Lab Grown Diamonds vs Natural Diamonds: Price, Quality & Value Compared

Last month, a customer walked in at our Surat Showroom with a budget of RS.2 lakh and asked us a question "Should I buy a smaller Natural diamond or a bigger lab grown diamond?" Not just her but this is the most common question asked to us. Many people are confused about which diamond is a better choice.

There is no right answer for everyone. This guide won't push you towards one answer. It will explain the difference between lab grown diamond and natural diamond. You'll have the information about quality, price, resale value, grading and which diamond you can choose that best fits for you.

What is a Lab Grown Diamond

A lab grown diamond is a man made diamond formed inside a controlled environment instead of earth mined over billion of years. A lab grown diamond is chemically and structurally the same thing as natural diamond the only difference is how it crystalizes- Carbon is carbon.

Lab Grown Diamonds are made by two methods

How HPHT diamonds are made

High Pressure High Temperature diamonds are tiny carbon seeds compressed under conditions similar to what exists deep in the earth until the seed grows layer by layer into a diamond crystal.

How CVD diamonds are made

Chemical Vapour Deposition works differently. A thin diamond seed is placed in a sealed chamber filled with carbon-rich gas. The gas is heated until carbon atoms separate and settle onto the seed, building the diamond up one atomic layer at a time a bit like snowfall accumulating into a solid sheet of ice, except with carbon atoms.

In 2018, the FTC (U.S. Federal Trade Commission) stated that lab created diamonds are real diamonds. India’s Bureau of Indian Standards (BIS) also recognises lab grown diamonds as real diamonds.

 What Is a Natural Diamond?  

A natural diamond is formed deep inside the Earth over 1 to 3 billion years. It is created when carbon is exposed to very high heat and pressure, causing it to slowly become a diamond.

Because this process takes billions of years, natural diamonds are limited in supply. Once a natural diamond is mined, nature cannot replace it within a human lifetime. This limited availability is one of the main reasons why natural diamonds are usually more expensive than lab grown diamonds.

Lab Grown Diamond VS Natural Diamond

 Price Comparison in India 2026 (INR)  

• 0.5 carat price range (both diamonds, multiple grades)  : At half a carat, a lab grown diamond in G colour, VS1 clarity is nearly  ₹18,000–₹30,000, while a comparable natural diamond is between ₹80,000–₹1,50,000 depending on cut quality and certification.
• 1 carat price range: It is the most-searched size  . A well-cut, IGI-certified 1ct lab grown diamond in G/VS1 typically is between ₹40,000–₹70,000. Whereas the same specification in a natural diamond is between ₹2,00,000–₹4,00,000  which is roughly 4 to 6 times more than Lab Grown Diamond.
• 2 carat price range:  At 2 carats, lab grown pricing typically ranges ₹1,20,000–₹2,00,000, while natural diamonds of the same grade can is between ₹8,00,000–₹15,00,000 or higher. This is the segment where lab grown is opening up statement jewellery - tennis bracelets, large solitaires, cocktail rings to buyers who previously couldn't consider that carat weight at all.

Why Are Lab Grown Diamonds 70–85% More Affordable?  

Lab grown diamonds usually cost 70–85% less than natural diamonds. There are three main reasons for this:

1. No mining is required. Lab grown diamonds are made in a controlled laboratory, so there are no costs for mining, digging, or exploring the earth.
2. Production is more efficient. Many lab grown diamonds are manufactured using advanced technology in places like Surat, which helps reduce production costs.
3. A shorter supply chain. Lab grown diamonds move directly from the manufacturer to the jewellery maker, with fewer middlemen. This helps keep the final price lower.

The lower price does not mean the diamond is of lower quality. Lab grown diamonds have the same physical, chemical, and optical properties as natural diamonds. The difference in price mainly comes from the way they are produced and brought to market.

