Simple Hacks To Find Lab-Grown Diamonds

How To Find Lab-Grown Diamonds  

Diamonds are being produced in contemporary times, both in high-end laboratories and far below the Earth's crust.  Many people are now inquiring, now that diamonds produced through advanced technology are no longer deemed unusual: how would you know if the diamonds that you possess were produced in a lab? Regardless of your reasons to know how to identify a lab-grown diamond, it is necessary to be informed in making a purchase, personal or for moral or resale purposes.  Let's explore the methods for identifying lab-grown diamonds, if your diamonds are lab-grown, and distinguishing between lab-grown and natural diamonds. 

1. Knowing from the Beginning: What Are Lab-Grown Diamonds?

It is important to know if your diamonds are lab-grown diamonds before being able to identify them. This is quite literally as simple as it sounds. The diamonds were produced under controlled conditions utilizing either Chemical Vapour Deposition (CVD) or High Pressure High Temperature (HPHT) methods. Therefore, the stone produced is structurally, chemically, and visually the same crystal structure as naturally mined diamonds.  They are man-made stones, not from the Earth.

Lab-grown diamonds have been available in the jewelry market since they were first brought into the market. They are accepted and popular because of the value for money, sustainability, and traceability.  In addition, their brilliance and similarity to naturally mined diamonds is a win-win gemstone. But with such close resemblance, recognizing them requires deeper investigation, often beyond the naked eye.

2. Test for Certification

Certification can be one of the most reliable ways of knowing whether your diamonds are lab-grown or not. It's the identification of your diamonds. Reputable gemological laboratories issue grading reports stating whether the diamond is lab-grown or natural. Reputable laboratories include the Gemological Institute of America (GIA), International Gemological Institute (IGI), and GCAL.

Most lab-grown diamonds will also have laser inscriptions on the girdle. These inscriptions can be seen with a jeweler's loupe or 10x magnification.  It may say something along the lines of “Lab Grown IGI LG12345678,” for example. Make sure you always ask for the certification that corresponds with the inscription. If you are purchasing from a jeweler, making sure you obtain a certified certificate is the easiest and most reliable solution for identifying lab-grown diamonds.


3. Look for Telltale Inclusions and Growth Patterns

The growing environment does leave specific internal characteristics, but lab-grown diamonds are structurally the same as natural diamonds. Which means a gemologist with a jeweler's loupe can easily note the patterns, such as:

  • Metallic inclusions a more prevalent in an HPHT (high-pressure, high-temperature) diamond.

  • Grain lines, or striations, are seen in CVD (chemical vapor deposition) diamonds.

  • Clouds or pinpoint inclusions from both types.

These small inclusions can act like fingerprints that can help in identifying lab-grown diamonds, but it does not take away from the diamond's sparkle. If you are unsure, then it would be good to talk to a gemologist who has studied diamonds.

4. Investigation with Professional Equipment

There are equipment and tools specifically designed to tell the difference between lab-grown and natural diamonds. Jewelers and gem labs use advanced equipment like 

  • DiamondView (by De Beers):  A machine that utilizes ultraviolet light to outline growth features indicative of natural vs synthetic diamonds.

  • FTIR Spectroscopy:  Useful for detecting absorption signatures

  • UV Fluorescence Tests: Some natural diamonds fluoresce under UV light, while CVD diamonds tend not to.

If you want to find out the origin of the diamond, you can ask a gemological lab to perform these tests, even though most of these tools won't be available for your use. These advanced testing methods offer one of the best testing modalities to identify lab-grown diamonds that cannot be identified with the naked eye.

5. Know the Price and Source

You can request these tests from a gemological laboratory if you are hell-bent on knowing where the diamond came from, but these methods typically aren't for personal use.  These tests, sometimes referred to as "advanced" tests, provide some of the best methods of tracing lab-grown diamonds that can't be seen from sight. 

In addition to this process, it is important to buy from reputable jewelers who disclose the origin.  Transparency is the main aspect of building trust, and ultimately the deciding factor for any brand.  In this case, transparent dealers will mostly say whether the diamond is natural or synthetic, which is basically for the identification of diamonds. But other dealers could keep it close to the vest. It is best practice to ask for proof of origin and not buy from a seller who has a problem sending you evidence of a certification.


Although lab-grown diamond jewellery is available in a variety of styles, each item is genuinely unique due to its clarity, cut, and specifications. These diamonds are rated similarly to real ones; brilliance is affected by intrinsic imperfections, which are measured by clarity and range from perfect to included. Whether the cut is cushion, emerald, or round, it determines how well the diamond interacts with light to dazzle. To assist you in selecting a piece that suits your taste and price range, the profile is completed with details like carat weight, colour grade, and polish. Whether you're choosing bracelets, rings, or earrings, knowing these elements guarantees that every lab-grown gem will be beautiful, valuable, and ethically brilliant.

Transparency is part of today's expectation when it comes to responsible retailing.  If you are questioning the origin, do your due diligence to seek other affirmation or have your diamond tested.

6. Conclusion

Lab-created diamonds are gaining traction as the demand for ethical and sustainable jewelry increases. This shift presents new possibilities for buyers, but it also renders the skill to identify lab-grown diamonds crucial. The ideology of this approach consists of knowledge, official

What are the signs that the diamonds you hold were created in a lab?   Let us begin with the document. Check out laser engravings.   With a jeweler's loupe, check for inclusions. Identification of diamonds is necessary. Take into consideration hiring an expert to evaluate your equipment.   Buy from reputable companies that value transparency as well. In the end, both lab-grown and natural diamonds hold beauty and brilliance. But knowing exactly what you're buying empowers you to make informed choices, whether it’s for customization, investment, sentiment, or simply personal style.

 

5 Faq’s For Determining Lab-Grown Diamonds

1. How do I know if a diamond is lab-grown?

You cannot tell by simply looking at the diamond with the naked eye. You need a professional test or certificate as proof of origin. Qualified laboratories such as IGI and GIA have proven certifications.

2. Do lab-grown diamonds have inclusions like natural diamonds?

Yes, lab-grown diamonds can possess inclusions, and they may have fewer, or they can be otherwise structurally different from natural diamonds. Inclusions can also likely depend on the growth type -- HPHT or CVD.

3. Are lab-grown diamonds marked or inscribed?

Most lab-grown diamonds are engraved or laser inscribed on the girdle of the diamond. The engraving is usually just the report number and/or the words “LAB-GROWN” because they are sufficiently colored or different physically to be easy to identify or verify the origin.

4. Can a jeweler tell the difference simply by sight?

No, lab-grown diamonds look and appear identical to their natural counterpart. A jeweler may use some advanced tools, but the naked eye does not. Wholesale dealers typically use tools like spectrometers with visible light and may even check with a 15x magnifier.

5. Does a lab-grown diamond need a certificate?

Yes, certificates are important because they provide proof of authenticity and quality. IGI and GIA are trusted laboratories and provide detailed grading reports of lab-grown and natural diamonds. Before you purchase a diamond, please remember to always ask for a certificate.
