We do however have our head office in Pukekohe where we are happy to meet with you for consultations. We offer free shipping on all items and a 30-day money back guarantee (please see the returns sections below) if in the unlikely event you are unhappy with your purchase.

Our general office hours are Monday to Friday, 9.00am- 4.30pm. You are more than welcome to call us during this time on 0800 88 88 37 or email us at any time at info@diamonds.co.nz. Alternatively, join a live chat or leave us a message on our website or Facebook instant message with one of our diamond experts.. 

3. Can I book a consultation with a diamond expert?

4. How can I trust you?

Paul, our Managing Director here at diamonds.co.nz, has been selling diamonds within the New Zealand jewellery industry for more than 30 years.

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

Of course. Any diamond on our website can be purchased as a loose stone. 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.

3. Do the diamonds you sell come with reports?

All diamonds we sell on diamonds.co.nz come with GIA, IGI or HRD reports. Most of the diamonds also have laser inscriptions on the girdle of the diamond and this is used to verify the diamond with the diamond report.

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 up with the diamond report that comes with your purchase validating that the diamond is indeed the same as the one purchased. As diamond graders, we also quality control the diamond to ensure it is the corresponding 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 to a minimum 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.
