Diamonds are broadly classified into natural, lab grown, treated, and fancy coloured types. Each has its own characteristics, price point, and ideal use case. This guide breaks it all down simply so you can buy with confidence.
Buying a diamond is one of the most meaningful purchases you will ever make. But with so many options available, it is easy to feel overwhelmed before you even begin. Walk into any jewellery store or browse online and you will come across terms like natural diamonds, lab grown diamonds, treated diamonds, and fancy coloured diamonds. What does each one mean? How are they different? Which one is actually worth your money? And which type works best for an engagement ring versus everyday jewellery?
This guide answers all of it, clearly and without jargon, so you can walk into your next jewellery purchase feeling informed and confident.
What Are Diamond Types ?
When people talk about types of diamonds, they usually mean one of two things: how the diamond was formed and sourced, or what it looks like in terms of colour, clarity, and treatment. Both matter more than most buyers realise. Two stones of the same carat weight can look completely different, carry very different price tags, and suit entirely different occasions depending on their type.
Understanding diamond types helps you ask the right questions before you buy. It helps you compare options fairly, avoid being misled, and choose a stone that gives you the best value for your money. A diamond's origin, structure, and appearance all affect its value, durability, and how it looks set in jewellery. Getting familiar with these basics is the first step toward making a purchase you will never regret.
Natural Diamonds
Natural diamonds are formed deep within the Earth over billions of years under extreme heat and pressure. They are mined, cut, polished, and set into jewellery.
They are graded on four parameters: cut, colour, clarity, and carat weight, known as the 4Cs. These factors determine the quality and price of every natural diamond.
For many buyers in India, natural diamonds carry traditional and emotional significance, especially for engagement rings and generational gifting. The blog on what are VVS diamonds is a helpful read if you want to understand diamond clarity better.
Lab Grown Diamonds
Lab grown diamonds are created in a laboratory using processes that replicate the exact conditions under which natural diamonds form.
The result is a diamond that is chemically, physically, and optically identical to a mined diamond. Same hardness. Same brilliance. Same fire. The only difference is origin.
Lab grown diamonds are priced significantly lower than mined diamonds of the same quality. Buyers get more carat, more clarity, and more sparkle for their budget. For pricing details specific to India, the lab grown diamond price guide is worth reading before you buy.
Natural vs Lab Grown: Which Is Better?
The answer depends entirely on what matters to you.
If heritage, geological rarity, and long-term resale value are your priorities, a natural diamond makes sense. If you want outstanding quality at a smarter price with full certification and ethical sourcing, a lab grown diamond is the better choice.
For everyday jewellery, engagement rings, and gifting, lab grown diamonds offer exceptional value without compromising on beauty. The lab grown diamond jewellery collection at Ivana Jewels is entirely lab grown, IGI certified, and handcrafted in-house.
Treated and Enhanced Diamonds
Treated diamonds are natural diamonds that have undergone processes to improve their appearance. Common treatments include laser drilling, fracture filling, and high-pressure high-temperature colour enhancement.
Treated diamonds are generally less expensive than untreated natural diamonds. However, their enhancements can affect long-term durability and resale value.
Always ask for full disclosure and certification that clearly states the type of treatment applied. Transparency from your jeweller is non-negotiable.
Fancy Coloured Diamonds
Most diamonds fall somewhere between colourless and slightly yellow on a standard grading scale. Fancy coloured diamonds are different. They display vivid, saturated hues including yellow, pink, blue, green, and red.
Natural fancy coloured diamonds are extremely rare and among the most expensive gemstones in the world. Lab grown fancy coloured diamonds offer the same visual impact at a far more accessible price point.
For buyers who want something truly distinctive, a fancy coloured diamond ring or pendant makes a memorable and unique choice.
Diamond Types Based on Shape
Diamond type is also sometimes used to refer to shape, which confuses many buyers.
The round brilliant is the most popular shape in India and globally. Beyond that, fancy shapes include oval, pear, princess, cushion, emerald, marquise, and radiant cuts. Each shape has a distinct personality and suits different jewellery styles.
The complete guide to fancy shape diamonds at Ivana Jewels covers every non-round shape in detail and helps you decide what works best for your hand and style.
Which Type of Diamond Is Best for Your Jewellery?
The best diamond type depends on how and where the piece will be worn.
For engagement rings, a natural or lab grown diamond in a solitaire or multi-stone setting is the most popular choice. Browse the diamond rings collection at Ivana Jewels for engagement-ready designs.
For everyday jewellery, lab grown diamonds are ideal. Durable, certified, and cost-effective enough to wear daily without worry.
For necklaces and pendants, a well-cut solitaire in a simple setting is a timeless choice. The diamond necklaces collection at Ivana Jewels has designs that work from daywear to occasions.
For gifting, the diamond jewellery gifts for her collection has beautifully curated options across every budget.
How to Choose the Right Diamond Type
Keep these four things in mind before buying.
Set a clear budget. Lab grown diamonds give you more quality for the same spend. Natural diamonds carry rarity value. Treated diamonds are most affordable but come with compromises.
Prioritise the cut. Across all diamond types, cut has the greatest impact on how a diamond looks. A well-cut diamond will always outshine a poorly cut one of higher carat or clarity.
Always ask for certification. Your diamond should come with a grading certificate from IGI or GIA. This tells you exactly what you are buying. The blog on how to choose the right lab grown diamond jewellery is a great pre-purchase read.
Consider the cultural context. Diamond jewellery holds deep significance in Indian culture and tradition. The blog on the significance of diamond jewellery in Indian culture offers meaningful perspective before you make a purchase.
Conclusion
There is no single best type of diamond. There is only the right diamond for your needs, your budget, and the meaning you want it to carry.
Natural diamonds bring rarity and heritage. Lab grown diamonds bring quality, ethics, and value. Fancy coloured diamonds bring personality and distinction.

FAQs
What are the main types of diamonds?
The main types are natural diamonds, lab grown diamonds, treated or enhanced diamonds, and fancy coloured diamonds. Natural diamonds are mined from the Earth. Lab grown diamonds are created in a laboratory with identical properties. Treated diamonds are natural stones enhanced to improve appearance. Fancy coloured diamonds display vivid hues beyond the standard white to yellow range.
Are lab created diamonds real diamonds?
Yes, completely. Lab created diamonds are real diamonds in every meaningful sense. They are chemically, physically, and optically identical to mined diamonds. Same hardness, same brilliance, same fire. They are graded using the same 4Cs and come with IGI or GIA certification. The only difference is they are grown in a laboratory rather than mined from the Earth.
Which type of diamond is best for everyday jewellery?
Lab grown diamonds are the best choice for everyday wear. They are just as durable as natural diamonds and come fully certified. Their lower price point means you can invest in higher clarity or a larger carat stone without stretching your budget. They are also ethically sourced, which matters to many modern buyers in India.
Are coloured diamonds more expensive than white diamonds?
Natural fancy coloured diamonds are typically far more expensive due to their rarity. A natural pink or blue diamond can cost significantly more than a colourless stone of the same carat. Lab grown fancy coloured diamonds offer the same visual impact at much more accessible prices, making them an excellent choice for buyers who want something distinctive without the premium.
How can I tell what type of diamond I am buying?
Always ask for a grading certificate from IGI or GIA. The certificate clearly states whether the diamond is natural, lab grown, or treated, along with its cut, colour, clarity, and carat weight. Buy only from jewellers who provide full certification and transparent sourcing. If no certificate is offered, that is a red flag.
