- Diamond color
- Clarity grade

- Pavé craftsmanship
- Custom design details

Why Can Two 5 Carat Diamond Rings Have Different Prices?
Many customers compare rings only by:
"5 carat"
However, carat weight is only one part of the equation.
A luxury jewelry piece is the combination of:
Diamond + Design + Craftsmanship + Materials
1. Diamond Quality: Color and Clarity
The diamond itself is one of the biggest factors affecting price.
D Color Diamonds
D color represents the highest grade on the traditional colorless diamond scale.
For larger diamonds, color differences become more noticeable because the stone has a larger visual surface.
A D color 5 carat diamond creates an exceptionally bright and icy appearance.
VVS Clarity
VVS clarity means the diamond has extremely small inclusions that are difficult to see even under magnification.
For larger statement diamonds, many buyers prefer higher clarity grades because they want a clean and refined appearance.
MISSISSI focuses on premium lab-grown diamonds with high color and clarity options for luxury engagement ring designs.
2. The Ring Setting Can Dramatically Change the Price
The same 5 carat diamond can look completely different depending on the setting.
Solitaire Setting
A solitaire design places all attention on the center diamond.
Advantages:
- Timeless
- Elegant
- Minimalist
- Highlights diamond size
Hidden Halo Setting
A hidden halo places additional diamonds beneath the center stone.
Advantages:
- Adds side brilliance
- Creates more craftsmanship detail
- Maintains a clean top view
Pavé Diamond Band
A pavé band adds diamonds along the ring shank.
Advantages:
- More sparkle
- More luxurious appearance
- Creates a seamless transition from band to center stone
3. Gold and Platinum Choice
The metal choice also influences the final cost.
14K Gold
Durable and popular for everyday fine jewelry.
18K Gold
Higher gold content and a more luxurious feel.
Platinum PT950
A premium precious metal choice with a naturally white appearance.
Why Are Lab-Grown Diamonds Popular for 5 Carat Rings?

- Larger carat sizes
- Higher color grades
- Higher clarity
- More elaborate settings
For many couples, the appeal is simple:
More size. More quality. More design freedom.
