Picking Out the Perfect Diamond Shape and Why It Matters

When choosing the perfect engagement ring, you may become overwhelmed by all the possibilities. You want the ring that is perfect for you, whether it is for its diamond’s brilliance or just because you want a ring that reflects your personality. Whatever your reason, before you go ring hunting, there are some things you should know about why picking the perfect diamond shape is important.

The Cut of the Diamond
Different Diamond Shapes

There are many different diamond shapes to choose from out there, and these shapes are all cut in one of two ways: brilliant cut and step cut. It is important to note here that shape refers to the physical appearance of the diamond, while cut refers to the diamond’s ability to reflect light.

Brilliant-cut diamonds have facets that are shaped either like triangles or kites, and they radiate from the center, giving the diamond lots of fire and brilliance, such as these:

  • Round
  • Princess
  • Radiant
  • Oval
  • Marquise
  • Pear
  • Heart

Step-cut diamonds have facets that are long and narrow and organized in rows, such as these:

  • Emerald
  • Asscher
  • Baguette
  • Trilliant/Trillion

With so many shapes to choose from, you may be thinking that you will never be able to narrow it down. But this guide is here to help you determine which diamond shapes are typically better than others. Diamond shape matters and this guide will tell you why.

Round Cut Diamond Ring

A diamond’s brilliance refers to the amount of light that the diamond reflects towards the viewer. How brilliant a diamond is will depend on how well it is cut. Some diamond shapes are more brilliant or less brilliant than others, and this can affect how much they cost.

Emerald shaped diamonds, for example, have fewer facets to reflect light and can appear dull. It is also easier to see imperfections in emerald shaped diamonds than it is in diamonds of other shapes. If you are looking for more brilliance, but a similar shape, the Asscher diamond is a cousin to the Emerald diamond that is more brilliant.

Round diamonds have the most brilliance because they have over 50 facets that reflect light. Princess diamonds don’t reflect as much light as round diamonds, and so they aren’t as brilliant, but they come in a close second. Marquise, pear, and oval diamonds are harder to cut well, so they may not have superb brilliance. But if they are well-cut, they can look flattering.

Knowing how much brilliance you want in your diamond could be a deciding factor in the shape of diamond you end up choosing.

Different Diamond Ring Setting Options

When looking for that perfect ring, another important thing to look at is how many setting options are available for a particular shape. Four settings are the most common: solitaire, side stone, three stone, and pavee, but these settings may not be available for some diamond shapes. If you are doing a custom design, however, setting options may not be as important of an issue.

Round and princess diamonds have the most setting options available to them, but they are particularly well-suited for being the center stone in a multi-stone ring, such as a three stone or side stone setting. Oval, radiant, cushion, and marquise shaped diamonds are also well-suited to be the center stone.

The solitaire setting is pretty much universal to most diamond shapes. It particularly works well for pear, trilliant, and heart shaped diamonds that are otherwise hard to find a setting for that won’t damage the diamond. Trilliant stones are hard to balance with other stones in a multi-stone ring, but they make great accessory stones.

One thing to keep in mind is that some shapes are more difficult to set than others, and the harder a diamond is to set for a jeweler, the more vulnerable it becomes to damage. Trilliant, marquise, princess, and pear shaped diamonds are the hardest shapes for jewelers to set because they have sharp edges and points that make it easy for them to be chipped while being struck.

If the setting of the ring is important to you, then selecting a diamond shape might be easy.

The last thing you need to consider before choosing a shape for your diamond is the price. Some diamond shapes are expensive, so what you are willing to spend will have a significant impact on your decision.

  • Asschers are more rare, making them more expensive and harder to find nice ones
  • Emeralds are not as expensive initially, but can become quite pricey when you pay to increase the clarity (emeralds NEED to have high clarity due to their faceting structure)
  • Round brilliants carry a higher price tag than most diamonds due to high demand and stone loss in the cutting process, however I can often get AMAZING deals for you and there are more options to choose from.
  • Princess shaped diamonds often carry a lower price tag due to less waste in the cutting process
  • Cushions and Ovals can cost less than rounds, but the really nice ones are usually higher.
  • Marquise and Pear shapes have a lower price point than Rounds & Princess Cuts.

When you are looking for the perfect engagement ring, there are so many factors you must consider. There are many setting options, many prices, and many diamond shapes out there, but knowing how all those things react with each other could be the determining factor.
