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
