Depth is an underrated factor in how an oval diamond turns out. Cut too shallow, and the stone spreads wider across the top but risks a stronger bowtie shadow; cut too deep, and that shadow shrinks while the stone’s visible spread shrinks right along with it, so balance is key to getting the best of both.
To give you an idea, a H color, 0.15-carat, IGI-certified, Ideal cut, VS1 clarity lab grown oval shape diamond costs around $168. Carat weight is only one piece of the pricing puzzle in this category; clarity, cut precision, and how evenly the curve was executed all factor into the final number just as much as size does, or ever will, sometimes more.
Clarity and cut work as a team in an oval, more so than in most shapes. A high clarity grade paired with a mediocre cut can still leave visible shadowing, while a well-cut stone squeezes more visual value out of whatever clarity grade it’s given to work with. These factors are always worth taking into account while comparing listings side-by-side across different retailers and price points. On-paper specifications alone aren’t enough to determine how the stone will look in person.
For an oval diamond piece meant to be worn daily, look for a setting where the prongs sit low and tight against the stone’s curve, minimizing the chance of snagging on clothing while still leaving the facets exposed to plenty of light from every angle throughout the day.
