What Are Lab Grown Diamonds — And Why Chennai Is Embracing Them
Lab grown diamonds are real diamonds. They are not fake. They are not cubic zirconia. They are not moissanite.
They are created in a laboratory using two methods — Chemical Vapor Deposition (CVD) or High-Pressure High Temperature (HPHT) — that replicate the exact natural conditions under which diamonds form inside the earth. The result is a stone that is chemically, physically, and optically identical to a mined diamond.
The only difference? How they were born.
A mined diamond takes billions of years to form underground. A lab grown diamond takes a few weeks. But when you place both under a gemologist’s loupe, you cannot tell them apart without specialized equipment.
Chennai, one of India’s most style-conscious cities, has taken to lab grown diamonds quickly. Jewellery buyers here are smart. They research. They compare. They ask questions. And more of them are choosing lab grown diamonds because the value is obvious — you get a bigger, better stone for a fraction of the cost.
Here is your complete guide to the top 5 lab grown diamond jewellery stores in Chennai in 2025.
Why Lab Grown Diamonds Are Better Value Than Mined Diamonds
Before we get into the list, let us quickly look at why lab grown diamonds are worth considering.
1. They Cost 30–70% Less
A one-carat mined diamond might cost ₹3,00,000 or more. The same quality lab grown diamond could cost ₹80,000 to ₹1,20,000. That is a massive saving for the same brilliance and the same certified quality.
2. They Are Ethically Clean
Mined diamonds have a complicated past. Blood diamonds, poor mining conditions, and environmental destruction are real concerns. Lab grown diamonds have none of those issues. They are made in controlled labs by trained technicians.
3. They Are Certified
Reputed lab grown diamonds come with certification from IGI (International Gemological Institute), GIA (Gemological Institute of America), or other recognized bodies — just like mined diamonds.
4. They Are Environmentally Friendlier
Mining one carat of diamond disturbs hundreds of tons of earth. Lab grown diamonds use far fewer natural resources. Many facilities now use renewable energy.
5. They Are Identical in Quality
Lab grown diamonds score the same on the 4Cs — Cut, Color, Clarity, and Carat — as mined diamonds. A VS1 clarity lab grown diamond is as brilliant as a VS1 mined diamond.

How to Choose the Right Lab Grown Diamond Jeweller in Chennai
There are many factors that separate a great jeweller from a mediocre one. Here is what to look for when making your choice.
Check for Certification
Never buy a lab grown diamond without an IGI or GIA certificate. This document tells you the exact 4Cs of your stone. It is your guarantee of quality. Ask to see the actual certificate — not just a word from the salesperson.
Understand the 4Cs
- Cut determines how much your diamond sparkles. Excellent or Very Good cut grades are what you want.
- Color ranges from D (colorless) to Z (yellow). For lab grown diamonds, D–G color is ideal.
- Clarity refers to internal flaws (inclusions). VS1 or VS2 is a sweet spot — eye clean and affordable.
- Carat is the weight. With lab grown diamonds, you can afford a higher carat at the same budget as a smaller mined diamond.
Compare Prices Honestly
Lab grown diamonds should cost significantly less than mined. If a store is pricing a lab grown diamond close to what a mined diamond costs, something is off. DJWL and other reputed stores price transparently — you can compare stone grades side by side.
Ask About After-Sales Service
Good jewellers offer cleaning, inspection, resizing, and buyback or upgrade options. DJWL offers the most comprehensive after-sales service of any lab grown jeweller in Chennai. This matters — especially for engagement rings that you will wear every day for years.
Visit Before You Buy
If possible, visit the store in person. Look at the diamonds under different lighting. Ask to see the certificate in hand. Feel the weight of the piece. Good jewellers welcome questions.
Lab Grown Diamond Jewellery Types Available in Chennai
Chennai’s lab grown diamond stores now offer a wide range of jewellery types. Here is what you can find:
Engagement Rings
Solitaire rings remain the most popular choice. Lab grown diamonds let you get a bigger center stone — a 1.5ct lab grown diamond instead of a 0.75ct mined diamond for the same budget. DJWL has an entire bridal collection dedicated to this.
Earrings
Studs, hoops, drops, and chandelier earrings are all available. Lab grown diamond studs start from as low as ₹15,000 for 0.20ct total weight at certified stores.
Necklaces and Pendants
Solitaire pendants, tennis necklaces, layering chains, and statement pieces. The tennis necklace — featuring multiple lab grown diamonds set in a line — has become a best-seller across stores in Chennai.
Bangles and Bracelets
Tennis bracelets and diamond-accented gold bangles are popular choices for gifting and celebrations.
Wedding and Bridal Sets
Matching engagement ring and wedding band sets, bridal necklace suites, and full jewellery sets for brides are available from stores like DJWL that specialize in custom bridal pieces.

