What makes a beautiful oval
The bow tie
Every oval shows a darker band across its middle, called a bow tie, where light escapes. In a well cut stone it is faint and shifts as the stone moves; a strong, fixed shadow is the most common flaw in the shape. The 360 degree video is the best way to judge it: watch the middle of the stone as it rotates.
Ratio
The length to width ratio sets the outline. Around 1.35 looks balanced and classic; around 1.50 looks long and slender. Neither is better, but most buyers prefer something between the two.
Color
Ovals can show a little more color at their tips than rounds. F or G color keeps the stone looking white in platinum and white gold; in yellow or rose gold, H can look lovely.
Clarity
Brilliant faceting hides small inclusions well, so VS2 or even SI1 can be eye clean. Check the video for anything visible near the center.
Pairing a setting with an oval
A solitaire shows off the outline and is timeless. A hidden halo adds sparkle in profile while keeping the top view clean. A halo makes the stone look larger still. East west settings turn the oval sideways for a modern look. Three stone designs with tapered baguettes or small pears frame it beautifully.

Oval Lab Grown Diamond Engagement Rings: frequently asked questions
Why are oval diamonds so popular?
An oval faces up larger than a round of the same weight, slims the finger and keeps much of the round's brilliance. It suits almost every setting style.
What is a bow tie in an oval diamond?
A dark, bow tie shaped shadow across the middle of the stone, caused by how light leaks through the center facets. Every oval has some; a good one has a faint bow tie that is barely visible as the stone moves.
What length to width ratio is best?
Between 1.30 and 1.50 is the classic range. Lower ratios look rounder; higher ratios look longer and slimmer. Personal taste decides within that range.
How much does an oval lab grown diamond engagement ring cost?
The typical complete ring here costs about $1,505, with most between $1,340 and $1,755. Carat weight and setting drive the price.
Which setting suits an oval best?
A solitaire shows off the outline; a hidden halo adds side sparkle; a halo makes it look even larger; and three stone designs with pear or tapered side stones create a classic look.
