Information and advice limits
gemcubes.com provides general educational information about gemstones, minerals, crystal shapes, buying considerations and care. This information is not an individual gemstone identification, laboratory report, monetary appraisal, investment recommendation or medical advice. For a consequential purchase, sale, insurance decision or identification question, consult a qualified gemologist, an appropriate laboratory or an appraiser whose expertise fits the task.
Photographs, color, shape and simple scratch tests cannot conclusively identify a specimen. A cube-shaped object may be naturally formed or carved; its shape alone does not establish its mineral species. Appearance also does not establish geographic origin, treatment status, ethical sourcing or value. Identification and treatment detection may require additional testing, and an identification report is not necessarily a quality grade or appraisal.
Care must suit the material, its treatments and any jewelry setting. Do not assume that ultrasonic cleaning, steam, heat or chemical cleaners are safe for every gemstone. If identity or treatment status is uncertain, seek professional advice before cleaning. Avoid destructive home tests, ingestion, crystal-water preparations and activities that create hazardous mineral dust or involve dangerous chemicals. Claims about crystal healing should not be treated as established medical evidence or used to delay healthcare.
Accuracy and corrections
Our editorial aim is to use gemological laboratory publications, museum resources and peer-reviewed mineralogical research, while distinguishing established evidence from trade terminology, cultural traditions and interpretation. This aim is not a claim that every page has received professional review or that our contributors hold gemological credentials. Content may contain errors, omissions or outdated information, particularly where treatment detection, laboratory capabilities and marketplace terminology change.
Check important claims against current authoritative sources before acting. Our correction policy is to assess supporting evidence and visibly note material corrections; this does not guarantee an immediate review or response. The publisher’s identity, team credentials and a verified correction-reporting method are not publicly specified. Consult our Contact page for any published contact details, without assuming that a particular submission or response service is available.
External links and images
External links are offered for further reading, not as certification of a seller, product or service. A reference to a laboratory or museum does not establish an affiliation with gemcubes.com. External pages can change, and their claims, terms and commercial offers should be evaluated independently before you rely on them.
Photographs and diagrams can explain features but cannot authenticate your specimen. Lighting, processing, scale and display settings can affect apparent color and detail; an illustrative image may not represent a particular item for sale. Our editorial aim is to identify image sources and check permissions. Public availability does not itself grant permission to reuse an image: consult the applicable license and respect separately credited third-party rights.
Advertising and funding
Our funding sources, advertising arrangements, sponsorships and affiliate relationships are not publicly specified. This uncertainty should not be read as confirmation that the site is either commercially funded or free of commercial relationships. References to products, sellers or services are not proof of independent testing, endorsement or a verified commercial relationship.
Our policy aim is to make relevant commercial interests clear wherever they could affect how readers interpret content. Before buying, check the seller’s treatment disclosures, report details, return terms and the full price independently. Educational comparisons and marketplace descriptions are not guarantees of authenticity, availability, future value or investment returns.
