Oval vs Round Diamonds- Find The Right One for Your Partner!

Knowing the difference between an oval and round diamond is important if you are planning to buy one. A round diamond may give off nice brilliance, but an elongated oval diamond looks more stunning for its elongated shape.

Besides this, several factors make them different from each other and today we will go through each one to learn more about their characteristics and attributes.

Key Difference Between Oval vs Round Diamonds

Shape

Oval Diamonds:

• An oval diamond is a brilliant cut diamond with a long, rounded form resembling an oval. This distinguishes them from round brilliants, which have a perfectly symmetrical form.

• Due to their longer shape, oval diamonds may give the impression of being up to 10-15% bigger than a round diamond of the same carat weight. This expanded look enhances their visual impressiveness.

Round Diamonds:

• Round diamonds are characterized by their perfectly proportioned, perfectly symmetrical, and perfectly outlined circular form, as the name suggests.

• To get the most dazzling effect, cutters strive for precise measurements that allow light to reflect and refract light throughout.

Cut

Oval Diamonds:

• The longer contour of an oval diamond requires precise cutting. The stone’s length is adorned with facets on both sides.

• At some angles, well-polished ovals display a “bow-tie” look of darkening regions. Achieving uniform faceting may reduce this impact.

Round Diamonds:

• For decades, cutters have fine-tuned the round brilliant cut to bring out the most sparkle by adjusting the table size, crown height, pavilion depth, and facet configurations.

• The classic cut and symmetrical shape of round diamonds showcases their brilliance by distributing light evenly over their surface.

Beauty and Appeal

Oval Diamonds:

• Diamonds in an oval form are a contemporary take on the classic round brilliant. Their elongated form is striking, yet they radiate a great deal of light.

• Even when worn as rings, the extended design may give the illusion of smaller, longer fingers. For those seeking a non-conventional look, ovals provide a certain allure.

Round Diamonds:

• As a symbol of everlasting beauty, a round diamond conveys feelings of romance and tradition. They have a timeless style with their design.

• Round diamonds, thanks to their uniform faceting and contour, always sparkle like no other shape.

Cost and Value

Oval Diamonds:

• For the same carat weight, cut grade, and color/clarity ratings, an oval diamond with a good cut would typically cost about 15% to 20% less than a round diamond with an excellent cut. All things considered, they’re a steal at the price.

• Undercutting may make the bow tie effect contrasts in larger oval diamonds (those above 2 carats) more apparent. When contrasted with a perfect round, this might reduce value.

Round Diamonds:

• Round diamonds allow for the most light to pass through and retain more of their worth due to their exceptional symmetry and perfect cutting proportions.

• In comparison to fanciful forms, the resale value of well-cut, high-quality round diamonds is higher because of their iconic status and demand.

Setting Options

Oval Diamonds:

• Since oval diamonds are longer than round ones, their orientation may be vertical, horizontal, or diagonal, depending on the setting and the style you’re going for.

• Halo, solitaire, three-stone, and antique/heirloom settings, such as Art Deco engagement rings, are popular oval settings.

Round Diamonds:

• Because of its perfectly round cut, a round diamond is the most versatile gemstone when it comes to ring designs and settings.

• Round diamonds are very adaptable and may be used as focal points or accent stones in a wide variety of settings, from traditional solitaires to contemporary multi-stone and halo designs.

Bow-Tie Effect Comparison

Oval diamonds:

• When seen from certain angles, oval diamonds often display a bow-tie pattern of shaded regions. This effect is most noticeable when looking at an oval with its top side facing up.

• Over the whole surface of the table, there is a design that looks like a bow tie. The reason for this is that the light return is not evenly distributed due to the oval’s extended cut.

• Careful alignment of the pavilion and crown facets is required for precise cutting to minimize the bow-tie effect. There will always be a certain amount of bright and dark patterning.

Round Diamonds:

• Light reflects off of every surface of a round brilliant diamond thanks to its perfectly symmetrical shape and well-planned arrangement of its facets.

• In properly proportioned round diamond cuts, neither light leakage nor the bow-tie shadow effect can be seen locally.

• Since there is no directionality to create intense light or dark spots, light return is maximized and constant from any angle.

Brilliance and Fire

Oval diamonds:

• Oval diamonds reveal a one-of-a-kind pattern of light and shadow reflected off their lengthy contour, creating a hall-of-mirrors illusion.

• For an oval diamond, the form dictates the use of greater facets on the sides of the stone. In contrast to the kaleidoscopic effect of a round, this may affect fire.

Round diamonds:

• The pavilion facets of a round diamond are arranged in concentric rings, and they serve as little light tunnels, enhancing the brilliance of the diamond as it returns to the table.

• Optimal synchronized light performance is achieved through precisely bezel-and crown-angled facets, which provide unparalleled flash and fire from every aspect.

