Quick answer
What should I review when buying a pear-shaped diamond?
For a pear-shaped diamond, prioritize a balanced outline, strong left-right symmetry, an attractive length-to-width ratio, a centered table, a bow-tie that is not overly dark or dominant, and protection for the pointed tip. GIA does not assign an overall cut grade to pear shapes, so actual-stone images/video are important.
Key takeaways
- Pear symmetry is especially important because the two halves should visually mirror each other.
- A bow tie is common; judge its severity rather than demanding zero bow tie.
- Check shoulders, wings, point and centered table.
- The pointed tip needs a protective setting.
- Length-to-width ratio is an appearance preference, not a standalone quality grade.
Start with the outline
Draw an imaginary line from the rounded end through the point. GIA recommends looking for two halves that mirror one another, with balanced shoulders, wings and belly.
Inspect the bow tie
Pear shapes can show a bow-tie pattern across the center. GIA advises looking for a minimal rather than distracting bow tie and viewing the diamond from different angles and lighting conditions.
Check the table and facet balance
An off-center table can make facets on one side appear larger than those on the other. Actual-stone video can reveal imbalance that a report cannot.
Choose the ratio you like
Length-to-width affects whether a pear looks broad or elongated. GIA discusses commonly preferred fancy-shape ratios, but there is no single ratio that makes every pear well cut.
Protect the point
The tip is a vulnerable part of the outline. Choose a setting that protects it, commonly with a V-prong or other appropriate protective design.
What should I check about pear-diamond symmetry and protection?
Combine report and visual evidence
Verify measurements, symmetry, polish, clarity and color on the report, then decide from the actual stone whether the outline and light pattern are attractive.

CaratSignal separates laboratory grading facts from buyer-facing visual evaluation. A grading report documents measured and graded characteristics; it does not guarantee beauty, price, value, eye-clean appearance, or suitability for a particular buyer. Fancy-shape appearance should be assessed from the actual stone, not from a universal proportion formula.
