Lab Grown Diamond Necklaces: Your NZ Buyer's Guide
A lab grown diamond necklace offers the same optical brilliance as a mined stone, the same hardness, and the same certification—at a price that makes fine jewellery feel realistic rather than aspirational. At Nura Lab, we’ve seen a significant shift: New Zealand buyers are choosing lab-created diamond pendants as a smarter, more ethical choice.
This guide covers the pendant styles worth considering, how to match chain lengths to your neckline, and realistic NZ pricing for every budget.
Popular Lab Grown Diamond Pendant Styles
Solitaire Pendants: The Everyday Essential
The solitaire pendant is the ultimate versatile piece. Whether you choose a prong setting to maximise brilliance or a bezel setting for a modern, protective edge, it’s a timeless staple. Consider an east-west orientation for a contemporary twist on the classic drop.
Tennis Necklaces: The Statement Piece
A continuous row of identically cut lab diamonds worn close to the collarbone. Thanks to lab-grown technology, these statement pieces are now accessible in the NZ$3,000–$5,500+ range—a fraction of the cost of mined equivalents.
Halo and Cluster Pendants
A halo adds a ring of smaller diamonds around a centre stone, creating the illusion of a much larger pendant. Cluster designs offer an organic, decorative look for those who want something beyond minimalism.
Diamond Quality in a Pendant
Cut is the most important factor. Because a pendant sits against your chest and catches the light from various angles, a high cut grade (Excellent or Very Good) is non-negotiable. You can be more flexible with Clarity (VS2-SI1) and Color (G-I), as these factors are less visible from a distance than they would be in a ring.
Always verify your stone via IGI or GIA certification. Never buy a diamond without a verifiable report number.
Chain Length and Metal Choice
- 16 inches (40 cm): Sits at the base of the throat; perfect for high necklines.
- 18 inches (46 cm): The "classic" placement; best for everyday wear and solitaire pendants.
- 20-22 inches (51-56 cm): Lower chest placement; ideal for V-necks and layering.

Why Solid Gold Matters
Unlike plated or vermeil jewellery, solid 14K or 18K gold will not wear through or lose its finish over time. Nura Lab uses exclusively solid gold to ensure your jewellery lasts a lifetime.
