Lab-Grown Diamond Pendants: What Buyers Should Check

Lab-grown diamond pendants give buyers a way to choose real diamond jewellery while having more flexibility around stone size, shape, setting style, and budget. For Australian shoppers comparing lab grown diamonds pendants, the most useful approach is to look beyond carat weight and focus on the diamond itself, the setting, the precious metal, and the information supplied by the retailer.

A pendant may appear simple, but its overall look depends on several details working together. Diamond cut can influence brilliance, the setting can affect how much light reaches the stone, and chain length changes where the pendant sits when worn. Understanding these factors helps buyers compare pieces more accurately.

Are Lab-Grown Diamonds in Pendants Real Diamonds?

Yes. Lab created diamonds are diamonds that are formed in laboratory conditions and not underground.

They have the same carbon crystal structure as diamond and have similar physical, chemical and optical properties to mined diamonds. They should not be confused with other materials which imitate diamond, such as cubic zirconia and moissanite, which are completely different minerals.

The main difference between lab grown diamonds and natural diamonds is that the former are formed in laboratories while the latter are formed in the ground.

This difference can sometimes only be identified using specialist equipment or at a grading laboratory. So when it comes to pendants, this means that buyers can use similar tests to determine the quality of laboratory created stones as they would a mined diamond jewellery.

Why Cut Matters So Much in a Diamond Pendant

Cut has a major influence on how a faceted diamond interacts with light. Good proportions and careful craftsmanship can improve brightness, sparkle, and the balance of light and dark areas seen across the stone.

The four main diamond quality factors are:

• Cut: how proportions and craftsmanship influence light performance.
• Colour: the degree of colour present or absent according to the grading system used.
• Clarity: the presence and visibility of internal inclusions and external blemishes.
• Carat weight: the diamond’s weight rather than its physical dimensions alone.

Two diamonds with the same carat weight can look noticeably different in size because shape, depth, proportions, and cutting style affect their visible spread.

For a pendant, cut can be particularly noticeable because the diamond is often viewed from the front without other large stones competing for attention.

Choosing a Diamond Shape for a Pendant

Though round brilliant diamonds remain a popular choice among customers due to their unique pattern of facets creating a strong brilliance, other shapes can be used to create a completely different character while retaining the basic jewellery purpose.

For instance, oval diamonds can be used to create elongated shapes, while pear-shaped diamonds can be used to create tapering jewellery pieces ideal for drop styles. Emerald cut diamonds, on the other, hand have larger flashes of light as compared to the smaller scintillation of brilliant cut diamonds.

Cushion, radiant, princess and marquise diamonds can be used to make pendants as well, based on the customer’s preference and the setting chosen.

No single shape is objectively better. Buyers lab created diamonds compare:

• visible dimensions
• length-to-width ratio
• facet pattern
• how inclusions appear
• how securely the stone can be set
• how the shape sits when suspended from a chain

A well-chosen shape should look balanced within the pendant rather than simply having the highest possible carat weight.

What Clarity and Colour Grades Are Practical?

Very high clarity is not always necessary for an attractive pendant.

Clarity grades describe inclusions and blemishes which would be seen under specified grading conditions, but some lower-grade diamonds may look clean to the naked eye, and some inclusions are likely to stand out more depending on their location, size, colour and the diamond’s facet pattern.

A diamond’s colour may also appear different depending on the setting, its shape and size.

In white gold or platinum, subtle body colour may be more noticeable in some diamonds, while yellow or rose gold may create a different visual relationship between metal and stone

Rather than looking for the maximum grade in each category, it is often more practical to find a suitable balance of cut, colour, clarity and weight.

Should a Lab-Grown Diamond Pendant Have a Grading Report?

A grading report can be useful because it provides independent information about the diamond’s characteristics.

Depending on the laboratory and stone, a report may include:

• carat weight
• measurements
• colour grade
• clarity grade
• polish
• symmetry
• fluorescence
• proportions
• laboratory-grown origin
• identifying features
• report number

Recognised laboratories such as IGI and GIA grade laboratory-grown diamonds, although report formats and terminology can differ.

A grading report should not be confused with an appraisal. Grading describes the characteristics based on the laboratory methodology and an appraisal could be providing a value for a different purpose. Neither should automatically be taken as a guarantee of future resale value.

If a report number or laser inscription is available, buyers can ask how it can be matched with the diamond they are buying.

Pendant Setting Style Can Change the Look

The setting can impact the appearance and functionality.

A prong setting exposes more of the diamond and can create a lighter, more open look in the design. A bezel offers greater coverage with a more smooth edge which could be preferred by some buyers. Halo designs use surrounding smaller stones to accentuate the overall shape of a central diamond.

The pendant’s bail, or the part that connects it to the chain, also plays an important role in the pendant’s ability to swing and hang.

Buyers that are shopping online for lab grown diamonds pendants at Novita Diamonds in Australia can evaluate these design considerations against the diamond specifications as opposed to a carat weight alone.

Choosing White Gold, Yellow Gold, Rose Gold or Platinum

Metal choice not only changes the appearance but the care required.

White gold offers a light-coloured option that looks beautiful with colourless or near-colourless diamonds, while yellow gold offers a contrasting look. Rose gold has a pinky hue, and platinum is another light-coloured metal favoured for fine jewellery.

Buyers should always confirm the exact metal specification (not rely on what they see in a photo), and should always ask if the chain and pendant are made of the same metal, and whether the listed carat weight is the centre diamond or total weight of all diamonds.

This is especially important for designs that use multiple stones.

How CVD and HPHT Diamonds Differ

Lab-grown diamonds can be formed by two methods, CVD or HPHT.

CVD stands for chemical vapour deposition and involves the formation of diamonds from carbon atoms within a chamber.

HPHT stands for high pressure high temperature and involves subjecting carbon to high pressure and high temperatures until it crystallizes into a diamond.

The method used to grow the diamond does not dictate the superiority of one type over the other. Both are naturally formed diamonds so it is important to look at the characteristics of the diamond and cut, color, clarity, proportion and grading if available.

Practical Checks Before Buying

Before buying a diamond pendant, ensure a clear understanding of what exactly one is purchasing.

Check the carat weight (individual or total) of the diamond(s), details on the precious-metal, chain length, type of clasp and whether or not the pendant comes with a chain, at all.

Review the return and service terms of the seller and ask them how the pendant should be cleaned. Although diamond can resist scratches better than most materials, jewellery settings and chains can and should be checked for signs of wearing at periodic intervals.

Keep grading reports, receipts and any other relevant paperwork in a secure place. These can come in handy when identifying the item and its specifications at a later date.
