The Velur Diamond Studio
Find your diamond.
Over 90,000 certified stones—we'll show you the ones that are worth taking a closer look at.
Carat 1 carat = 0.2 g and determines the size of the stone. You can choose freely from our entire inventory.
Colour Colour scale D (pure white) through Z. D–F are considered “colourless,” G–J “nearly colourless”; below that, a yellow tint becomes more noticeable.
Fancy Colours Coloured diamonds (e.g., pink, blue). "None" shows only white stones.
Purity How free the stone is of tiny inclusions. FL/IF = flawless, VVS/VS = eye-clean (invisible to the naked eye).
Cut The quality of a diamond's cut determines its sparkle. EX = Excellent, VG = Very Good.
Aspect ratio (L/W) Length divided by width—the most important shape characteristic for oval, marquise, and pear shapes.
Proportions Table % and depth % describe the cut proportions. For round cuts, the classic proportions are: table 54–60%, depth 60–63%.
Rondiste The narrow edge between the upper and lower sections. Medium-sized steps (THN–STK) are considered ideal.
Growth Methods CVD and HPHT are the two manufacturing processes—they are of equal quality.

Buying lab-grown diamonds: real diamonds, grown in a lab
Every stone in this search is a genuine, certified diamond—whether lab-grown or mined. We curate our selection in real time from the inventory of international cutting workshops, rather than presenting you with an anonymous catalog of 400,000 items. We would use what you see here in our own jewellery.
At Velur, you can purchase IGI- or GIA-certified lab-grown diamonds and natural diamonds—either loose or as a finished ring from our studio. Lab-grown diamonds cost up to 80% less than comparable natural diamonds, while offering identical physical properties. We offer personalised consultations via WhatsApp, with no obligation and no pressure to buy.
A lab-grown diamond is not an imitation. Chemically, physically, and optically, it is the same material as a natural diamond—pure carbon in a diamond crystal lattice, with a hardness of 10 on the Mohs scale. The only difference lies in how it is formed: instead of forming over billions of years in the Earth’s mantle, it is grown in a reactor in just a few weeks using the CVD (chemical vapor deposition) or HPHT (high-pressure, high-temperature) process.
Even a gemologist can't tell the two apart with the naked eye. That requires laboratory equipment—and that's exactly why every stone from our collection comes with an independent certificate that states its origin in black and white.
Want to dig a little deeper? We've put together a guide explaining exactly what a lab-grown diamond is and why lab-grown diamonds are real diamonds.
How much does a lab-grown diamond cost?
The honest answer: significantly less than most people think. Following the price decline of recent years, you can now get gemstone sizes that would have cost five figures ten years ago for a fraction of that price. As a guide—market ranges for very high quality (colour G–H, clarity VS1–VS2, cut Excellent), as of 2026:
| Carat | Laboratory-grown diamond | Natural diamond (comparable) |
|---|---|---|
| 0.50 ct | approx. 300–500 € | approx. 1,500–2,500 € |
| 1.00 ct | approx. 800–1,200 € | approx. 4,500–7,000 € |
| 1.50 ct | approx. 1,200–1,800 € | approx. 8,000–13,000 € |
| 2.00 ct | approx. 1,800–2,500 € | approx. 15,000–25,000 € |
Market ranges for loose stones, unmounted. You can see the current daily prices for our natural diamonds right at the top of the search bar.
For lab-grown diamonds, we’ll give you the price during your personal consultation—including the setting—so you end up with one total price instead of three. You can read about how prices have changed and where they’re headed in our 2026 Lab-Grown Diamond Price Analysis.
Lab-grown diamond or natural diamond—which one is right for you?
