Lab Diamonds vs Real Diamonds: A Simple 2026 Guide for Everyday Buyers
If you have been searching for diamonds online in 2026, you have definitely seen two terms everywhere: lab diamonds and real diamonds. And honestly, it can get confusing very fast. Are they the same? Are lab diamonds fake? Why are they more affordable?
Let’s break it down in the simplest and most honest way, so you can choose confidently.
What Exactly Are Lab Diamonds?
Lab diamonds, also called Lab Created Diamonds known as LGD, are real diamonds grown inside controlled laboratories instead of being mined from deep below the earth.
They are made using advanced technology that recreates the natural process of diamond formation. In short, they are manufactured diamonds, but with the same sparkle, hardness, and chemical structure as mined diamonds.
Think of it like growing a plant in a greenhouse versus growing it in open soil. Both are real plants. Only the environment is different.
Are Lab Diamonds Real Diamonds? Yes, 100 Percent
A lot of buyers still ask:
“Are lab diamonds real?”
The answer is simple: YES.
Whether created in a lab or mined from the earth, a diamond is made of pure carbon crystal.
Both have:
• Same hardness
• Same brilliance
• Same chemical structure
• Same grading reports
• Same look and feel
This is why jewellers across India now openly promote LGD, and many younger buyers even prefer them.
How Are Real Diamonds Different?
Real diamonds, or natural diamonds, are formed over billions of years under intense heat and pressure deep within the earth. They are rare and therefore more expensive.
So when comparing lab diamonds vs real diamonds, the biggest difference is not the quality. It is the origin. Some buyers love the idea of owning something naturally formed over millions of years. Others prefer modern, ethical, and pocket friendly LGD options. Both are valid choices.
The Core Differences Between Lab Grown and Natural Diamonds (2026 Update)
Here is a simple comparison to help you understand the differences between lab grown and natural diamonds clearly:
1. Origin
• Lab Diamonds (LGD): Made in laboratories using CVD or HPHT technology.
• Real Diamonds: Formed naturally beneath the earth’s surface.
2. Price
• Manufactured diamonds cost 40 to 70 percent less than natural diamonds, depending on size and quality.
• This is the reason many couples and buyers in India now choose LGD for engagement rings.
3. Environmental Impact
• LGD has a lower environmental footprint because there is no mining involved.
• This makes lab diamonds a popular choice among eco conscious shoppers.
4. Value
• Natural diamonds retain value because they are rare.
• Lab diamonds focus more on affordability and accessibility.
5. Availability
• Lab diamonds are easier to find in exact shapes, sizes, and clarity because they are grown in controlled conditions.
Why Lab Created Diamonds Known as LGD Are Popular in India in 2026
In the last two years, the Indian market has seen a huge shift.
People now want:
• Higher carat sizes without overspending
• Ethical and eco friendly options
• Modern designs
• Transparent pricing
This is exactly why Lab Created Diamonds known as LGD have become one of the fastest growing jewellery choices. From engagement rings to everyday wear, you see them everywhere — malls, jewellery stores, online shops, and influencer recommendations. Even major Indian jewellers now offer full LGD collections.
Are They Safe to Buy? What About Certifications?
Absolutely. Just like natural diamonds, lab diamonds also come with certification from international labs such as:
• IGI
• GIA
• SGL
Your LGD will have details about cut, clarity, colour, carat weight, and laser inscription. This makes them trustworthy and investment confident for everyday buyers.
Are lab diamonds better than real diamonds?
They are not “better”; they are simply different. Natural diamonds are rare and traditional. Lab diamonds are ethical, affordable, and modern. Choose based on your preference.
Do lab diamonds sparkle the same?
Yes. They sparkle exactly like natural diamonds because they have the same chemical structure and light behaviour.
Are manufactured diamonds fake?
No. Manufactured diamonds are real diamonds. They are not cubic zirconia or moissanite.
Which lasts longer: lab or natural?
Both last forever. Both score 10 on the Mohs hardness scale.
Should I buy lab diamonds in 2026?
If you want a bigger, budget friendly, ethical diamond, then yes — LGD is perfect for you.
Final Thoughts: Which One Should You Choose in 2026?
If you love the idea of owning a natural gem formed over billions of years, then real diamonds are the right choice for you. They hold emotional and traditional values.
But if you want modern luxury without overspending, lab grown diamonds known as LGD give you the same brilliance, same beauty, and same durability at a much easier price.
The best part? No one can tell the difference — except your wallet.
