Top Diamond Cuts for Engagement Rings

Top Diamond Cuts for Engagement Rings

Diamond cut is one the most noticeable of the “4 C’s of Diamonds” as the cut affects the overall shape and look of the diamond.

Each and every facet and angle cut into the diamond stone affects how light is refracted and reflected – what we like to refer to as the sparkle or bling.

In this Keezing Kreation blog post we’ll make it easy for you to understand the differences between the most popular diamond cuts and shapes so you can choose the perfect center diamond for your stunning custom diamond engagement ring!

Round Diamonds (“Brilliant Diamonds”)

(The most popular diamond cut!)

Round diamonds first became popular in 1919 when the publication of Marcel Tolkowsky’s “diamond design” came out. The round diamond is considered to be the most popular and researched type of diamond on the market. For almost one hundred years diamond cutters have been using theories of light to discover and perfect the brilliance of the round diamond.

Key point of interest:

  • The round diamond provides more flexibility for balancing cut, color, and clarity grades.
  • All round diamonds are brilliant cut, meaning they have 58 facets.
  • Round diamond engagement rings have been popular for decades! Be sure to check out our very own custom designed Matty engagement ring.

Princess Cut Diamonds

(The second most popular diamond cut!)

Created in 1979, the princess cut diamond of the fanciest cut and a popular choice for diamond engagement rings. This is the second more popular type of diamond cut. The shape of the princess cut diamond looks like an upside down pyramid.

Key point of interest:

  • Princess cuts are usually more affordable than round diamonds because it is able to retain about 80% of the rough diamond opposed to the 50% of the rough diamond retained by a round diamond cut.
  • Originally a square cut, most princess cut diamonds are actually slightly rectangular.
  • Of all the square cut diamond the princess cut comes the closest to the round cut in sparkle and brilliance.

Marquise Diamonds

The marquise cut diamond is curvy oblong shaped diamond (often called “boat-shaped”) and is very flattering and recognizable. The Marquise cut diamond first originated in the court of King Louis XIV of France.

Key point of interest:

  • Symmetry is very important, even the slightest off setting can completely ruin the diamond.
  • The diamonds are set in prongs to protect the two points.
  • For a larger marquise stone the color may appear slightly darker at the points.

Oval Diamonds

Due to their elongated shape oval diamonds tend to appear larger and slimmer. An oval cut diamond is great for the customer that likes a round shaped diamond but with a twist. The oval diamond cut is highly recommended for women with smaller hands and shorter fingers because of its elongating effect.

Key point of interest:

  • The clarity and color is much more important in oval shaped diamonds than in round cut diamonds.
  • Faults are much easier to spot and more difficult to hide in the setting of oval diamonds.
  • The oval is elongated enough to be different from the round, but not to be confused with the marquise cut.

Pear Diamonds (“Tear Drop”)

The pear shaped diamond or tear drop is a combination of the round and marquise cut diamond. The perfectly shaped pear diamond is hard to come by – many are too short, too long, or too rounded on the side. But when you come across that perfect pear cut diamond, it is highly versatile and can be used as a center stone or accent stone on any piece of jewelry.

Key point of interest:

  • Due to its shape, the pear shaped diamond has an effect of making your fingers appear longer and slimmer.
  • They create the sparkle of a round shaped diamond, only occasionally will they have a dark spot in the rounded half of the diamond.
  • The most common way to wear the pear shaped diamond is with the tip pointing your finger nails.

Heart Shaped Diamonds

Many people are drawn to the novelty of a heart shaped diamond to symbolize love – particularly for diamond engagement rings! The heart cut diamond is basically a pear shaped diamond with a cleft at the top. Many people refer to the heart diamond as a “fancy cut” diamond and colored heart shaped diamonds are very popular.

Key point of interest:

  • Symmetry is extremely important with the heart shape diamond cut since you want to have the two halves of the heart identical.
  • Heart diamonds come in a variety of narrow to flat to suit your personal preference.
  • The color and clarity can be subjective and most people prefer an ever so slightly warmer tone.

Emerald Diamonds

The emerald cut diamond produces a hall of mirrors effect instead of the sparkle of a brilliant cut diamond. Originally drawn from the cut for emerald stones the emerald cut is now also popular for diamonds. You will find emerald diamonds range from square to long narrow rectangles.

Key point of interest:

  • The main body color is easier to see in the emerald cut due to the larger facets.
  • Emerald cut diamonds provide a unique vintage feel that’s perfect for an engagement ring.

Trillion Diamonds (Triangular Diamonds)

Once a trademark cut developed by Henry Meyer Diamond Company in 1978, the triangular brilliants (also known as Trillions or Trilliants) are three equally straight and slightly curved sides. Trillion diamonds are often seen as side stones for other fancy shapes but also create a stunning centerpiece when made the focal point of an engagement ring.

Key point of interest:

  • When compared to a round cut diamond of equal carat, the trillion cut diamond will look larger.
  • Trillion diamonds are often found with shallow depth percentage and as a result may not have enough depth to reflect as much light and create as much sparkle as round diamonds.
