Compare each diamond and the finished pair separately. Record shape, dimensions, carat weight, color, clarity, cut information where applicable, and report details, then inspect setting profile, metal, posts, backs, pair weight, orientation, and condition.
A diamond stud buying guide that reviews each diamond, the pair relationship, grading evidence, settings, posts, backs, metal disclosure, dimensions, and condition.
What this guide covers
- Read each diamond's evidence rather than the total alone.
- Compare the pair under consistent viewing conditions.
- Review the complete mounting and attachment system.
A diamond report does not grade the finished earrings
Evidence boundary
A laboratory report describes the examined diamond and is not an appraisal. It does not certify pair matching, setting work, metal, post and back compatibility, comfort, closure performance, price, or value.
Compare three layers of a diamond stud pair
Each diamond
Review shape, measurements, carat weight, color, clarity, cut information where relevant, treatment or origin disclosure, and report identity.
The visual pair
Compare outline, face-up dimensions, color and clarity appearance, cut response, orientation, and setting height under the same viewing conditions.
The finished earrings
Inspect settings, metal and finish, posts, backs, joins, pair weight, alignment, condition, and any information not covered by the reports.
Read the pair without collapsing its evidence
- 1 — Match records to stones
Confirm which report or disclosure belongs to which diamond and do not extend one stone's result to its partner.
- 2 — Compare like viewing conditions
Look at the pair together under consistent lighting, distance, orientation, and cleanliness without claiming an exact match.
- 3 — Inspect setting profiles
Compare coverage, projection, prongs or bezel, access for care, alignment, and any movement or catching.
- 4 — Operate both backs
Use the intended action, check post and back compatibility, feedback, pressure, wear, and separate parts on each earring.
Diamond stud buying questions
Is total carat weight the same as each diamond's weight?
No. Confirm whether a number is total for the pair or stated for each stone, along with actual dimensions.
Do matching grades guarantee matching appearance?
No. Individual dimensions, cut details, inclusions, color appearance, orientation, settings, and viewing conditions can differ.
Does a report prove the earrings' value?
No. A grading report is not an appraisal and does not evaluate the complete mounting, market price, or value.
