Editorial scope
Luo Wei Su maintains this guide by examining the same evidence a beginner can access before buying: product photographs, stated dimensions, color and clarity, inclusions, texture, luster, apparent weight, treatment wording, seller claims, disclosure details, and return terms.
Working method
Examples are compared side by side by observable features, with seller wording kept separate from what a photograph or simple inspection actually shows. Dyed, coated, treated, reconstructed, synthetic, and glass-like possibilities are considered when the visible evidence or listing language raises them.
Boundary
Color zoning, bubbles, fractures, coating wear, or an unusually uniform surface may help a reader ask better questions, but they cannot by themselves establish identity, origin, authenticity, treatment status, or value. Definitive questions belong with appropriate gemological testing.
Maintenance routine
Published comparisons are revisited when retail labels, treatment disclosures, or example wording need clarification. Corrections and materially clearer examples are incorporated into the relevant page, so the comparison itself stays current rather than relying on detached updates.
Evidence level
This is editorial buying guidance, not a laboratory, appraisal service, or professional gemological opinion. The guide can help readers distinguish an observation from a seller claim and decide what to ask next, while leaving unresolved material questions unresolved.