Both are genuine diamonds. The decision isn't a matter of quality, but rather a matter of budget and significance.
| Laboratory-grown diamond | Natural Diamond | |
|---|---|---|
| Origins | Weeks in the lab (CVD/HPHT) | Billions of years in the Earth's mantle |
| Chemical Properties & Hardness | identical (carbon, Mohs 10) | identical |
| Price per 1 ct | approx. 800–1,200 € | approx. 4,500–7,000 € |
| Certificate | IGI/GIA, origin verified | IGI/GIA |
| Distinguishable? | only in the lab | only in the lab |
| Rarity | reproducible | Finally—every mine runs out |
Based on our experience in consulting, we’ve observed that those who want maximum size and brilliance within their budget choose lab-grown diamonds—usually 1 to 2 carats. Those who love the idea that the stone is older than life on Earth choose natural diamonds and opt for a slightly smaller size. Neither choice is wrong.
Are you still torn between three options? Here's a direct comparison: moissanite vs. lab-grown diamond vs. natural diamond.
The 4Cs — How to Identify Diamond Quality
Four criteria determine the price and quality of each diamond. You can filter by all four in the search bar above.
Karat (weight)
1 carat = 0.2 grams. More important than the number is how the diamond looks on your finger: A well-cut 1.5-carat diamond appears larger than a poorly cut 2-carat diamond. With oval and marquise cuts, you get more visible surface area per carat than with a round brilliant cut.
Colour
The scale ranges from D (colourless) to Z (yellowish). Our recommendation: G to H. Without a direct comparison, no one can tell the difference between D and F—but they can certainly see the price difference. Learn more: Diamond Colours D–F Explained.
Clarity
What matters isn't the lab grade, but whether inclusions are visible to the naked eye. Starting at VS2, they're practically never visible—use the "Eye-Clean" filter in your search. Why VVS stones are often not worth the money when it comes to lab-grown diamonds: VVS1, VVS2, VS1 in lab-grown diamonds.
Cut
The underrated factor—it determines the stone’s brilliance. Don’t skimp here: Excellent or Ideal—nothing less. A poor cut turns a D-Flawless stone into a dull one.
IGI or GIA Certificate: Why It Matters
Don't buy a diamond without an independent certificate. Period. The certificate documents the 4Cs, the origin (lab-grown or natural), and includes a report number that you can verify yourself online with the institute—it takes less than a minute with IGI and GIA. Many stones also have the number laser-engraved on the girdle.
Every diamond in our search results is IGI- or GIA-certified; you’ll receive the certificate along with the stone. What sets these institutes apart and how to read a report: IGI, GIA, and GRA compared.

Frequently Asked Questions About Lab-Grown Diamonds
Are lab-grown diamonds real diamonds?
Yes. They are composed of the same crystalline carbon as natural diamonds, with identical hardness (Mohs 10), brilliance, and refractive index. The major gemological institutes (IGI, GIA) also classify them as genuine diamonds—with their laboratory origin clearly stated on the certificate.
Is it possible to tell a lab-grown diamond from a natural diamond?
With the naked eye or under a jeweller's loupe: no. Only specialised laboratory equipment can detect the growth structure. Therefore, the origin is always verified by the certificate, not by visual inspection.
How much cheaper are lab-grown diamonds?
Depending on size, 70 to 85% of the price of comparable natural diamonds. A 1-carat lab-grown diamond in G/VS quality costs approximately €800–1,200, while a natural diamond of the same quality costs €4,500–7,000 (as of 2026).
Are lab-grown diamonds a good investment?
No, and we’re not claiming otherwise. Prices have fallen significantly in recent years because production is becoming more efficient. Buy a lab-grown diamond for what it is: maximum brilliance and size for your budget—not as an investment. If you’re looking for value retention, consider large, high-quality natural diamonds.
What do CVD and HPHT stand for?
The two methods used to produce laboratory-grown diamonds. In CVD (Chemical Vapor Deposition), the diamond grows layer by layer from a carbon-containing gas; in HPHT (High Pressure High Temperature), it grows under conditions similar to those in the Earth’s mantle. Both methods produce genuine diamonds; the method used makes no difference to the final result on your finger.
How does the consultation work—and how much does it cost?
Via WhatsApp, with a real person, free of charge and with no obligation. Send us your desired stone or your wish list, and we’ll get back to you with availability, the final price, and an honest assessment. You can then take your time to decide.
