What are lab grown diamonds?

Lab grown diamonds are diamonds created in a controlled laboratory environment rather than formed by geological processes in the Earth. The Gemological Institute of America explains that laboratory-grown diamonds possess essentially the same chemical, physical, and optical properties as their natural counterparts, while their origin and growth history differ. GIA also identifies high-pressure, high-temperature (HPHT) and chemical vapour deposition (CVD) as two laboratory growth methods.

That distinction matters because a diamond’s origin should be disclosed clearly. A laboratory-grown diamond is not the same thing as a diamond simulant such as cubic zirconia or moissanite. When comparing a lab-grown diamond with other stones, ask for the exact stone description, any available grading report, and the seller’s terms in writing.

What to compare before you buy

The familiar 4Cs—cut, colour, clarity, and carat—are a useful starting point. They are not a complete buying decision, but they help you compare like with like when two stones look similar in a product photograph.

Cut and sparkle

Cut describes how a diamond’s proportions, facets, symmetry, and finish return light. Shape is the outline you see—round, oval, emerald, pear, marquise, or another silhouette—while cut quality affects the way that shape performs in light. If sparkle matters most to you, compare videos or viewing appointments rather than relying on a single still image.

Colour and clarity

Colour and clarity are graded characteristics, not simple measures of whether a stone is “good” or “bad.” A slightly warmer colour may be difficult to notice once a stone is set in yellow gold, while a clarity grade that looks impressive on paper may not be visible to the naked eye. Compare the stone, the metal, and the setting together.

Carat and proportion

Carat measures weight, not the face-up size that your eye sees. Two stones with the same carat weight can look different because of shape, depth, table proportion, and setting. A well-proportioned smaller stone may be a more satisfying choice than a heavier stone with weaker light performance.

Documentation and disclosure

Ask whether the stone comes with a grading or identification report, who issued it, and whether the report identifies the stone as laboratory-grown. Ask what happens if the ring needs resizing, repair, or an exchange. These practical details are part of value, especially for an engagement ring that may be worn every day.

Where to browse lab grown diamonds in Australia

For a first look at styles, you can browse LAVANA’s lab-grown diamond collection, which presents diamond earrings, pendants, necklaces, bracelets, bangles, and ear cuffs in one category. Treat a collection page as a discovery tool, then open the individual product page for the precise metal, stone, dimensions, price, availability, and care information.

If you are comparing more than one jeweller, make a short table of the details that matter to you. The Tikli material index can help you translate metal and stone terminology, while the journal archive keeps related buying notes in one place.

Care, setting, and the life of the piece

Before buying, decide how the piece will be worn. A pendant or earring may have different practical needs from a ring exposed to impact, handwashing, and daily friction. Follow the maker’s specific care guidance for water, chemicals, storage, and cleaning. Also check whether the warranty covers manufacturing issues, stone security, plating, resizing, or accidental damage.

Good buying decisions are rarely about finding a single “best” stone. They are about matching origin, proportion, setting, service, and budget to the person who will wear the piece. For a broader view of what makes jewellery worth keeping, read the Tikli Jewelry about page.

Frequently asked questions

Are lab grown diamonds real diamonds?

Yes. Lab grown diamonds are diamonds created in a laboratory, with essentially the same chemical, physical, and optical properties as natural diamonds. Their origin is different and should be disclosed clearly.

What are the main lab grown diamond growth methods?

The two commonly discussed methods are HPHT, which uses high pressure and high temperature, and CVD, which deposits carbon from a carbon-rich gas onto diamond seeds.

Should I ask for a grading report?

Ask what identification or grading documentation is provided, who issued it, and whether it identifies the stone as laboratory-grown. Keep the report with your purchase records.
