Lab Grown Diamonds in New Zealand: The Complete Buying Guide

Lab grown diamonds have become the first choice for many New Zealanders buying engagement rings, earrings and everyday fine jewellery. This guide walks you through every decision, from the diamond itself to the gold it is set in, so you can buy lab grown diamonds in NZ with confidence.

Step 1: Understand the 4Cs

  • Cut: how well the diamond is shaped and faceted. It has the biggest effect on sparkle.
  • Colour: graded from D (colourless) down the alphabet. Our diamonds are E–F, in the colourless range.
  • Clarity: how free the stone is from inclusions. Our diamonds are VVS–VS, with inclusions invisible to the eye.
  • Carat: the weight of the diamond, and the C most people notice first.

Step 2: Insist on a certificate

A grading report from an independent laboratory confirms the diamond's 4Cs and that it is lab grown. KlōT͟HiNG uses IGI-certified lab grown diamonds. See What IGI Certification Means.

Step 3: Choose your shape

Round brilliants give maximum sparkle; ovals, pears and marquise shapes look larger for their carat weight and lengthen the finger. Explore every shape in Diamond Shapes Explained.

Step 4: Choose the metal

Solid 14K gold balances richness of colour with everyday strength, which is why every KlōT͟HiNG piece is set in solid 14K gold rather than plated metal.

Step 5: Pick the right piece

Step 6: Understand the price

Lab grown diamonds usually cost a fraction of mined diamonds of the same size and grade. When comparing prices in New Zealand, check whether GST and shipping are included. At KlōT͟HiNG, the NZD price you see includes GST. For the bigger picture, read Diamond Prices in 2026: The Honest Truth About Value.

Step 7: Look after it

Clean with warm water, a drop of mild soap and a soft brush, and store pieces separately to avoid scratches. Full guide: How to Care for Your Diamond Jewellery.
