Diamonds.co.nz does not operate in street level retail spaces. This ensures low overhead costs so we can focus on maintaining the best prices and the highest quality of product and service for our customers.

1. Can I buy diamonds only from diamonds.co.nz?

Yes absolutely. Any diamond on our website can be purchased loose. You will recieve a diamond presentation box with your order, as well as the corresponding diamond report. 

2. How do I know the diamonds you are using are ethical?

We purchase diamonds through companies that are Kimberley Process compliant which is a joint government, international diamond industry and civil society initiative to stem the flow of conflict diamonds. Diamonds.co.nz sources the vast majority of its diamonds from De Beers Diamond Trading Company Sightholders to ensure our diamonds have come through the correct channels. We are now supplying blockchain enabled diamonds via the Everledger Platform which gives the country of origin and original crystal weight.

3. Do the diamonds you sell come with reports?

All of our diamonds are sold with the original corresponding diamond report. Most of the diamonds also have the report number laser inscribed on the girdle of the diamond.

4. How can I make sure the diamond I ordered and the diamond I've received are the same?

The laser inscription on the diamond will match the corresponding diamond report that you receive with your purchase. As diamond graders, we also quality control each and every diamond.

5. Do you hold physical diamond stock within New Zealand?

Our website stock is virtual stock that is held offshore with our suppliers. This allows us to keep costs down and pass the savings on to our customers, offer diamonds that we wouldn't necessarily hold for the New Zealand market and meet your entire needs when it comes to purchasing a diamond or diamond jewellery. We do however have a selection of physical diamonds for viewing or immediate purchase in New Zealand.

6. What are the most important things to consider when purchasing a diamond?

It really comes down to personal preferences and budget. We recommend reading up about diamond education on our website and we are more than happy to advise you on what diamond we think would give you the best value for your money.

7. The diamond I am interested in has gone up or down in price since I last viewed it. Why would this be?

As diamonds are traded in USD, the New Zealand dollar prices can alter on a daily basis due to exchange rate fluctuations. 


1. I've ordered my ring online, how long does it take to make the item?

Your diamond is shipped from our supplier and the jewellery item is made in Auckland. From start to finish the process takes approximately 4-6 weeks, depending on the complexity of the design. We will contact you when your item has been shipped so you know when to expect it. 

2. What if I can't find the jewellery item I am looking for?

As well as our extensive range of jewellery settings listed on diamonds.co.nz, we also work with customers to create one-off jewellery as unique as you, using the lastest CAD (Computer Aided Design) Technology. So if you can't find what you are looking for on our website, we encourage you to use this service.

4. I've recieved my order but the ring size is incorrect, what do I do? 

Our customers receive one complimentary resize (a maxiumum of two sizes up or down) within 90 days of the order date. If it's outside these parameters, we will contact you with a quote to resize. If you wish to organise a resize, please contact your consultant directly or email info@diamonds.co.nz with your order number to arrange this.
