What makes a lab grown diamond necklace different?
The primary difference between natural diamonds and lab grown diamonds is the origin of the stone. Natural diamonds are formed deep in the earth. Whereas laboratory diamonds are grown in a controlled environment using specialist equipment.
They have the same chemical make-up, crystalline structure and optical properties so are genuine diamonds and not fake diamonds like cubic zirconia.
The two most common methods of creating lab grown diamonds are Chemical Vapour Deposition (CVD) and High Pressure High Temperature (HPHT). Both produce diamond crystals that can be cut and polished into jewellery.
A great name to know about if you’re looking to compare lab grown diamond jewellery in Spain is Novita Diamonds at novitadiamonds.es
Types Of Necklaces
You don’t always need a large centre stone on a diamond necklace. The shape and positioning can affect how it looks.
Solitaire
This style of necklace will have one diamond, usually set into a prong or bezel setting. Round brilliant stones are a popular choice as they have lots of facets to reflect light from different directions.
A bezel setting will have a thin ring of metal surrounding the stone giving a smooth finish to the necklace.
Halo & Multi Stone
This style of necklace will have smaller stones surrounding the centre stone. This helps to widen the outline and adds more sparkle.
Other styles will have the diamonds in a straight line, curved pattern or cluster. This is ideal for those looking for more detail but don’t want a heavy necklace.
Tennis
This style of necklace will have a full row of diamonds. Unlike a pendant this will spread the sparkle across your neckline.
The chain links should be flexible with a secure clasp. The stones will be evenly spaced. A well made necklace should be comfortable and not twist.
Quality Of Diamonds
When comparing lab grown diamond necklaces there are various factors to consider.
The cut of the diamond will determine how much light it reflects. The colour will tell you how much colour is present in the stone. Clarity refers to the characteristics inside and on the surface of the diamond.
A smaller stone with good proportions may look nicer than a larger stone with poor cuts.
Independent documentation can help you know exactly what you’re getting. Organisations like the International Gemological Institute (IGI) provide reports on lab grown diamonds.
GIA also updated the language used to describe lab grown diamonds in 2025. It’s important to know what system the seller is using.
Gold & Chain Length
The metal will greatly affect how your necklace looks.
Yellow gold will give a warm contrast with the colourless diamonds. White gold will give a cooler look and Rose gold will give a softer pink look.
If you’re buying in Spain you may see 18 Karat gold which is marked as 750 and 14 Karat which is marked as 585. This shows how much of the gold is pure.
Chain Length:
40cm – Usually sits lower on your neck.
45cm – A versatile option for most everyday pendants.
50cm – Allows the pendant to hang lower on your chest.
The exact placement will depend on how big your neck is and the style of the necklace.
Things To Consider When Buying Online
It can be difficult to see how large the pendant is by looking at pictures. It’s important to look at the measurements.
Look at how large the diamond is in millimeters. Check how thick the chain is, what kind of clasp it has and how free moving the pendant is.
If you’re buying in Spain make sure to compare the price in Euros. Make sure the taxes and delivery are clearly shown.
Novita Diamonds can be compared but it’s important to look at the specifications, documentation and current returns policy.
Check if the necklace comes with a grading report or any documentation to confirm it’s a lab grown diamond.
Caring For Your Diamond Necklace
Lab diamonds are hard but the settings and chains should be cared for.
Perfumes, lotions and general grime can collect around the pendant. Often you can clean gently using warm water, mild soap and a soft brush. This will depend on the metal and setting.
Store separately to avoid tangles and scratches. Occasionally check the clasp and setting.
It should be comfortable, hang where you want it to and match the clothes you’re wearing. Often the small details will be more important than the largest diamond.
