Compare gemstone outlines with documented millimeter dimensions and name the cutting style separately. Screen scale, depth, faceting, transparency, color, and setting context mean the drawing cannot reproduce the exact stone.

A relative gemstone silhouette worksheet that separates outline, cutting style, length, width, depth, ratio, and mounting context without turning a digital drawing into identity or quality evidence.

What this guide covers

Record the outline, cutting style, millimeter dimensions, and evidence source for each gem.
Place shapes on one relative scale while keeping depth and visual variables visible.
Return to the exact stone, report, photographs, and setting review before drawing any item conclusion.

Name the gemstone dimensions

Use documented measurements; leave identity, treatment, and quality fields outside an outline comparison.

Outline shape and cutting style as separate names, plus material identity only when documented
Length, width, depth, and ratio in millimeters with source, date, and loose or mounted state
Transparency, color zoning, pleochroism, phenomena, and faceting notes only when evidenced
Display calibration status, image conditions, intended setting, and questions that require direct review

Build a relative silhouette record

1 — Normalize the dimensions
Keep length, width, and depth in millimeters and do not derive missing values from weight or a photograph.
2 — Draw only the outline
Compare silhouettes on one labeled relative scale without simulating facets, color, brilliance, or setting fit.
3 — Attach the open variables
Carry depth, cut, image, identity, treatment, condition, and mounting questions beside the drawing.

What a silhouette can and cannot show

Outline

Working result: Relative length-to-width shape
Boundary: Not a complete cutting-style or quality view

Scale

Working result: Shared digital comparison basis
Boundary: Not guaranteed physical size or color

Stone record

Working result: Documented dimensions plus unresolved fields
Boundary: No identity, treatment, fit, grade, or value result

The gemstone itself remains the source
