Choosing a solitaire
The stone is everything
With no side stones to distract, the cut, color and clarity of the single diamond are on full display. Cut matters most: an ideal cut round or a well proportioned fancy shape will look brilliant at any carat weight.
Prongs or bezel
Four prongs show the most diamond and give a classic look. Six prongs add security and a softer outline. A bezel wraps the stone in metal, which protects it completely and suits active lifestyles, at the cost of a little light.
Profile
A high setting lifts the stone and lets in more light from the side. A low or cathedral setting keeps the stone closer to the finger, catching less on gloves and pockets. Check the profile in the 360 degree video.
Band width
A slim band of around 1.8 mm makes the stone look larger and pairs neatly with a wedding band. A wider band feels sturdier and suits larger stones.
Why lab grown for a solitaire
Because a solitaire's value is almost entirely in the stone, the lower price per carat of lab diamonds goes further here than in any other setting. You can choose a larger stone, higher grades, or both, for the same budget.

Lab Grown Solitaire Engagement Rings: frequently asked questions
What is a solitaire ring?
A ring with a single center diamond and no other stones on the head or band. It is the most classic engagement ring style and keeps all attention on the main stone.
Four prongs or six prongs?
Four prongs show more of the diamond and give a slightly squarer outline to a round. Six prongs hold the stone more securely and give a rounder outline. Both are excellent choices.
Does a solitaire make the diamond look smaller?
No. With nothing around it, the stone's true size is easy to see. A slim band makes it look larger by contrast.
How much does a solitaire lab diamond ring cost?
The typical complete ring here costs about $1,430, with most between $1,270 and $1,565. Because the setting is simple, most of the budget goes into the stone.
Is a solitaire good for everyday wear?
Yes. With no small stones to lose, a solitaire is low maintenance. Choose a low cathedral or basket setting if you want the stone to sit closer to the finger.