Optical Precision

Oval diamonds:

• Cutters have a harder time getting the length and breadth of oval diamonds to be uniformly angled for maximum light return since the gems’ facets curve.

• Using specialized imaging techniques like ASET or Idealscope, light leakage in oval diamonds may be mapped to assess their light performance.

Round diamonds:

• With inter-facets angles that are within one degree, round diamonds are ideally the most optically precise and consistent gemstones.

Durability

Oval diamonds:

• The sharp ends of oval diamonds are more prone to chipping when they are hit from the side. Bezel settings provide a layer of defense.

Round diamonds:

• The smooth design with no sharp edges ensures long-term reliability. Better protection from all directions is a feature of round diamonds.

Which Setting Suits Best for Oval vs Round Diamonds?

Oval Diamonds: Best with Vintage-Inspired Settings

Art Deco, Victorian, and halo settings are perfect for oval diamonds because of their retro appeal. The elaborate designs and exquisite filigree craftsmanship complement the oval shape and gracefully expanded facets. 

Set an oval in a halo border to make it shimmer even more and draw attention to its lengthy edge. Engraving and shared prong details allow for optimum light access while highlighting exceptional workmanship, creating a modern but timeless look.

Round Diamond: Best with Solitaire Setting 

Round brilliant diamonds are the most classic and timeless choice for a solitaire engagement ring. Diamond solitaires, which were the first of their kind, are now universally associated with round diamonds due to their characteristic round cut. 

One subtle and beautiful approach to show off a round diamond’s radiance is on a ring made of platinum, white gold, rose gold, or another precious metal with four or six prongs. The round diamond’s intrinsic symmetry makes it an ideal cut for solitaire settings, which draws all attention to the stone without sacrificing the stone’s beauty.

Which Diamond Looks Bigger- Oval or Round?

In terms of optical illusions, diamonds of all shapes and sizes may deceive. In contrast to the more conventional round brilliant cut, the elongated contour of an oval diamond may give the impression of more depth. Do actual, observable size disparities result from this, though?

When compared to round diamonds of the same carat weight, ovals seem bigger when turned face up. Their unusual form usually has a length that is 1.3 to 1.7 times wider than it is long. From above, an oval will seem around 10-15% bigger than a round of the same carat weight due to its elongation.

The size comparison may vary on various factors:

• Table %: The spread area across a deeper round table cut may be increased by making the table wider on an oval.

• Cut quality: The accuracy of the cut determines the final dimensions. A badly cut oval could have a narrower diameter than a well-cut circle.

• Setting: Compared to a bezel setting, prongs that reveal the whole oval seem larger.

Even while it’s not a precise science, most people agree that ovals seem bigger than rounds of the same carat weight. Their shimmering contours provide the impression of maximum depth.

FAQ

What is the key difference between Oval and Round Diamond Shapes?

Unlike round diamonds, which have an asymmetrical, round contour devoid of directional form, oval diamonds have an exquisitely extended spherical outline reminiscent of an oval. In contrast to round diamonds, which have consistent concentric faceting, oval cuts display a higher degree of faceted variation, particularly at the ends of the stone.

Why do round diamonds cost more than oval diamonds?

When compared to rounds of the same cut, color, and clarity grade, well-cut oval diamonds may save you tens to even twenty percent. One carat of oval diamonds of Ideal or Excellent cut grade might save you up to 30% compared to rounds. Reasons for the price discrepancy include the accuracy needed to cut rounds and the fact that demand is lower.

What does the Bow-Tie Effect mean?

From certain angles, oval diamonds may display a shaded outline pattern that looks like a bow tie across their face-up table surface. This phenomenon is called the bow-tie effect. Their large facets cause light to be reflected unevenly, leading to this effect. To make the bow-tie appearance almost invisible, ideal symmetry oval incisions dampen the light’s uneven return.

Which diamond created more sparkle- Round or Oval?

When it comes to brilliance and fire, round diamonds always win out. This is because their cut proportions are so precisely calculated to maximize light return. On the other hand, modern oval diamond cuts use broader facets to boost sparkle within their distinctive outline. Oval radiance is its elongated kind of dazzling.

Which diamond should I choose if I have short fingers- Round or Oval?

Because of their tapered shape, oval diamonds may make short fingers seem longer and thinner. To accentuate shorter fingers, set an oval diamond vertically so its length shows. To prevent the illusion of a shortened look, rounds will centralize the emphasis.

Conclusion 

If you had to choose between oval and round diamonds, oval is a safer bet. Even while it still sparkles wonderfully, the oval’s longer form makes it stand out more. Plus, the effect is breathtaking when the ovals dazzle and glimmer in various light patterns.

You can get a round diamond for less money, which is great since you can use that savings for a better setting. The light that emanates from a round form is stunning, and the flawless symmetry of a round stone is hard to top. Ovals, however, have a unique charm.

The oval shape gives off an extra dose of charm that makes it the right choice but if you are planning on saving money then round is an ideal choice.
