So, what shape diamond is the most expensive? Is it round cut diamond, pear shape diamond, oval cut diamond, or something more unique, like heart shaped diamonds? In this guide, we will explore the most expensive diamond cut and other less expensive options that you can find in diamond stores Vancouver.

What Affects the Price of a Diamond?
Every diamond is priced based on the 4Cs of diamond—cut, color, clarity, and carat. These factors determine the overall value of the diamond.
Diamond Cut
This refers to how well the diamond's facets can reflect light. The traditional shape, like the brilliant cut diamond is known to reflect the most light. Fancy shapes like oval shape, radiant cut, and princess cut diamonds also reflect more light than other shapes. Step cut diamonds, like emerald and asscher cut diamonds, have fewer facets and give less sparkle in comparison.
Diamond Color
Less color = more value. Diamonds are graded from D (colorless) to Z (light yellow). The more colorless a diamond is, the more value it has.
Diamond Clarity
Diamond clarity refers to the internal and external flaws of the diamond. These also play an important role in determining the price of a diamond, whether it's a popular diamond shape like a round brilliant diamond or a fancy shape like an emerald cut diamond.
Diamond Carat
Larger diamonds with more diamond carat weight are rarer and more expensive. But some elongated shapes, like oval or marquise cut diamonds, look bigger than other shapes despite having the same carat weight.
Along with the 4Cs, shape itself plays a big role in pricing. Why? Because different shapes use different amounts of the original rough diamond. To learn about what is most expensive diamond shape, read the next section.

How and Why Does Diamond Shape Affect Price?
