Diamonds come in all shapes and sizes, each possessing its own allure. Among the many unique measurements in the world of gemstones, the 8.17×5.64×3.52 diamond is a particularly striking example. Its precise proportions not only contribute to its visual appeal but also impact its light performance and desirability. Whether you’re exploring options for a custom engagement ring or simply intrigued by unusual diamonds, understanding this dimension is an important first step.
In this article, you’ll discover why the 8.17×5.64×3.52 diamond deserves attention, what to look for in terms of quality, and how to ensure your purchase delivers both beauty and long-term value.
Decoding the Dimensions of an 8.17×5.64×3.52 Diamond
Every diamond’s allure begins with its measurements. The three figures—length, width, and depth—define the stone’s face-up size and silhouette:
-
Length (8.17 mm): Determines how long the diamond appears.
-
Width (5.64 mm): Affects the overall spread and finger coverage.
-
Depth (3.52 mm): Influences how well the stone reflects light.
The 8.17×5.64×3.52 proportions are often associated with elongated cuts such as oval, marquise, or radiant shapes. These cuts are known for maximizing surface area relative to carat weight, allowing the diamond to look larger when set in a ring or pendant.
Reasons to Consider an 8.17×5.64×3.52 Diamond
1. Distinctive Appearance
An 8.17×5.64×3.52 diamond has a graceful elongated shape that draws the eye. Compared to round cuts of similar weight, this dimension offers a more slender profile, which can flatter the hand when set in an engagement ring.
2. Enhanced Finger Coverage
Because of its extended length and moderate width, this diamond appears substantial when worn. For those who prefer the look of a larger stone without necessarily increasing carat size, this proportion offers excellent visual impact.
3. Versatile Setting Options
Whether you envision a solitaire, halo, or vintage-inspired design, this size adapts beautifully to many styles. It can be mounted vertically for an elegant look or set horizontally for a modern twist.
Understanding the Role of Carat Weight
Carat weight alone doesn’t determine a diamond’s appearance. Instead, actual millimeter measurements—like 8.17×5.64×3.52—show how much of the stone is visible once it’s set. For example, two diamonds of the same weight can look dramatically different if one has a deeper pavilion and less surface area.
This is why jewelers often recommend reviewing both carat and dimensions together. A diamond of this size typically weighs between 1.2 and 1.5 carats, depending on shape and cut proportions. Always ask for a grading report to see the complete specifications.
The Importance of Cut Quality
No matter the measurements, a diamond’s cut quality is critical to its brilliance. Even a well-sized diamond can look dull if the cut isn’t properly executed. For an 8.17×5.64×3.52 diamond, aim for the following:
-
Excellent or Very Good symmetry and polish: These grades indicate crisp facet alignment and a smooth finish.
-
Balanced depth percentage: The ideal depth for elongated shapes usually falls around 60–68%.
-
Even light return: Well-cut diamonds sparkle under different lighting conditions and show minimal dark areas.
Reviewing videos or images of the actual stone can help you assess performance before purchasing.
Evaluating Clarity and Color
Because an elongated shape often has a larger face-up area, inclusions can be easier to spot. For this reason, clarity is especially important.
Clarity Tips:
-
Choose VS2 clarity or better to reduce the risk of visible imperfections.
-
Inspect the diamond under magnification or request detailed photos.
Color Considerations:
-
D–F color grades are prized for their icy whiteness.
-
G–H grades offer excellent value with a near-colorless appearance.
-
Consider how the setting metal (white, yellow, or rose gold) can affect perceived color.
Popular Settings for the 8.17×5.64×3.52 Diamond
The way you set a diamond of this dimension makes a big difference in its overall look. Here are three popular options:
-
Solitaire Prong Setting: A timeless choice that showcases the diamond’s shape and brilliance.
-
Halo Setting: Adds extra sparkle with a ring of small diamonds, making the center stone look even larger.
-
Bezel Setting: Surrounds the gem in metal for a sleek, modern style while protecting the edges.
Because the 8.17×5.64×3.52 dimension is elongated, jewelers often use V-shaped prongs to secure pointed ends if applicable (as with marquise or pear cuts).
How to Shop for an 8.17×5.64×3.52 Diamond
When buying a diamond with this measurement, consider these guidelines:
-
Request a Certificate: Always choose stones with a GIA or AGS grading report confirming cut, color, clarity, and proportions.
-
Review Imagery: Look at videos or photos to see how the diamond performs in different lighting.
-
Compare Options: Even within the same size, light performance and clarity can vary.
-
Set a Budget: Allocate more budget toward cut and clarity rather than carat alone.
-
Work With a Reputable Jeweler: Select a retailer with transparent policies, fair pricing, and return options.
Care and Maintenance
Diamonds are extremely durable but not indestructible. To keep your 8.17×5.64×3.52 diamond looking brilliant:
-
Clean it regularly with warm water, mild soap, and a soft brush.
-
Store it separately to avoid scratching other pieces.
-
Schedule professional inspections at least once a year to ensure prongs remain secure.