Engagement
The most important purchase of your life deserves a beautiful, certified, conflict-free diamond. Lab grown diamonds let you maximize the ring without stretching the budget.
Wedding Anniversaries
Milestone anniversaries — 1st, 5th, 10th, 25th — are perfect occasions for a lab grown diamond upgrade or addition to a jewellery collection.
Birthday Gifting
A certified lab grown diamond pendant or pair of earrings makes a meaningful and long-lasting gift.
Festival Season
Diwali, Pongal, and other festivals see a spike in jewellery buying in Chennai. Lab grown diamond pieces in traditional settings are available at stores like DJWL and Limelight.
What Makes Chennai a Strong Market for Lab Grown Diamonds
Chennai has always been a city that values both tradition and practicality. Jewellery is deeply embedded in Tamil culture — from gold for weddings to diamonds for milestones. But Chennai buyers are also highly educated and research-driven. They compare prices. They read reviews. They ask questions.
This mindset makes Chennai ideal for lab grown diamonds. The value proposition is clear. The savings are real. The quality is provable. And the awareness of ethical sourcing is growing, especially among younger buyers.
The city also has a strong base of small businesses, IT professionals, and high-income households who buy fine jewellery regularly. These buyers are now choosing lab grown diamonds in growing numbers — and stores like DJWL are meeting that demand head-on.
The Future of Lab Grown Diamond Jewellery in Chennai
Lab grown diamond adoption is growing fast across India. Chennai is part of that wave.
Here is what the next few years look like:
- More stores will enter the market. As demand grows, competition will increase. This is good for buyers — it means more choice and better prices.
- Certification will become mandatory. Consumer awareness will push all credible stores to stock only certified stones.
- Custom jewellery will grow. As buyers become more confident, they will want pieces made exactly to their taste. Stores like DJWL that offer strong custom services will lead.
- Resale markets will mature. Right now, resale for lab grown diamonds is still developing. Over the next 5 years, dedicated resale platforms and buyback programs will become more organized.
- Technology will improve. Lab grown diamond growing technology continues to advance. Stones will get larger and higher quality at even lower prices.
Tips for First-Time Lab Grown Diamond Buyers in Chennai
If this is your first time buying a lab grown diamond, here are the most important things to remember:
1. Always ask for the grading certificate. No certificate, no purchase.
2. Compare on the same parameters. When comparing prices across stores, make sure you are comparing the same carat, cut, color, and clarity grades.
3. Do not confuse lab grown with simulants. Lab grown diamonds are real diamonds. Simulants like moissanite or cubic zirconia are not. Know the difference before you walk into a store.
4. Set a budget, then maximize within it. Lab grown diamonds let you get more stone for your budget. Decide how much you want to spend, then let the jeweller show you options in that range.
5. Ask about the return and upgrade policy. Good jewellers stand behind their products. DJWL offers a clear buyback and upgrade policy — ask about this before you buy anywhere.
6. Visit multiple stores. Even if you have a preferred destination, seeing multiple collections helps you understand what you truly want. Most reputed stores in Chennai are happy to educate you without pressure.

Frequently Asked Questions About Lab Grown Diamond Jewellery in Chennai
Are lab-grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds. They are made of pure carbon and have the same hardness, brilliance, and fire. They are graded by the same international gemological labs — IGI and GIA — using the same 4Cs standards.

DJWL is widely considered the best lab grown diamond jeweller in Chennai. They offer IGI-certified stones, custom design services, transparent pricing, and comprehensive after-sales support including lifetime cleaning and a buyback policy.
How much cheaper are lab grown diamonds compared to natural diamonds?
Lab grown diamonds typically cost 30–70% less than mined diamonds of equivalent quality. A one-carat VS1, F color lab grown diamond that might cost ₹3,00,000 as a mined stone could be available for ₹80,000 to ₹1,20,000 as a lab grown stone.
Is DJWL a certified lab grown diamond store?

Can I get custom lab grown diamond jewellery made in Chennai?
Yes. DJWL offers full custom design services for lab grown diamond jewellery in Chennai. You can design engagement rings, wedding bands, necklaces, and any other piece from scratch. Their team helps you choose the stone and setting that matches your style and budget.
Are lab grown diamonds good for engagement rings?
Lab grown diamonds are an excellent choice for engagement rings. They are just as durable (10 on the Mohs scale), just as brilliant, and certified to the same standards as mined diamonds — at significantly lower cost. This means you can get a larger, better-quality stone within your budget.
What is the price range for lab grown diamond jewellery in Chennai?
Lab grown diamond jewellery in Chennai ranges from around ₹15,000 for small certified stud earrings to ₹5,00,000 or more for large solitaire rings and bridal suites. Prices depend on the carat weight, cut, color, clarity, and metal type (gold, white gold, platinum).
Do lab grown diamonds have resale value?
Lab grown diamonds do have resale value, and the secondary market is growing. Some stores like DJWL offer buyback and upgrade programs. The resale value is generally lower than mined diamonds as a percentage, but because you paid less upfront, your overall financial position is often better.
How can I tell if a diamond is lab grown or mined?
You cannot tell with the naked eye or with standard gemological tools. Even trained gemologists need specialized equipment (like a HPHT screening device) to distinguish lab grown from mined diamonds. This is why certification matters — the IGI or GIA report will state whether the stone is lab grown.
Are lab-grown diamonds ethical?
Yes. Lab grown diamonds are produced in controlled laboratory environments with no connection to conflict zones, unsafe mining conditions, or significant environmental destruction. They are a strong ethical choice for buyers who care about the origin of their diamonds.