Understanding the 4Cs: Cut, Colour, Clarity and Carat  

Whether you choose a lab grown diamond or a natural diamond, both are graded using the same 4Cs:

• Cut – How well the diamond is cut, which affects its sparkle.
• Colour – How colourless the diamond is.
• Clarity – The number of natural marks or inclusions inside the diamond.
• Carat – The weight and size of the diamond.

A VS1 clarity or Excellent cut means the same thing for both lab grown and natural diamonds. The grading standards do not change based on how the diamond was made.

Why Do Many Lab Grown Diamonds Have Better Clarity?  

Lab grown diamonds are created in a controlled environment, so they often have fewer inclusions than natural diamonds in the same price range. For the budget of a natural diamond with SI1 or SI2 clarity, you may be able to buy a lab grown diamond with VS or even VVS clarity.

Which Grades Offer the Best Value?  

For most buyers, a diamond with G–H Colour, VS1–VS2 Clarity and Excellent Cut offers the best balance of quality and price. These diamonds look bright, clean, and eye-clean without paying extra for higher grades that are usually visible only under magnification.

Resale Value: What You Should Know  

Many buyers ask, "Will my diamond have resale value?" The answer is yes, but it's important to have realistic expectations.

In general, natural diamonds tend to have a higher resale value than lab grown diamonds. However, both usually sell for less than their original retail price. Unlike gold, diamonds are not usually bought as an investment.

When Resale Matters  

Resale value may be important if:

• You are buying a high-value diamond as a long-term asset.
• Your family prefers natural diamonds because of their traditional value.
• You plan to sell the diamond in the future.

When It Matters Less  

For many people, a diamond is bought to celebrate a special occasion, such as an engagement, wedding, anniversary, or birthday. These pieces are usually kept for years and are rarely sold. In such cases, the difference in resale value may not be a deciding factor.

What Makes Up the Final Price?  

When buying diamond jewellery, you're paying for more than just the diamond. The final price usually includes:

• Diamond Cost – It is based on the diamond's cut, colour, clarity, and carat weight.
• Gold Setting – The price depends on whether you choose 9K, 14K, 18K, or platinum.
• Making Charges – It is the cost of designing and crafting the jewellery and it is typically 8-15% of the gold value.
• GST – A 3% tax on the total jewellery value.
• BIS Hallmarking – A small charge that certifies the purity of the gold.

Understanding these costs helps you compare different jewellery options and know exactly what you're paying for.

• Lab grown diamond jewellery at Maiora Diamonds starts from ₹24,990, depending on the diamond's size, cut, colour, clarity, and overall quality.
• Making charges depend on the gold weight and the design of the jewellery.

Sustainability and Ethics  

Many buyers today also think about how their diamond is made.

Natural diamonds are mined from the earth. Mining can affect land, use large amounts of resources, and in some parts of the world has been linked to conflict. Over the years, systems like the Kimberley Process have helped reduce the trade of conflict diamonds.

Lab grown diamonds do not require mining, so they avoid land excavation. However, making them also uses energy. The overall environmental impact depends on how that energy is produced.

One advantage of lab grown diamonds is that their supply chain is usually shorter and easier to trace. This is one reason why many younger buyers choose them.

Cultural and Astrological Considerations  

Many Indian buyers wonder whether lab grown diamonds are suitable for weddings and traditional occasions.

There is no religious rule that prevents the use of lab grown diamonds in Hindu weddings. For most families, the choice depends more on personal preference and tradition than on religion.

What Does Vedic Astrology Say?  

In Vedic astrology, diamonds are associated with Shukra (Venus). Many astrologers focus on the diamond's quality rather than whether it is natural or lab grown. However, some astrologers recommend natural diamonds for astrological remedies. If you are buying a diamond for this purpose, it is best to consult your family astrologer.

Diamonds for Festivals and Gifting  

Diamonds are often gifted during occasions like Akshaya Tritiya, Dhanteras, Karva Chauth, weddings, and anniversaries.Natural diamonds have traditionally been the preferred choice, but lab grown diamonds are becoming more popular, especially among younger buyers who want a larger or better-quality diamond within their budget.

