You are at a jewellery store, and a sparkling engagement ring has won your heart. However, you are unsure about the authenticity of this lab-grown diamond beautifully embedded in the ring.
You know it is shining like a natural diamond, but you don’t know whether it is real or fake.
This blog is written specifically for all those first-time buyers of lab-created diamonds who are a little skeptical about the genuineness of a lab diamond.
Let’s get started!
What Are Lab-Grown Diamonds & How Are They Made?
Lab-grown diamonds are also called synthetic diamonds or man-made diamonds. But it doesn’t mean that they are fake. They are real diamonds, just the process and origin differ.
They do not come from the Earth's mantle. They are created in labs using advanced technology. Scientists replicate the natural diamond formation process using:
HPHT (High Pressure High Temperature): With intense heat and pressure just like it is found under the Earth’s mantle, this technology is used in the labs.
CVD (Chemical Vapour Deposition): It is all about growing diamond crystals layer by layer in a controlled lab environment.
Through these processes, a diamond is created that is physically, chemically, and optically identical to a natural diamond.
But the catch is that this diamond is eco-friendly and often more affordable. As you know, there is no need for mining, land digging, and water usage.
To the naked eye, you cannot tell the difference between natural and lab-grown diamonds.
How to Verify a Lab-Grown Diamond’s Authenticity
Whether you buy a natural diamond or a lab-grown diamond jewellery, you invest your hard-earned money, and thus authenticity matters the most.
Here are some practical steps to verify the originality of your lab-grown diamond:
1. Request Certification
Always ask for a grading report from a reputable gemological lab, such as:
- International Gemological Institute (IGI)
- Gemological Institute of America (GIA)
A lab-grown diamond certification check ensures that your diamond has been independently tested for cut, colour, clarity, and carat weight. The certificate will clearly state that it is a lab-grown diamond.
You can even use the IGI report number search to confirm details before making a purchase.
2.Examine the Stone Under Magnification
A real lab diamond will have natural growth inclusions visible under a jeweller’s loupe (a small magnifying tool). If a diamond looks too flawless, it could be cubic zirconia or another simulant.
Checking inclusions helps ensure you are choosing lab-grown diamond earrings or rings that are genuine and not imitation stones.
3. Use Diamond Scanning Technology
Modern diamond testers and scanning machines can analyse the internal structure of a diamond. Real lab-created diamonds display specific growth patterns that distinguish them from simulants.
If you’re buying from a trusted seller like Svaraa, our team will be happy to show your diamond passing advanced technology tests for peace of mind.
Perform the Fog Test
Breathe lightly on the diamond and observe:
- Real diamonds disperse heat quickly, so the fog disappears almost instantly.
- Fake stones may hold the fog for a few seconds longer.
This is a simple check, but it works as a quick indicator alongside professional verification.
5. Ask for Thermal and Light Tests
Lab-grown diamonds have thermal conductivity and light refraction properties that differ from fake ones. Sellers can demonstrate these tests to confirm authenticity. Cubic zirconia or glass simulants will fail under these checks.
H3 - 6. UV Light Testing
Under UV light, real lab-grown diamonds often exhibit a unique fluorescence pattern depending on their growth process (HPHT or CVD). This is another layer of verification for genuine stones.
Are Lab-Grown Diamonds Worth Buying?
Yes, they are worth investing in because:
- They are real diamonds with the same brilliance and durability as natural stones
- They are ethically sourced and eco-friendly
- They offer better value at the same price point
Whether you are shopping for engagement rings, stud earrings, necklaces, or bracelets, certified lab-grown diamonds give you confidence in your purchase.
A diamond isn’t just a stone; it is something you cherish for generations to come. Thus, it is essential to verify the authenticity of your lab-grown diamond so that it gives you peace of mind for a lifetime.

FAQs
Q1. What is the difference between certified and non-certified lab-grown diamonds?
Certified lab-grown diamonds come with an independent lab report verifying their quality and authenticity, while non-certified ones don’t. Buying certified ensures transparency and protects you from misrepresentation.
Q2. How can I check if a lab-grown diamond is real?
The most reliable way is through certification. Additionally, lab-grown diamonds often have laser inscriptions on the girdle, which can be matched with the certificate number for verification.
Q3. Which labs certify lab-grown diamonds?
Reputable organisations like the International Gemological Institute (IGI), Gemological Institute of America (GIA), and SGL are commonly trusted for lab-grown diamond certification.
