When shopping for gold oval engagement rings, it’s easy to focus on carat weight, clarity, and color. But there’s one set of metrics that often gets overlooked—depth and table percentages. These two factors significantly influence how your diamond looks and sparkles. Understanding them can help you choose a more brilliant, well-proportioned oval diamond.
At KRK Jewels, we believe every customer should feel confident in their purchase. Here’s what you need to know about depth and table percentages in oval diamond rings.
What Are Depth and Table Percentages?
- Depth Percentage is the ratio of the diamond’s total depth (from the table to the culet) to its width.
- Table Percentage is the ratio of the table (the flat top surface of the diamond) to the diamond’s width.
Both are expressed as percentages and found on the diamond’s grading report.
Ideal Depth and Table Percentages for Oval Diamonds
For oval diamonds, the ideal range may vary slightly based on personal preference, but here’s a general guideline:
- Ideal Table Percentage: 53% to 63%
- Ideal Depth Percentage: 58% to 63%
These ranges help ensure the diamond reflects light properly, maximizing brilliance and minimizing undesirable effects like the bow-tie effect—a dark shadow across the center of poorly cut oval diamonds.
Why These Percentages Matter
- Light Performance
A well-balanced depth and table percentage allow for optimal light reflection, giving your diamond its signature sparkle. - Appearance
Too shallow or too deep a depth can make the diamond appear smaller or dull. Likewise, a large table might flatten the diamond’s appearance, while a small one can make it look lifeless. - Avoiding the Bow-Tie Effect
While the bow-tie is common in oval cuts, the right depth and table proportions can reduce its visibility, leading to a more evenly lit stone.
Common Pitfalls to Avoid
- Too Shallow (<57% depth): May appear larger face-up but sacrifices sparkle and depth of brilliance.
- Too Deep (>64% depth): May look smaller than its carat weight and appear dark in the center.
- Oversized Table (>65%): Can reduce fire and brilliance, making the diamond look glassy.
Always review HD videos or 360° imagery when possible, and if buying online, request expert guidance from trusted jewelers like KRK Jewels.
