Modified Brilliant  ·  56–58 Facets

The most efficient diamond in the market — near-round sparkle, greater apparent size per carat, and a meaningful price discount. With one caveat the brands rarely mention.

The oval cut is a modified brilliant — a round brilliant's facet structure stretched into an elongated ellipse. It achieves near-identical light performance to the round while covering significantly more finger surface area per carat, creating a size illusion that makes it one of the most sought-after cuts for buyers seeking maximum visual impact.

Origin

Lazare Kaplan patented the oval brilliant in 1957, adapting the round's 58-facet arrangement to an elliptical girdle without sacrificing optical efficiency. It remained a specialty item for two decades before breaking into mainstream demand in the 1980s. A second surge after 2015 — driven by buyers who discovered near-round brilliance at a meaningful discount — established it permanently as the dominant fancy shape.

On The Hand
Elongating
Most pronounced on shorter or wider hands. The elongated form runs parallel to the finger, visually extending its length. No corners or points — comfortable for daily wear.

Scores reflect ideal-proportion ovals with mild bowtie. A severe bowtie will meaningfully depress brilliance and scintillation — neither appears on any grading report.

Budget
vs. Round Brilliant
−10 to −20%
Structural discount from rough yield — not a quality flag. Same carat, same grade, lower price.
Lab-Grown Oval
−50 to −70%
Highest visual impact per dollar of any major cut. G, VS2, Exc/Exc is the target spec.
What Retailers Won't Tell You
⚠ Bowtie Effect
All ovals show a dark center shadow. No GIA report discloses severity. Never evaluate from a static photo. Watch the stone move on video — retailers photograph ovals to minimize it.
⚠ Crushed Ice Pattern
Some ovals scatter light into small flashes; others show organized bold sparkle. Preference-dependent. Not in any grading report. View face-up before committing.
The Cut Guide  ·  Assessment  ·  Oval Cut
"Near-round sparkle, greater apparent size per carat, consistent price discount. Evaluate the bowtie in person or on video — never from a photograph. For buyers who have done their research, the oval is frequently the correct answer."
