Normalize the evidence before comparing: the same material categories, compatible report fields, consistent viewing conditions, and explicit unknowns. The result records tradeoffs; it does not calculate a winner.

A no-score comparison worksheet that keeps identity, reports, dimensions, quality fields, durability, observation, setting, and commercial facts in separate rows for two stones.

What this guide covers

Gather compatible identity, report, measurement, treatment, observation, and setting evidence for both stones.
Compare one dimension at a time under the same stated conditions and preserve every unknown.
Name personal priorities, then verify live identity, condition, price, availability, and terms outside the worksheet.

Inputs required for both stones

If evidence is incompatible or missing, mark it visibly instead of filling the gap or assigning points.

Material identity, natural or laboratory-grown status, simulant status, treatments, source, and report details
Shape, cutting style, weight, millimeter dimensions, applicable quality fields, and report comments
Loose or mounted state, date, lighting, distance, orientation, magnification, photographs, and direct observations
Intended setting and wear, documented durability and care, current price, availability, seller terms, and open questions

Use a no-score method

1 — Normalize evidence
Confirm that names, report services, and fields are compatible, with missing data left visible.
2 — Normalize observation
Use the same practical lighting, distance, orientation, magnification, and mounting state where possible.
3 — Describe tradeoffs
Keep each dimension separate and let the buyer state priorities without a hidden weight or overall winner.

A comparison record, not a ranking

Evidence quality

Working result: Compatible fields, sources, dates, and visible gaps
Boundary: No silent normalization or report verification

Observed differences

Working result: Separate dimensions and same-condition notes
Boundary: No composite score or universal preference

Decision gaps

Working result: Identity, setting, price, stock, and policy checks
Boundary: No recommendation, reservation, or purchase action
