Why Marquise Diamonds Need Special Setting Design
A marquise has two pointed tips that require dedicated protection.
Explore a MISSISSI Marquise Lab-Grown Diamond Engagement Ring.
Why a Marquise Can Look Large for Its Carat Weight
Its elongated outline creates strong north-to-south finger coverage.
What Does a 1.95 vs 2.05 Ratio Look Like?
Around 1.95 tends to look fuller; around 2.05 tends to look more elongated. The actual stone should still be judged visually.
What Is a Good Bow Tie?
Look for contrast that changes as the stone moves and does not remain excessively dark.
Why Six Prongs?
A six-prong design can provide more contact points while preserving the elongated outline when positioned carefully.
Why V-Prongs Matter at the Tips
V-style protection helps secure the two pointed ends without visually shortening the stone.
What Is a Tulip Basket?
A tulip basket uses curved supports that rise toward the center stone, creating a refined architectural side profile.
Can a Tulip Basket Work With a Hidden Halo?
Yes. The halo can be integrated beneath the center while keeping the top view focused on the marquise.
Why Cathedral Shoulders Can Improve the Design
Cathedral shoulders create a stronger visual and structural connection between the shank and center setting.
Why a 2mm Band Is a Practical Starting Point
Around 2mm can still look refined while giving a large center more support than an ultra-thin band.
How Do You Make the Ring Wedding-Band Friendly?
Plan basket width, setting height, hidden-halo position and cathedral profile before production.
VS1 or VVS?
VS1 can be an excellent target if eye-clean. VVS may appeal to buyers who prefer a higher paper grade.
D, E or F Color?
All three fall in a high color range, and visible differences may be subtle once mounted.
Why CAD Is Essential
Review top view, side view and wedding-band clearance before production.
