These Diamond Shapes Look the Biggest, Have the Most Sparkle and are the Least Expensive

There are a number of choices when it comes to diamond shape, and while it is a matter of personal style and preference, we help you pick the best ones below.

What are the different diamond shapes?

There are 10 main diamond shapes that we will discuss today.

Which diamond shape looks the biggest?

How large diamonds look is often referred to as their "face up" area. This is what you see when a diamond is mounted in a setting. According to the International Gem Society (IGS), the diamond shapes that look the biggest include: Marquise, Oval, Round and Pear-shaped diamonds. The diamond shapes that look the smallest include: Asscher, Princess, Cushion and Heart-shaped diamonds.

Which diamond shape is the cheapest?

The cheapest diamond shape depends on the size of the diamond. IGS did an analysis based on G Color, VS2 diamonds from Blue Nile. Take a look at the table below, where the bolded values represent the cheapest average prices for each size. For example, for 0.50 carat diamonds, Emerald-shaped offer great value, for 1 carat, Asscher-shaped offer the best value, and for 2 carat, pear-shaped offer the best value. At a high level, round and pear are some of the most expensive, whereas emerald and cushion are often some of the least expensive.

Which diamond shape has the most sparkle?

The sparkle of a diamond generally depends on the number of facets that a diamond has, as the light reflects off the many angles an leads to the most sparkle.

Another factor with the sparkle is the quality of the cut. As we discuss in The Guide, we recommend at least Very Good cut in order to ensure a high level of sparkle for your diamond.

Long's Jewelers has put together a diamond shape power ranking. Towards the top with the most sparkle are Round diamonds, and towards the bottom are Cushion, Emerald, Asscher and Radiant.

Most Brilliant: Round

Extremely Brilliant: Oval, Marquise, Pear

Very Brilliant: Heart and Princess

Brilliant: Cushion, Emerald, Asscher, Radiant

The Verdict

The diamonds that look the biggest and have the most sparkle (e.g. Round, Oval, Pear, Marquise) are also some of the most expensive. However, as you can tell from the table above, the difference in shape results in a couple hundred dollar difference, whereas the carat size of the diamond drives the majority of the price difference. The bottom line is that you should choose the diamond shaped based on the style of your significant other not price or "face up" size.

A great way to figure out what shape your significant other wants is by asking her friends to find out for you--it is something they may have already talked about, but if not, they can find a subtle way to do so! It is really a matter of preference, so the more information you can find out about her preferences, the easier your job will be!