Talking to Family About Lab Grown Diamonds  

If your family is unfamiliar with lab grown diamonds, explain that they are real diamonds with the same physical, chemical, and optical properties as natural diamonds. Showing the IGI certificate and choosing a traditional jewellery design can also help build confidence.

Which Jewellery Is Best for Lab Grown or Natural Diamonds?  

• Engagement Rings: Lab grown diamonds allow you to choose a larger diamond for the same budget. Natural diamonds may be preferred by families who value tradition.
• Mangalsutras:   Lab grown diamonds are a practical choice for everyday wear because they offer good value and lower replacement cost.
• Solitaire Pendants: Both options work well. Your choice depends on whether you want a larger diamond or prefer the rarity of a natural diamond.
• Tennis Bracelets and Hoop Earrings: Lab grown diamonds are often the better choice because these designs use many diamonds, making natural versions much more expensive.
• Nose Pins and Rings: Lab grown diamonds are a good option for everyday jewellery that is worn frequently.
• Cocktail Rings: Lab grown diamonds make it easier to choose a larger and more eye-catching design without a very high price.

When Should You Choose Lab Grown Diamonds?  

A lab grown diamond may be the right choice if:

• You want a bigger diamond within a practical budget.
• You are buying an engagement ring and want better size or quality for your money.
• You prefer statement jewellery with larger diamonds.
• The jewellery is meant for regular wear and everyday use.

• You want a piece that may become a family heirloom.
• Long-term traditional value is important to you.
• Your family prefers natural diamonds for weddings or important occasions.
• You want the option of higher resale value in the future.

The right choice depends on what matters most to you  size, budget, tradition, or long-term value.

How Different Generations Are Choosing Diamonds in 2026  

Diamond preferences are changing with generations.

Younger buyers, especially Gen Z and millennials, are showing more interest in lab grown diamonds because they offer larger sizes and better value within a budget.

Older generations often continue to prefer natural diamonds because of their traditional connection with weddings, family jewellery, and heirloom value.

Many millennial buyers choose differently based on the occasion  lab grown for everyday jewellery or engagement rings, and natural diamonds for pieces they plan to pass down.

Care and Maintenance: Will It Last for 50 Years?  

Both natural and lab grown diamonds are made of the same material and have the same hardness level (10 on the Mohs scale).With proper care, both can stay bright and beautiful for generations. Diamonds do not fade, lose colour, or become dull with time.

Simple Care Tips:  

• Clean your jewellery with warm water, mild soap, and a soft brush.
• Avoid contact with harsh chemicals like chlorine.
• Get the jewellery setting checked once a year to make sure the prongs are secure.

The diamond itself is extremely durable. Usually, the jewellery setting needs more attention than the stone.

How to Identify Lab Grown vs Natural Diamonds  

Lab grown and natural diamonds look the same to the naked eye. Even a regular jeweller's may not be enough to tell them apart.

Special equipment is needed to identify the difference by checking features such as:

• Growth patterns
• Fluorescence
• Internal characteristics

Most certified lab grown diamonds have a laser inscription on the edge of the diamond, along with a certificate number. Always check that the inscription matches the certificate details before buying.

IGI vs GIA Certification: Which One Should You Choose?  

Certification helps buyers understand the quality and authenticity of their diamond.

IGI (International Gemological Institute) is widely recognised for lab grown diamond certification and is commonly used in India.

GIA (Gemological Institute of America) is one of the most recognised grading institutes for natural diamonds.

Both provide detailed reports about a diamond's quality, including its cut, colour, clarity, and carat weight.

Always verify the certificate number with the issuing organisation before making a purchase.

At Maiora Diamonds, every lab grown diamond comes with an IGI certificate, so customers can check and understand the quality of their diamond before buying.
