Not all shapes are price the same:
The most expensive shape of a diamond depends on several factors such as the quality of the diamond, its carat weight, and the market demand. However, generally speaking, round brilliant cut diamonds tend to be more expensive compared to other shapes, all else being equal.

This is because round diamonds are the most popular and in-demand shape, and the manufacturing process to create a round diamond involves cutting away more rough diamond material than other shapes, resulting in higher wastage. Additionally, the round brilliant cut is designed to maximize the diamond’s fire and brilliance, making it a very desirable choice for many people.

However, the price of a diamond ultimately depends on its unique characteristics and the market demand at the time of purchase.

Diamond of the same exact weight can look very different depending on the proportions and the shape
Diamond shapes that have larger surface area or table size relative to their weight will generally appear larger for their carat weight.

Therefore, diamond shapes that have a shallow depth or a large table are likely to appear larger than other shapes of the same carat weight. Here are some diamond shapes that are known for appearing larger for their carat weight:
Pear-shaped diamonds: The elongated shape and pointed end of a pear-shaped diamond give the appearance of a larger diamond.
Oval-shaped diamonds: Similar to pear-shaped diamonds, the elongated shape of an oval-shaped diamond can make it appear larger than other shapes of the same carat weight.
Marquise-shaped diamonds: The football-like shape of a marquise diamond can also make it appear larger for its carat weight.
Princess-cut diamonds: The square shape of a princess-cut diamond means that it has corners, which can make it appear larger than a round diamond if not cut with a depth over 70%.
Emerald-cut diamonds: The step-cut faceting of an emerald-cut diamond can make it appear larger, even though it has a smaller surface area than other shapes of the same carat weight.
