A gemstone report describes the item examined by a laboratory. Read it alongside the actual stone’s details—not as a badge that automatically proves value, spiritual effects or every statement in a product listing.
Start with the issuing laboratory and report number
Identify who issued the report and use that laboratory’s official verification method, where available. For example, GIA Report Check lets you check a GIA report number. This is an example of a laboratory service, not a statement that Horocosmo products have GIA reports.
Read what the report actually identifies
Check the gemstone identity, whether it is described as natural or laboratory-grown, and any treatments reported. GIA’s sample coloured-stone reports illustrate these distinctions. Different report types have different scopes; geographical origin is not automatically part of every identification document.
Match the document to the item
- Compare the description, shape, dimensions and stated weight with the offered stone.
- Check whether a weight refers to the loose stone or to a mounted item.
- Compare the photograph where one is included.
- Ask whether the report covers the exact stone, a sample or a batch.
- Resolve discrepancies before purchasing, rather than assuming two similar-looking stones are interchangeable.
Ratti labels and carat weight
If a listing uses ratti, ask for the actual measured carat weight as well. Do not calculate an exact stone weight from an unspecified ratti convention. A product option label should be reconciled with the item’s measurements and report.
What a report does not establish
A material report does not promise astrological suitability, medical benefits or investment returns. It also does not automatically establish a return right: read the seller’s written policy and ask about any proposed independent recheck before paying.
Questions worth sending to the seller
- Which laboratory issued this report, and can I see the full document?
- Does it cover this exact stone or another sample?
- What are the measured weight, dimensions and disclosed treatments?
- What does the written policy say if the delivered item differs from its description?
Questions before you choose
Is a treated stone automatically fake?
Treatment and identity are different questions. Read exactly what the report says about the material and any detectable treatment, then decide whether that matches the item offered.
Can a verified report number prove I received the same stone?
It verifies the document record. You still need to match the document’s item details to the stone supplied.
Should a report always state geographical origin?
No. Read the report type and scope. An identification report does not necessarily include an origin opinion.
