Approach these stones with appropriate caution but recognize they may represent extraordinary value opportunities if properly evaluated. Always negotiate prices reflecting the uncertainty, typically 20-30% below comparable stones with confirmed treatment status. Natural gemstones with undetermined treatment history should be purchased from reputable dealers offering generous return policies and accompanied by independent laboratory examination whenever possible.
