You’ve been going along, living your life, blissfully unaware of terms like “Asscher cut,” “inclusions,” and “carat.” Then you fall in love and decide to get married, and suddenly you’re researching diamond certification and learning about the differences between cushion cuts and emerald cuts.

It can be a bit overwhelming if you let it. Or it can be an opportunity to expand your horizons and become a connoisseur of sorts. If you’ve already started looking for a diamond ring, you’re well aware that diamonds come in a variety of shapes.

As you weigh the many factors leading up to your final decision, you’ll probably consider cost as a primary determinant. Be aware that some diamond shapes are more expensive than others. In this post, we’ll look at how diamond ring shapes compare in cost.


Supply and Demand

One of the most significant factors in diamond shape cost is supply and demand. The shapes that are most in demand tend to be the most expensive. If you want to buy well, you might want to consider buying a diamond that is a less common shape, especially if your loved one prefers unique jewellery.

Round diamonds are the most popular shape, so they’re generally more expensive than other stones. Classic and traditional in appearance, round diamonds are a perennial favourite, but you’ll pay a premium for their popularity.

The least popular diamond shapes are usually heart-shaped, marquise, and Asscher cuts, although trends change often and can increase or decrease demand considerably.


Rankings by Price

As you search for the perfect diamond ring, it can be helpful to know where the best values are and how much you can expect to spend for different diamond shapes. For this reason, we’ve put together price rankings of the most common diamond shapes. The most expensive cut is first, and the least is last. Let’s take a look.



Always popular, round diamonds are sparklers, and that’s one of the reasons they’re so well loved. Because of their round shape, their brilliance and dispersion add a stunning focal point to any engagement ring. Unfortunately, these diamonds are the most expensive at the popular 1.0 carat mark.


With nearly the same brilliance as round diamonds, ovals are another extremely popular shape, and that’s why they command high prices. Especially attractive in East-West settings, oval diamonds are elegant, and they hide their inclusions well. They are very popular today.


If you’re looking for something unique, consider choosing a pear-shaped diamond. Pear shapes generally have a larger face for their weight than round stones, and they have been gaining in popularity lately.


In the middle price range, cushion cut diamonds are fiery with flashes of coloured light. The cushion cut is common in antique diamond rings, but recently we’ve seen a resurgence in their popularity. A downside is that their faces are about 8% smaller than the faces of rounds for the same carat weight.


Truncated corners and tons of sparkle are the signatures of radiant-cut diamonds. They cost significantly less than rounds, but their face sizes are about the same. This shape is exceptionally durable, so it’s an excellent choice for an active person.


With their sharp edges and dramatic cuts, princess diamonds are one of the most brilliant cuts, perfect for someone who loves sparkle. Their long diagonal edges make them appear larger than they are, which is an added bonus.


Instead of intense sparkle, emerald cut diamonds have a classic shape and are considered to be timeless. They’re not too “blingy,” if that’s what you’re looking for. A lovely, understated emerald cut diamond makes a sophisticated statement.


Reminiscent of the roaring ’20s, Asscher cut diamonds have a mesmerising windmill pattern, which perfectly suits vintage settings. Again, because demand for this shape is low, you can often find them for less than you’d spend on a similarly sized round or oval.


An eye-catching stone that offers impressive value for its carat size, the marquise a stone shape worth investigating. Think of an oval with sharp points on both ends. It’s great for showing off long fingers and makes an elegant solitaire or centre stone.


With a face size slightly smaller than rounds, heart-shaped diamonds are usually the least expensive cuts available on the market. These romantic symbols make memorable engagement rings.
