A Guide to Lab-Grown Diamond Jewelry
The GoldHaus guide · Updated 8 October 2026
A beautiful piece starts with a few clear decisions: the diamond's origin, the way it sits on you, and the gold and setting that bring it together. This guide explains what to look for when choosing lab-grown diamond jewelry in Dubai, whether you are considering a ring, a necklace or earrings.

What is a lab-grown diamond?
Lab-grown diamonds are created in a controlled environment. As GIA explains, they have essentially the same chemical composition, crystal structure and optical and physical properties as natural diamonds. Their origin is different: one grows in a laboratory, the other forms in the earth.
Two principal growth methods are high-pressure, high-temperature (HPHT) and chemical vapor deposition (CVD). A lab-grown diamond is also different from a diamond simulant: moissanite and cubic zirconia are different materials, even when they resemble diamond.
Lab-grown or natural: what should you compare?
Start with the origin you want, then compare the individual stones and the finished jewelry. The label alone does not tell you how a stone will look or how well a ring will fit your hand. Ask for the dimensions, relevant quality information and details of the setting. Gemological testing can identify origin; appearance alone is not a reliable test.
For a GoldHaus purchase, use the lab-grown diamond jewelry collection to browse finished pieces. This guide is about choosing jewelry; the collection is not a loose-stone inventory.
Look beyond a single carat number
Diamond quality is commonly discussed through the 4Cs: cut, color, clarity and carat weight. Use them as a starting point, then consider the complete design.
- Cut and shape: shape describes the outline, such as round or pear. Faceting and proportions affect how a diamond interacts with light. Ask for clear images or a video of the actual piece or proposed stone.
- Color and clarity: compare the specifications supplied for the design. A listed range is not an individual grading report for every stone.
- Carat weight: this measures weight. It does not by itself describe the visible dimensions or the footprint of a finished piece.
Pay particular attention to ctw, or total carat weight. A ring described as 3ctw may spread that weight across several diamonds; it does not necessarily contain a single 3ct center stone. Ask how the weight is divided if that distinction matters to your choice.
Two GoldHaus examples
Etta is listed with round diamonds and 3ctw. Noma Band is listed with round diamonds and 3.5ctw. Both product descriptions list D/E/F color and VVS/VS clarity ranges. These details help you compare the designs, but neither total weight alone tells you how the ring will sit on your hand.
What to ask about a grading report
Where an individual diamond has a grading report, ask which laboratory issued it and which stone it covers. Use the issuing laboratory's own verification service to check the report number and compare the documented details with the proposed stone.
For a design with multiple small diamonds, ask what quality information is supplied for those stones and whether any report covers an individual center stone or the jewelry as a whole. Do not assume every small diamond has its own report. Confirm the documentation for your chosen piece before ordering.
Choose the jewelry around how you will wear it
Rings: think about the whole silhouette
Consider the band width, the height of the setting and whether you want the ring to sit beside another band. Look at photographs on a hand as well as product close-ups. Confirm your ring size and ask about the dimensions of the selected design.

Necklaces: pendant and chain work together
A pendant's dimensions and the chain length both influence where the jewelry sits. Consider your usual neckline, whether you will layer it, and the chain-length options on the product. A close-up communicates detail; a worn photograph helps communicate scale.
Earrings: check what the listing includes
Confirm whether the piece is sold as a pair or a single earring, the dimensions and the fastening. If a pair is described by total carat weight, ask how that total is shared between the two earrings.
Gold, color and the selected variant
The GoldHaus catalog includes designs with 14k and 18k choices. The selected gold option matters: 18k gold contains 75% gold by weight, while 14k contains about 58.3%. Check the specific product and variant rather than assuming every option has the same fineness or price.
Compare yellow, white and rose gold against pieces you already wear. For example, Etta offers all three colors and separate 14k and 18k variants. Confirm the exact combination you want before checking its price.
Before you place your order
- Choose the design and confirm its size, dimensions and selected gold variant.
- Clarify individual versus total diamond weight and the quality information supplied.
- Confirm any grading documentation that applies to the chosen piece.
- Check the current price in your selected currency and the order total.
- Review the shipping and returns policy; ask about timing and any customization before ordering.
