Replacement Matching
For replacement purchasing, the existing diamond's physical dimensions can be used alongside its grading information to define the required specification.
Relevant matching criteria include:
- Carat weight
- Diameter
- Depth
- Color
- Clarity
- Cutting style
- Certification
Where an existing stone is available for reference, its measured dimensions can help narrow the replacement requirement.
Setting Compatibility
For a new or existing setting, the stone's measured dimensions provide the reference for dimensional checking.
For this individual diamond:
- Diameter: 6.39–6.43 mm
- Depth: 3.96 mm
The setting should be checked against the actual measurements and construction requirements before the stone is selected.

FAQ
Q: A replacement diamond is needed for an existing ring. Which measurements matter most?
A: The existing stone's diameter and depth are useful starting points, together with its carat weight, color, clarity, and cutting style.
Q: If two 1 ct Round diamonds have the same carat weight, will their dimensions necessarily be the same?
A: No. Carat weight alone does not define the physical dimensions of a Round diamond. Diameter and depth should also be considered when a specific replacement or setting fit is required.
Q: How can an existing setting be checked against a replacement stone?
A: Compare the setting's stone dimensions and construction with the replacement diamond's measured diameter and depth. For this stone, the dimensional reference is 6.39–6.43 × 3.96 mm.
