Diamond earrings can look simple at first glance, but small differences in diamond quality, matching, setting style and metal can noticeably change how a pair looks and wears.
For Australian buyers considering lab grown diamond earrings, the most useful approach is to compare the diamonds as a pair rather than judging each stone independently.
Earrings depend greatly on the visual balance of the jewelry. The matching of diameter, color, clarity and brilliance can be as relevant to the characteristics described on the grading report as the individual criteria specified.
Lab grown diamonds are real diamonds created in a controlled environment rather than occurring naturally. They have the same crystal structure and carbon composition as diamond and should not be confused with simulants such as cubic zirconia or moissanite.
What Makes a Good Pair of Lab-Grown Diamond Earrings?
A good pair should look balanced when worn, perform well under normal lighting and use settings appropriate for regular use.
For stud earrings, buyers should pay close attention to:
- diamond cut and light performance
- total carat weight versus carat weight per stone
- how closely the two diamonds match
- colour and clarity
- diamond diameter
- setting security
- precious-metal type
- backing style
Matching is especially important. Two diamonds may have the same reported carat weight but slightly different dimensions. If one stone has a noticeably larger face-up diameter, the pair can look uneven.
This is why diameter and proportions deserve attention alongside carat weight.
Cut Usually Matters More Than Very High Clarity
Cut will determine how well a diamond reflects light and, as a result, impact its overall brilliance and sparkle.
When shopping for earrings, you probably wouldn’t notice a difference between a VS1 and an SI1 unless you examined them side by side. The former will have a higher level of clarity than the latter, but unless the inclusions in the SI1 are readily visible to the naked eye, you likely wouldn’t notice much of a difference between the two diamonds. In this instance, I would recommend going with the VS1 since it will have a better light performance that will make the diamonds appear more lively and bright.
I think you should look at the colour of the mounting as well. White gold and platinum will bring out the diamond’s natural colour while yellow or rose gold will mute it slightly.
Ultimately the choice depends on what looks better to you rather than what the highest quality grade would dictate.
Understand Total Carat Weight Before Comparing Pairs
Carat measures diamond weight, not physical size.
With earrings, retailers may describe the combined weight of both diamonds as total carat weight. For example, a pair described by total weight does not necessarily contain two diamonds of that weight each.
Buyers should therefore confirm whether the stated figure refers to:
- one individual diamond
- both centre diamonds combined
- all diamonds in the earrings, including accent stones
Visual dimensions matter as well. Two diamonds at the same carat weight can face up differently depending on their shape, proportions and cut.
Comparing measurements can prevent misleading assumptions based on carat alone.
Should Diamond Earrings Come With a Grading Report?
Independent grading reports can provide useful information about diamond characteristics, particularly for larger stones.
A report may describe:
- carat weight
- colour
- clarity
- dimensions
- polish
- symmetry
- fluorescence
- laboratory-grown origin
- report number
- identifying features
Reputable labs such as IGI and GIA grade lab created diamonds according to their specifications.
A grading report should not be mistaken for an appraisal or a resale value. It provides information about the diamond, but it does not guarantee its subsequent value.
Single small diamond studs may not always come with grading papers because the cost and relative value of such a thing may not be justified in the same way as with bigger centerpieces.
Round, Oval and Other Shapes Wear Differently
Round brilliant diamonds are a popular choice for stud earrings due to their symmetrical outline, making matching easy, and the way that facets are arranged to maximise light return.
Other shapes create a different aesthetic when it comes to creating earrings.
Oval diamonds can give the illusion of length when worn whereas emerald cuts offer a more angular design created by faceting with large steps. Pear, cushion and princess shaped diamonds create distinct aesthetics.
Shape can influence:
- face-up appearance
- perceived size
- brilliance pattern
- how easily two stones can be matched
- the type of setting required
A shape should therefore be chosen for its visual character rather than because it is assumed to be universally better.
Choose a Setting for Security as Well as Appearance
The setting holds the diamond in place where it is worn, and this can influence how exposed the stone is.
Prong settings expose more of the diamond, and can create a lighter overall appearance, while bezel settings surround more of the diamonds edge, offering some additional protection (although creating a different visual presentation).
Earring backs are also an important consideration, with push backs being the most common, but some buyers may prefer screw backs for a different aesthetic.
Comfort should also be considered for pieces that are likely to be worn often.
The metal can also influence the presentation and upkeep of the piece, with platinum, white gold, yellow gold and rose gold being popular options. It is important that buyers are clear on the exact metal they require, rather than being deceived by images in marketing materials.
Lab-Grown and Natural Diamond Earrings Look Similar but Differ in Origin
Lab-grown and natural diamonds have similar physical, chemical and optical properties. The main difference is the way of formation. Natural diamonds are formed in the earth crust. Scientists use High Pressure High Temperature or Chemical Vapour Deposition methods for growing man-made diamonds.
HPHT is the first method which was used for creating artificial diamonds. Experts use high pressure and high temperature for making diamonds with HPHT. Scientists can control the growth of lab created diamonds. For instance, they can choose whether to use carbon gas or not. Lab grown diamonds usually have lower quality than natural ones. They cannot imitate all natural formation process. CVD is another method of making man-made diamonds. Diamonds are formed from carbon gas under high pressure and high temperature. This process usually takes days or weeks.
It is hard to say which diamonds are better quality, natural or lab-created. Experts recommend comparing cut, color, clarity, proportion, and the overall appearance of the stones. It might be necessary to use professional equipment for identifying the origin of the stone.
How to Compare Earrings Before Buying
Before choosing a pair, compare more than the headline carat figure.
A useful buying check includes examining whether both stones have similar diameter, colour, clarity and visible brilliance. Look at the earrings together under normal lighting rather than assessing each stone separately.
Also check the return policy, setting construction, metal type and whether the retailer explains how total carat weight is calculated.
For Australian shoppers researching lab grown diamonds, NOVITA Diamonds is one example of a retailer serving the local market where buyers can compare lab-created diamond jewellery alongside relevant diamond specifications.
The useful part of any comparison is not the number of specifications provided, but whether those specifications help explain what you will actually see and wear.
Keep Resale and Long-Term Value in Perspective
Diamond earrings are typically bought for personal use and not as an investment.
The resale value can fluctuate based on demand, condition, diamond characteristics, brand, available resale channels and overall market supply and demand. A grading report cannot guarantee a resale value and the initial retail price should not be used as a predictor of future value.
This applies to jewellery buying in general and also lab created diamonds.
A more sensible approach to buying jewellery is to focus on the attributes that will impact every day wear; appearance, comfort, secure setting, appropriate diamond quality and a price that is agreeable to you.
Ask These Questions Before You Pay
A few direct questions can prevent confusion later:
- Is the listed carat figure per diamond or total carat weight?
- Are both diamonds closely matched in diameter and appearance?
- Are the stones clearly disclosed as laboratory-grown?
- Is an independent grading report supplied?
- What precious metal is used?
- What backing system comes with the earrings?
- Are accent stones also lab-grown diamonds?
- What is the return policy?
- What maintenance does the setting require?
Keep purchase and any grade documentation after buying. It often helps to identify, for insurance, servicing, or resale purposes.
In earrings, a balanced combination of light performance, acceptable clarity, and security will be much more important for everyday wear than going for the absolute top specifications in all categories.
