Engagement ring online shopping tips for NZ buyers have never been more relevant. Walking into a jewellery store used to feel like the only way to make this purchase with any real confidence. That's no longer true. Online shopping has matured to the point where you can inspect a stone's inclusions in high-definition video, build a custom ring from your phone, and have it shipped express to your door, backed by a warranty.
At Nura Lab, we offer a guided Ring Builder, free customisation, and dedicated support that rivals any in-store visit. This guide covers everything NZ buyers need to know before committing: from setting a smart budget to verifying diamond certificates and getting the perfect fit remotely.
Setting a Realistic Budget
How lab grown diamonds have changed the game
Lab grown diamonds have shifted what's possible. In New Zealand, a 1-carat lab grown diamond typically sits around NZ$500 to NZ$600, significantly more accessible than mined equivalents. These are chemically, physically, and optically identical to mined diamonds. Learn more at our Lab Grown Diamond Education page.
Because of this, the old "three months' salary" rule no longer applies. For more detailed guidance, see our post on how much to spend on an engagement ring in NZ.
Where your money goes
A common rule is to allocate 60-70% of your budget to the stone and 30-40% to the setting. If you're looking for maximum brilliance on a budget, moissanite is a fantastic alternative. At Nura Lab, our custom rings start from approximately NZ$1,499, offering a handcrafted piece in solid gold.
How to Verify a Diamond Certificate
GIA vs. IGI
While GIA is the gold standard for natural diamonds, IGI (International Gemological Institute) is the industry standard for lab grown stones. IGI reports provide crucial details like growth method (CVD or HPHT). For a breakdown of these labs, see this GIA vs IGI comparison.
Prioritising the 4Cs
Cut is king. It controls the "sparkle." You can often trade down slightly on Color (to G or H) and Clarity (to VS2 or SI1) to prioritise an Excellent Cut without any visible difference to the naked eye.
Getting Ring Sizing Right Remotely
- Physical Sizers: The most accurate way is to have a sizer mailed to you.
- Existing Rings: Measure the inner diameter of a ring that already fits well.
- The "Two-Time" Rule: Measure your finger at different times of day, as size fluctuates with temperature.

Green Flags vs. Red Flags
Green Flags (Trust These Jewellers)
- Independent certification on every stone.
- High-resolution 360-degree videos of the actual diamonds.
- Transparent aftercare (resize policies, long-term warranties).
- Clear GST and customs handling for New Zealand buyers.
Red Flags (Walk Away)
- "In-house" certificates that aren't externally verifiable.
- No clear return policy or "all sales final" on standard items.
- Only using stock photos and no actual product videos.
- Evasive or slow customer support responses.
Your Rights in New Zealand
Under the Consumer Guarantees Act 1993, your ring must be of acceptable quality and fit for purpose. These rights exist regardless of a retailer's warranty. For more info, visit the Commerce Commission’s guide to buying online.
