Look within the stone.
Gemological assessment and laboratory coordination to examine identity, treatments, origin evidence, and valuation factors.
Assessment & analysisCharacter before conclusion.
A gemstone's appearance is one part of its assessment. Stratum Gemological coordinates specialist examination and helps clients interpret the resulting evidence. We consider the purpose of the assignment, the specimen, and the available reports before defining an analytical scope and the information needed for a valuation opinion.
Discuss your requirementsSpectroscopic examination
Coordinate appropriate FTIR, Raman, or UV-Vis-NIR testing with specialist laboratories according to the specimen and the questions being investigated.
Inclusions & internal features
Bring microscopic observations into the assessment, including inclusion patterns that may support identification, treatment analysis, or origin interpretation.
Identity & treatment review
Review findings concerning natural or synthetic origin and potential treatments, recording unresolved questions and the limits of the examination.
Valuation context
Bring together measurements, classifications, laboratory findings, and stated valuation assumptions in a report suited to the agreed purpose.
A report with context.
Analytical results depend on the specimen, methods, and reference information available. An assessment should make its limitations explicit; laboratory analysis alone does not establish an exact mine of origin or a future sale price.
