Types of diamond stones

Types of diamond stones

1. Natural Diamonds

natural diamond

These are simply uncut, unpolished diamonds that occur in nature. Forming under extreme pressure, natural diamonds are the hardest material found on earth. They are white or colourless.

2. Treated Or Enhanced Diamonds

Treated Or Enhanced Diamonds

These are enhanced or artificially improved versions of natural diamonds. The enhancement is made to improve the appearance of the diamonds. Laser drillings, fillings, colour enhancement, and other techniques are used to improve the inclusions (natural flaws) in the diamonds. Such diamonds are cheaper than natural diamonds.

3. Coloured Diamonds

Coloured Diamonds

Natural coloured diamonds are one of the rarest and the most beautiful creations of nature. During the crystallization under the earth, certain particulates are caught inside giving them the red, pink, brown, blue, green, yellow, violet and other hues that are a spectacular feast for the eye. Treated coloured diamonds are enhancements made on natural coloured diamonds.

4. Artificial Diamonds

Man-made or lab-grown diamonds are created with technology. Such diamonds are cheaper and can be mass-produced at low costs.

The 4 Cs

Cut and polished diamond

Diamonds are judged on the criteria of 4 Cs. Read our depth article on how to buy diamonds here.

1. Carat weight

It’s measured in points. 100 points equal to 1 carat. 50 points equal to 0.50 carats. The bigger the better is true in this sense, but not always. A diamond with low carat weight can be more precious than a bigger diamond,  as the other Cs also make an impact.

2. Colour

The scale here goes from D to Z. D stands for absolute colourlessness, Z stands for a light yellowish hue. The more colourless it is, the more expensive it is.

3. Clarity

The scale used here is F to 13. F stands for flawless and allows light to flawlessly, The scale gradually moves up based on the inclusions or flaws in the diamond.

4. Cut

Cuts are a personal choice and do have an effect on the value. They are made to make the best use of light, so the diamond sparkles. More on that later.


The diamond certificate is meant to ensure the guarantee of quality, as authenticated by a non-partial professional lab. Look for GIA, AGS, EGL or IGI certifications.

Diamond Jewellery: The Price Factor

To quote an example, let’s assume you’re buying a diamond solitaire ring. The price will be determined by the 4 Cs.

  • Cut: This depends on your preference. But don’t choose a diamond that is too deep or too shallow.  
  • Colour: Ideally, choose grade H or above representing near colourlessness (grades G to J) and complete colourlessness (grades D-F).
  • Carat weight: To maximise the budget, select a carat slightly shy of the full mark, e.g. 0.9 rather than 1 carat.
  • Clarity: choose eye-clean diamond over VS1 scale with no visible flaws.

Just because the caratage is high, doesn’t mean the diamond becomes automatically more expensive or perfect, because if the clarity, cut, and colour are not up to the mark, the diamond may not be as valuable as you think. The design and craftsmanship play an important role too, as symmetrical facets, proper finishing and intricate cutting are required manually.

The 4 Cs mentioned above will determine the price of the diamond jewellery. As a rule, always check the diamond pricing guidelines online before buying diamonds.

The surest way to buy the best diamond jewellery that fits your budget is by considering which factors are the most important to you. Each scale of the 4 Cs is available online for your perusal.

If you don’t care about what people will say about the size of the rock, settle for a lower carat weight and give equal weight to the cut and the colour.

Or if you just want to possess a fancy riviera necklace or a tennis bracelet for occasional party wear without a major financial setback, go for Cubic Zirconia.

The rarest coloured diamonds, also the most expensive are pink, purple, blue, violet and orange diamonds, however when the scales of 4Cs tip in the favour of clear diamonds, they become more expensive. When it comes to diamond jewellery and the price determination, it’s all relative! The design, base metal, craftsmanship, every single component matters. So do your research thoroughly before investing in diamond jewellery. It helps to buy online from a renowned brand or to visit a retailer which has outstanding brand recognition and loyalty.

Currently, the diamond that is high on all 4 C scales (including the most expensive round or princess cut on 1-carat diamond) can cost over $5000 to $6000 (Rs. 3,00,00 lakh onwards).

In the mid-range, the piece of jewellery that is less in carats, but made by reputed jewellery houses can cost anywhere between Rs. 20,000 to Rs. 1,00,000 lakh. (excluding small studs and nose pins). Jewellery made with American diamonds is way more affordable starting at Rs. 2000 to Rs. 10,000 for earrings, necklaces, etc.
