Lab made diamonds are diamonds created in a laboratory rather than mined from the earth. They have the same physical and chemical properties as natural diamonds. If you look at a lab made diamond under a microscope or test it with a diamond tester, you cannot tell the difference from a mined diamond.
These diamonds are grown using controlled conditions. The two main methods are High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). HPHT mimics the natural conditions deep within the earth, while CVD uses gas to deposit layers of carbon that form a diamond crystal.
For buyers in New Zealand, lab made diamonds offer an alternative to mined diamonds. They are often more affordable and can be produced in a way that reduces environmental and ethical concerns. If you are considering a diamond necklace NZ, understanding lab made diamonds can help you choose a piece that fits your values and budget.

Why Consider Lab Made Diamonds
Choosing a lab made diamond has practical advantages.
- Cost: Lab made diamonds usually cost 20 to 40 percent less than mined diamonds of the same size and quality.
- Clarity and Color: Since the growth process is controlled, you can get higher clarity diamonds or diamonds in unique colors.
- Ethics: Lab made diamonds avoid issues associated with conflict diamonds and exploitative mining practices.
- Environmental Impact: Mining diamonds requires large amounts of land and energy. Lab grown diamonds have a smaller ecological footprint.
For someone looking for a diamond necklace NZ, these advantages can make a big difference. You can choose a larger or higher-quality stone while staying within budget.
How to Evaluate Lab Made Diamonds
The four Cs apply to lab made diamonds just as they do for natural diamonds: Carat, Cut, Color, and Clarity. Understanding these will help you compare options and get the best value.
- Carat: This measures the weight, not the size. Two diamonds of the same carat can look different depending on cut.
- Cut: Cut affects how a diamond reflects light. A well-cut diamond will sparkle more even if it is smaller.
- Color: Lab made diamonds can range from colorless to faint yellow or brown. Some labs can even produce fancy colors like blue or pink.
- Clarity: Fewer internal flaws make a diamond clearer. Lab diamonds can often be produced with fewer imperfections than mined diamonds.
When buying a diamond necklace NZ, request certification for the stone. Reputable labs provide a grading report from GIA, IGI, or AGS that confirms quality.
Buying Lab Made Diamonds in New Zealand
The market for lab made diamonds in New Zealand is growing. Local jewelers and online retailers offer options for both engagement pieces and fashion jewelry.
Here are steps to take:
- Research reputable sellers: Look for jewelers who provide certification and transparent information about the diamond’s origin.
- Compare prices: Lab made diamonds are cheaper, but prices vary based on cut, carat, and color.
- Inspect the diamond: If possible, view it in person to check sparkle and finish.
- Ask about settings: A diamond necklace NZ may have different chain options or metal types, affecting durability and style.
Example: A 0.5-carat lab made diamond pendant may cost around half the price of a natural diamond pendant of the same size. You could invest the savings in a higher quality chain or design.
Maintaining Your Lab Made Diamond Jewelry
Lab made diamonds are as hard as natural diamonds, so they resist scratches and damage. However, the setting and chain material need care.
- Clean regularly: Use warm water and mild soap, then dry with a soft cloth.
- Store safely: Keep necklaces separate to avoid tangling and scratches.
- Check settings: Periodically ensure prongs and clasps are secure.
A well-maintained lab made diamond necklace NZ can last decades and retain its value.
Common Misconceptions About Lab Made Diamonds
Many people assume lab made diamonds are fake. This is not true. They are real diamonds with identical chemical and optical properties.
Other misconceptions include:
- They are lower quality: Lab diamonds can match or exceed mined diamonds in clarity and color.
- They are less durable: Diamond hardness is the same whether lab grown or mined.
- They lose value quickly: While resale markets are different, the intrinsic quality remains high.
Understanding these facts helps buyers make confident choices for a diamond necklace NZ or other jewelry.
