellery is made to be worn, but we understand that this comes with inevitable wear and tear. Nina's does not offer a warranty on our products, rather, we treat each product on a case-by-case basis due to the one-of-a-kind creation that it is. We instead offer a promise of service. This means that at any time, if you experience a problem with your Nina's piece, whether from wear and tear, insurance, damage or manufacturing fault, our team of GIA-certified Diamond and Design specialists and Master Jewellers are committed to assessing the item, and assisting to the best of our ability. 

Please note that pieces that have been worked on by other jewellers void the promise of service, as we cannot account for work that does not take place in our own workshop.

Full-price jewellery pieces and some loose stones are accepted for credit or exchange if returned to Nina's in their original purchase condition (subject to assessment) accompanied by all original documentation (including sales receipt) within 30 days of the purchase date, or within 30 days of shipping.

If you should find a major problem with a Nina’s product, you can ask for a replacement or refund.

The definition of a major problem is when:

  • it has a problem that would have stopped someone from buying it if they’d known about it
  • it is unsafe
  • it is significantly different from the sample or description
  • it doesn’t do what we said it would, or what you asked for and can’t easily be fixed.

If you should find a major problem with a Nina’s product, you can ask for a replacement, repair or refund.

A replacement product will be as close to the product originally supplied as possible.

Refunds will be the same amount you have already paid, provided in the same form as your original payment.

Nina’s has the discretion to take into account how much time has passed since you bought the product.

Nina's reserves the right to repair the original item in the event that evaluation by their Master Jeweller deems the fault to be superficial. 

Nina's Jewellery is not responsible for damage or issues resulting from wear and tear.

If you suspect your piece is faulty, please contact customer service via phone, email or chat, or call in to store. A representative will be available from 9am-5pm Monday-Friday WST.
