Only a few years ago, lab-grown diamonds were a curiosity; today, they are genuinely taking over the jewelry market and changing the perception of diamonds as gemstones. In my experience, customers want to know what diamonds are, how they are made, how lab-grown diamonds differ from natural ones, and why prices can vary so much. In this guide, I illustrate this with specific examples, without marketing simplifications.
- Lab-grown diamonds and prices – specific ranges and real valuations
- Lab-grown diamonds versus natural diamonds – where there is sense, and where there is myth
- Lab-grown diamonds in future jewelry – what has truly changed
- Synthetic diamonds in customer practice – stories from valuations
- Lab-grown diamonds – when I recommend and when I advise against

Lab-grown diamonds – what are they and why do customers ask about them?
Lab-grown diamonds are one of the most frequently discussed categories in the jewelry industry today because they combine the appearance of a real diamond with affordability. A lab-grown diamond is a real diamond – it has an identical crystalline structure, the same chemical properties, and identical physical properties as a natural diamond. If you want to understand how lab-grown diamonds are made and why they are gaining popularity, read on.
From my experience, customers most often ask if it's "just a lab." In practice, it looks like this: lab-grown diamonds are produced under controlled conditions, in a controlled laboratory environment, where scientists mimic the natural process of diamond formation. In nature, natural diamonds form deep beneath the Earth's surface under immense pressure and temperature. In the laboratory, this process is controlled and shortened in time.
Lab-grown diamonds are primarily created using two technologies. The first is the HPHT method, which recreates the pressure and temperature conditions found beneath the Earth's surface. The second is the CVD method, or chemical vapor deposition. In this method, carbon atoms from carbon-rich gases are placed in a sealed chamber, where carbon atoms deposit layer by layer, forming a lab-grown diamond.
An example of a specific stone from my valuation: a lab-grown diamond, 1.00 ct, color E, clarity VS1, cut Excellent. Natural diamonds with such parameters cost approximately 28,000–32,000 PLN in Poland. The same lab-grown diamond costs 6,000–8,000 PLN. For many customers, this is the moment they begin to consciously choose diamonds.
The biggest mistake investors make is thinking that synthetic diamonds will always increase in value. From my experience: it's an excellent alternative to traditional diamonds in jewelry, but not a strictly investment product. If you want to delve into the topic of quality, check out our guide on diamond quality assessment according to the Gemological Institute of America.
Lab-grown diamonds vs. natural diamonds – real differences in price and value
A lab-grown diamond and a natural diamond have the same optical properties, the same hardness, and crystalline structure, but their history is completely different. A natural diamond is formed through a natural process, deep beneath the Earth's surface, and then extracted from the earth. A lab-grown diamond is human-made using advanced technology.
In practice, it looks like this: a customer with a budget of 10,000–15,000 PLN. A natural diamond? A maximum of 0.30–0.40 ct, often with a compromise in color or clarity. A lab-grown diamond? Easily 0.80–1.00 ct with excellent parameters. For many people, this is an obvious alternative.
An example situation of a customer from Katowice: a classic engagement, a jewelry ring, time pressure. We chose a lab-grown diamond, 1.10 ct, F/VS2, which was set by a local jeweler. The result? A visually identical gem to a natural diamond, without aesthetic compromises.
However, I must be clear: natural diamonds win in the context of rarity and long-term value. The natural process of diamond formation takes millions of years, and this cannot be fully replicated. If you have a budget above 50,000–70,000 PLN, I recommend considering natural diamonds or fancy-colored diamonds.
At Diament Expert, we always show both variants and allow customers to choose diamonds independently, without sales pressure. Only with us do you have a guarantee of the lowest price and the possibility of return.
Lab-grown diamonds – example valuations and customer situations
Lab-grown diamonds are currently the most common choice for people who want quality diamonds at a reasonable price. From my experience, customers prefer a larger gemstone with an excellent cut over a small natural diamond with compromises.
Example parameters I most often recommend: weight 0.90–1.20 ct, color E–G, clarity VS1–VS2, cut Excellent. Example valuation from December 2025: lab-grown diamonds 1.05 ct, G/VS1 – price 7,400 PLN gross. The natural equivalent is approximately 29,000 PLN.
Customers ask if lab-grown diamonds can be distinguished with the naked eye. The answer is no. Real diamonds, both natural and lab-grown, have identical optical properties. Differences are visible only with specialized equipment.
The biggest mistake investors make is treating lab-grown diamonds as an investment. However, if the goal is jewelry, lab-grown diamond earrings, or an engagement ring, it is a very rational and balanced choice.
Lab-grown diamonds in the future of jewelry – what I see from the market
Lab-grown diamonds represent a lasting change in jewelry. From my experience, more and more jewelry workshops do not keep natural diamonds in stock. Lab-grown diamonds are available faster, in a controlled environment, and without the risks associated with mining.
Natural diamonds are formed under natural conditions, deep beneath the Earth's surface, and their extraction involves environmental impact. Lab-grown diamonds are created in a more sustainable and ethical way, which is of great importance to many customers today.
Will natural diamonds disappear? No. They will remain as collectible and investment products. For most customers, the future of jewelry is lab-grown diamonds as a conscious alternative.
