If you have been searching for "lab created", "lab grown diamonds", or the popular spelling "labgrown diamond" online, you have probably noticed something the terminology is confusing, the marketing is loud, and every brand suddenly claims to be an expert. This guide cuts through all of that.
We are the team at Goenka Jewellers, one of eastern India's first dedicated lab grown diamond destinations, with showrooms in Kolkata and Delhi. We sell these stones and the jewellery built around them every single day. The same questions come up repeatedly: Are they real? Why are they cheaper? Will they last? Where do I start? This guide answers all of them, in the order Indian buyers actually ask.
Lab Created or Lab Grown Diamonds , Are They the Same Thing?
Yes. Completely.
"Lab created", "lab grown", "lab made", "cultured", "engineered", and the no space variant "labgrown diamond" all describe the exact same real diamonds grown in a laboratory using one of two scientific methods. There is no difference in quality, structure, or value. The terms are fully interchangeable.
The reason multiple names exist is partly marketing, partly translation across global markets. In India, "lab grown diamonds" has emerged as the dominant term. In the United States, "lab created" is more common. They mean the same stone.
What Exactly Is a Lab Grown Diamond?
A lab grown diamond is pure crystallised carbon, the exact same atomic structure as a mined diamond. The only difference is origin.
Mined diamonds form deep inside the earth under extreme heat and pressure over a billion or more years. Lab grown diamonds form the same way through heat, pressure, and carbon except scientists recreate those conditions inside a controlled lab over four to eight weeks. The result is, by every measurable property, a diamond.
This is why the United States Federal Trade Commission officially removed the word "natural" from the diamond definition in 2018, and why every major gemological institute including GIA and IGI - now certifies lab grown diamonds using the same 4Cs grading system as mined ones.
How Are Lab Grown Diamonds Made?
There are two scientific methods used to grow these stones:
CVD (Chemical Vapour Deposition). The dominant method for jewellery grade lab grown diamonds in 2026. A tiny diamond seed is placed inside a chamber filled with carbon rich gas. Heat breaks the gas down, and carbon atoms settle layer by layer onto the seed, growing it into a full diamond crystal. CVD produces high clarity stones with consistent quality and is the preferred method at Goenka Jewellers.
HPHT (High Pressure High Temperature). The older method, which mimics the earth's natural diamond forming conditions directly. Carbon is subjected to roughly 1.5 million PSI of pressure and temperatures above 1,400°C. HPHT is also used to enhance the colour of some natural and labgrown stones.
The vast majority of stones sold in India in 2026 including our Goenka lab grown diamonds collection are CVD grown because of their superior clarity and consistency.
Are Lab Grown Diamonds Real Diamonds?
Yes. Without qualification, lab grown diamonds are real diamonds.
They are not cubic zirconia. They are not moissanite. They are not "diamond simulants" of any kind. A certified labgrown diamond will:
- Pass every standard diamond tester. (thermal and electrical conductivity)
- Show identical refractive index and dispersion as a mined diamond.
- Score 10 on the Mohs hardness scale, the highest possible.
- Sparkle and behave under light exactly like a mined diamond.
The only way to distinguish a lab grown diamond from a mined one is through specialized, gemological equipment that detects trace nitrogen patterns and growth structures. To the human eye, even under a jeweller's loupe, they are indistinguishable.
Lab Grown Diamond Jewellery - What You Can Actually Buy
These stones work in every category of fine jewellery. At Goenka Jewellers, the most popular pieces are:
- Engagement Rings - solitaires, halos, hidden halos, three stone designs, and oval centre stones. (the biggest engagement trend of 2026).
- Bridal Sets - necklaces, chokers, mangtikas, and jhumkas built with lab grown diamonds let brides assemble elaborate sets at a fraction of mined diamond costs.
- DailyWear Studs and Pendants - these stones make it realistic to wear larger diamonds every day, not save them for occasions.
- Tennis Bracelets and Diamond Lines - pieces with many stones become dramatically more affordable when grown in a lab.
- Men's Rings and Studs - a fast growing 2026 category for confident, daily wear pieces.
- Mangalsutras and Anniversary Bands - traditional designs at honest, modern pricing.
This is the practical advantage, lab grown diamonds let Indian families buy more, bigger, and better jewellery within the same budget.
Quality and Certification - What to Demand
Every lab grown diamond you buy should come with an independent certificate. The Indian standard in 2026 is IGI (International Gemological Institute). Some premium stones may also carry GIA grading.
At Goenka Jewellers, every stone is sold with its IGI report, every band carries a BIS hallmark, and every invoice itemises stone grade, metal weight, and making charges separately. No mystery, no markedup bundles.
Do Lab Grown Diamonds Last Forever?
Yes. They have identical hardness, durability, and longevity to mined diamonds. They do not cloud, fade, dull, or lose sparkle over time. A lab grown diamond will look exactly the same in fifty years as it does on the day you buy it.
Resale Value - The Honest Answer
This deserves real honesty.
The resale market for any diamond in India is historically weak. Most diamond jewellery is bought for personal use, gifting, or generational holding, not for resale. The honest framing is this: buy a labgrown diamond because it lets you afford the piece you actually want, not as a financial investment.
Goenka Jewellers offers a certified buyback and lifetime exchange policy on all our pieces, giving you a clear value pathway if your needs ever change.
