Give the number a visible outline
Use millimeter dimensions to compare diamond scale more clearly than carat alone.
The visualizer offers a direction for shape and face-up size. Screen scale, proportions, and setting can change the impression, so keep the exact stone record involved.
Carat-to-millimeter visualizer
Compare a carat direction with dimensions you know.
Carat is weight, not a face-up measurement. Carat-based dimensions are broad visual approximations. You can also enter the exact length and width from a stone record.No price is estimated here. Compare the exact stone’s dimensions, proportions, and grading information when supplied before choosing.
Directional comparison · not physical screen scale
A clear answer for this stone choice
Accept shape, approximate carat context, or exact length and width and render a labeled directional diamond outline.
This tool compares diamond face-up outlines from shape and millimeter dimensions. Carat context can suggest a starting estimate, but only an exact stone's length and width can represent that stone's face-up outline.
The drawing is directional and never promises physical screen scale. Shape, selected carat context, exact private dimensions, and a catalog stone reference can move into Atelier through a stored entry while free text and uploads stay out of public parameters.

Carat context or exact dimensions
| Decision | What it answers | What remains |
|---|---|---|
| Approximate carat only | Estimated directional dimensions | Do not treat as an exact stone |
| Exact length and width | Directional face-up outline | Still review depth and setting |
| Exact catalog stone | Public measurements plus media | Confirm current availability |
| Uncalibrated screen | Relative comparison | Never physical-scale promise |
Every output labels shape, carat context, length, width, and whether dimensions are estimated or exact.
A size guide, not a promise

Questions worth asking before you decide
Open the question that is already on your mind
Is the preview actual size?
No. It is labeled directional because browser and device scale vary.
Can the tool calculate an exact carat from two dimensions?
No. Depth, shape, proportions, and density context are also relevant.
Will my measurements appear in the URL?
No. Exact dimensions and free text belong in the private stored handoff.
