There are many factors to consider when you buy diamonds. Small details play a big role in determining the value of the stone. Diamonds are tricky with their pricing. A small diamond may be more expensive than a bigger one sometimes. It may be because of its superior cut, colour or clarity.

While picking up a ring, there is a lot of pressure involved. You have to select the best of the best that will not break your budget but will look like a splurge.

The 4Cs of the diamond

The 4Cs of the diamond is the carat, colour, cut and clarity. These are the primary factors that determine the diamond quality and the price of the stone. Gemologists grade diamonds according to them to different cut grades, clarity grades and colour grades. Even the diamond shape and rarity too play a big role in determining its worth.

When it comes to buying diamonds as jewellery, the question is, what type of diamond you would buy? The shape of a diamond very much influences the price of the stone and also its visual appeal.

For example, a round-shaped diamond displays the full brilliance of the stone. It is sparkly and radiant. An emerald cut diamond, on the other hand, gives the effect of a half mirror and is more demure.

What are the most expensive diamond cuts in order?

Let’s get straight to the point. Let’s now look at the diamond cuts from the priciest to the cheapest.

  • Round Brilliant Cut: This one is the most expensive cuts. This is due to its high demand and the large loss of material during cutting.
  • Oval, marquise, and pear shape: These are pricey because they are elongated stones and take skill to be cut.
  • Asscher cut: The next pricier one. This one too loses a lot of material when working it.
  • Princess cut and Radiant Cut: Not as much of a budget breaker as they are square or rectangular shaped. The wastage is very less; thus they are cheaper.
  • Cushion and Heart shape: The perfect cuts, packing both great brilliant and fits the budget.
  • Emerald shape: These are the least expensive shape, but they are such a classic too!

The round cut is of a different game. It costs about 20%-40% more than other fancy-shaped diamonds of the same carat weight. Talk about vanity!

How to buy a diamond?

Time needed: 5 minutes

Wondering what are the steps you need to keep in mind before buying a diamond? Don’t worry! We have a step by step guide for you.

  1. Fix a budget

    Start by fixing your budget. Since there are too many choices, the budget can really narrow down your playground.

  2. Finalise the piece of jewellery you wish to buy

    Decide on what piece of jewellery you wish to buy. If they are necklaces, you can go for more number of diamonds than bigger diamonds itself if it’s a ring, its best to go the other way round.

  3. Get into the details

    Know your cut, colour and clarity. Talk to the jeweller about the latest cuts and why they are trending. Don’t hesitate to ask for your favourite cut. The right diamond may be hiding in plain sight.

  4. Try it on for fit

    Try. And try again. I can’t stress enough how important this is. Diamonds are all about beauty and grace. Try it on for fit and make sure that you love it before you swipe the card.

  5. Check well before buying

    Watch out for poorly cut and defected diamonds. Check well before you buy one.

  6. Be careful of the metal used

    Also, be careful of what metal the diamond is encrusted on. White diamonds in round cut look stunning on a white gold setting, whereas emerald cut diamonds are more becoming alongside yellow gold!


Choosing the right diamond shape can be really tricky. You need to find the balance between what you like, the cut and the price. Along with cut, colour and clarity are also key. If you want something truly unique, a yellow or pink diamond can be a good choice. They are extremely rare and can be a great eye-catcher.

Of course, try it on repeatedly before making this huge investment. After all the look matters for jewellery. As different diamond shapes offer unique fire and brilliance, it’s imperative to take your partner along when choosing for her.
