If you have ever shopped for a diamond, you know how overwhelming it can feel. There is colour, clarity, carat weight and cut to weigh, and now another C in the picture: Creation.
Lab-grown diamonds are increasingly what people choose, and yet a good deal goes unsaid at the counter. Here is what is worth knowing before you are shown anything.
They are real diamonds, and the counter should say so
The most common thing left unsaid is the simplest. A lab-grown diamond is a real diamond. It has the same carbon crystal structure, the same 10 on the Mohs scale of hardness, and the same brightness and fire as one formed in the earth. It is grown from a diamond seed rather than dug, and IGI grades it on exactly the same 4Cs. The only difference is origin, and origin is a fact that belongs to you, stated plainly and without being asked. Read the full science in our guide to lab-grown vs natural diamonds.
The land a diamond costs
Mining carries a real footprint. One carat of mined diamond disturbs close to 100 square feet of land. One carat grown in a controlled setting disturbs about 0.07 square feet, with far less energy and no landscape left behind. This rarely comes up in a showroom, and it is worth asking about.
What actually separates two diamonds
Here is the part most worth knowing, and the part least often explained. Two diamonds can read identically on paper and look nothing alike on a hand. What separates them is cut, and how the stone handles light.
The 4Cs tell you what a diamond is. They do not tell you how it behaves. A diamond's real beauty is its brightness, its fire (the flashes of colour), and its contrast (the crisp balance of light and dark that makes it look alive). A light performance report measures exactly this, beyond the 4Cs, and most counters will not offer you one.
Ask about the small stones, not only the centre
In a halo, a band or a set, the centre stone is graded and named while the surrounding stones often are not. That is where quality quietly disappears. Ask what colour and clarity the small diamonds are, and ask to see the certificate for the stone you are actually buying.
What to look for in any diamond you are shown
A diamond is easy to grade on paper and harder to judge in the light. Before you choose one, these are the things worth looking for.
- How it handles light. Ask for a light performance report, which grades brightness, fire and contrast beyond the 4Cs.
- Cut, and the precision of it. Cut is where a diamond earns its light. Look for an ideal cut, and for hearts and arrows, a pattern that appears only when a diamond is cut with near perfect symmetry.
- Colour and clarity you can actually name. Ask precisely what you are getting, not only the carat, and for every stone in the piece.
- A certificate that matches the stone. Look for an IGI report whose number is laser inscribed on the diamond itself, so the paper and the stone are one and the same.
Know these, and you can judge any diamond you are shown, in any store, ours included.
The Nivara standard
At Nivara there is one standard, and every diamond meets it.
Every Nivara diamond is VVS in clarity and E in colour. Every one is an ideal cut, hearts and arrows precise. Every one is chosen by our gemologists and passes 27 quality checks before it is ever set. And every one arrives with its own light performance report, so its brightness, fire, and contrast are not described to you. They are measured for you.
We wear diamonds to feel good, and to stand out. That should never come with a compromise. So we do not make one.
The price is stated as plainly as the standard. A Nivara VVS E diamond is ₹50,000 per carat, the same for everyone, with the setting and metal additional. See the working in our guide to lab-grown diamond prices in India. If you want every consideration in one place, here are the disadvantages of lab-grown diamonds, stated plainly.
In short
- Lab-grown diamonds are real diamonds, with the same chemical and physical properties as mined ones, grown rather than dug.
- Mining disturbs close to 100 square feet of land per carat. A grown carat disturbs about 0.07 square feet.
- Cut and light performance separate two diamonds far more than origin ever does.
- The small stones in a piece are where quality quietly disappears. Ask for their grades too.
- A certificate is only proof when its number is laser inscribed on the stone in front of you.
- Every Nivara diamond is VVS E, ideal cut, hearts and arrows precise, IGI-certified, and ships with a light performance report.
Frequently asked questions
Why are some jewellers against lab-grown diamonds?
Usually because their business was built on mined stones. A lab-grown diamond is a real diamond with the same hardness, brightness and fire, graded by IGI on the same 4Cs. A seller who will not state a diamond's origin plainly has told you something useful about the seller.
Are lab-grown diamonds real diamonds?
Yes. A lab-grown diamond has the same carbon crystal structure, the same 10 on the Mohs hardness scale, and the same brilliance as a mined diamond. It is grown from a diamond seed rather than mined. IGI grades it on exactly the same 4Cs and states its origin on the report.
What should I ask a jeweller before buying a diamond?
Ask for the cut grade, the colour and clarity of every stone including the small ones, and an IGI report whose number is laser inscribed on the diamond. Then ask how the stone handles light. A light performance report grades brightness, fire and contrast beyond the 4Cs.
How can I tell if a diamond is good quality?
Judge it in the light, not on paper. Cut decides how much light a diamond returns, so look for an ideal cut and hearts and arrows precision. Then check that the certificate belongs to that exact stone by matching the laser inscribed number on the girdle.
