What Exactly Is a Lab-Grown Diamond?

Laboratory-grown diamonds are neither cubic zirconia (CZ) nor moissanite. According to GIA, laboratory-grown diamonds share many of the same physical, chemical, and optical characteristics as natural diamonds. The primary distinction between the two types of diamonds is their source of creation; natural diamonds are formed in the earth while laboratory-grown diamonds are created through controlled manufacturing processes like HPHT (high pressure high temperature) and/or CVD (chemical vapor deposition).

The difference in their growth structure may be determined through the use of specialized laboratory equipment; therefore, an independent evaluation and accurate reporting are important.

Buyers Can Do More With the Same Ring Budget

The strongest reason to purchase is price. Lab-grown buyers can either get a larger center stone, better specifications, a more elaborate band, or just a lower total cost.

In addition to allowing for greater flexibility when designing, this freedom allows couples to consider the design as a whole; rather than having to make many compromises in terms of selecting a center stone and its accompanying setting, they can think about the complete piece of jewelry and how their engagement ring and wedding band will ultimately fit together.

Australian consumers are demonstrating that they are also shifting their purchasing habits. For example, over 12 months (July 2025 – June 2026), Diamondport, a jewelry store located in Brisbane, sold 173 engagement rings. Of those 173 rings, 58.4 percent contained lab-grown center stones. Although the data was collected from just one retailer's customer base, it provides a good indication of how the local market is evolving.

They Offer the Same Fundamental Diamond Appeal

The rise of lab cultured diamonds is reflective of a more knowledgeable buyer base. Buyers have become more aware of the fact that lab-grown diamonds are actual diamonds as opposed to mere representations.

Therefore, consumers can continue to assess key aspects of a diamond’s appearance (including shape, proportions, clarity, color, and general light performance) when shopping for one. After that, they can create a design based around the center stone that is consistent with the way a ring is constructed, whether it be a solitaire, halo, trilogy, etc.

More Design Freedom Encourages Personalisation

Large oval, radiant, and emerald cut center stones can open up a world of possibilities for customers who would have had to make significant reductions in the size of their center stone. Additionally, any money saved from purchasing the center stone can be used towards other features such as platinum, custom designs, or additional diamonds.

The center stone of an engagement ring is just one aspect of the choice; however, the ring setting will affect the security, height, comfort, and ability to pair your engagement ring with a wedding band in the future.

Couples who are looking at other items than just their engagement rings can find coordination in the metals and diamond detailing of these additional pieces of jewelry.

Are Lab-Grown Diamonds Automatically the More Sustainable Choice?

Lab-grown diamonds do not involve the use of diamond mining. However, there are many factors that contribute to the overall environmental footprint of lab-grown diamonds. These include how they were manufactured, the source of energy used during manufacture, the efficiency of the manufacturing process, etc. Therefore, it is important to take broad statements about being "eco-friendly" with caution until a seller can provide data to support these claims. The FTC (Federal Trade Commission) has issued similar guidelines regarding false or misleading environmental benefit claims by businesses.

When looking for a diamond, those who are particularly concerned with the environment can find out if the diamond was mined, how much energy was required to mine it, and if there is any evidence that can prove this.

The Bottom Line

Understanding Why Lab Diamond Engagement Rings Are Growing in Popularity is related to the change in how buyers purchase. Buyers are able to obtain a real diamond, have greater design options, and can potentially get a larger size of diamond for their budget.

For some people, lab-grown is not always the most appropriate choice. People who consider geological rarity to be an important factor in their decision-making process or those who have strong preferences about secondary market potential may continue to purchase natural diamonds. A better strategy would be to compare origin, diamond quality, certification, budget, and the completed ring setting prior to making a final decision regarding what type of diamond is best suited for the individual wearing it.
