Compare Diamond A and Diamond B row by row: first normalize the reports and material disclosures, then keep cut, color, clarity, weight, dimensions, finish, fluorescence, appearance, setting, and live seller facts separate. The worksheet does not score or choose.

A non-interactive local worksheet for comparing two diamonds across normalized report identity, measurements, quality fields, direct observations, setting context, and unresolved commercial facts without calculating a winner.

What this guide covers

Collect compatible report, identity, measurement, observation, setting, and seller-policy inputs for both stones.
Apply the same viewing conditions and record each dimension without converting it to points.
Choose only after naming personal priorities and verifying current item, price, availability, and written terms elsewhere.

Inputs required for both diamonds

Leave a field unknown rather than filling it from an incompatible report, unverified listing, or visual guess.

Material and origin disclosure; issuing laboratory; report type, number, and date
Shape, cutting style, carat weight, and millimeter measurements
Applicable cut grade or no cut grade; table, depth, girdle, culet, symmetry, and polish fields
Color, clarity, plot or comments, fluorescence, and detected treatments
Loose or mounted state; lighting, distance, orientation, magnification, and date of observation
Intended setting, exposed geometry, wear needs, current total price, availability, and written policies

Use a no-score comparison method

1 — Normalize evidence
Confirm that both report fields use compatible definitions and keep unknown or inapplicable entries visible.
2 — Normalize observation
View both stones at the same distance, lighting, orientation, magnification, and mounting state where practical.
3 — Describe, do not score
Record differences in separate rows and let the buyer name which observed tradeoffs matter most.
4 — Verify live facts
Check current identity connection, condition, price, availability, setting, and seller terms through authorized sources before deciding.

The worksheet result keeps dimensions separate

Identity and report

Diamond A: Record verified fields
Diamond B: Record verified fields
Guidance: Flag incompatible, stale, missing, or unverified data instead of harmonizing it silently.

Geometry and finish

Diamond A: Record measurements and applicable fields
Diamond B: Record measurements and applicable fields
Guidance: No single proportion or finish field becomes an overall result.

Color and clarity

Diamond A: Record grades and observed appearance
Diamond B: Record grades and observed appearance
Guidance: Keep laboratory results distinct from the disclosed viewing conditions.

Setting and wear

Diamond A: Record fit and unresolved questions
Diamond B: Record fit and unresolved questions
Guidance: A loose-stone comparison cannot certify the finished piece.

Commercial facts

Diamond A: Verify current seller evidence
Diamond B: Verify current seller evidence
Guidance: The local worksheet contains no live price, stock, reservation, or policy state.

The result is a comparison record, not a recommendation
