FREQUENTLY ASKED QUESTIONS

How should buyers approach gemstones with undetermined treatment status?

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.

Why might gemstones have undetermined treatment status?

Some precious stones enter the market through estate sales or vintage collections where treatment records were never maintained or have been lost over time. Certain treatment detection technologies have evolved significantly, making definitive identification of older enhancement methods occasionally inconclusive. Sometimes the stone’s specific characteristics make absolute determination technically challenging even with advanced laboratory equipment, requiring conservative classification despite potentially being completely natural.

Can undetermined treatment stones be good investments?

With appropriate pricing reflecting their uncertain status, these gemstones can represent excellent value, particularly when their appearance suggests potential natural origin. GIA certification helps establish their fundamental authenticity even when specific treatment history remains inconclusive. For collectors primarily concerned with a stone’s aesthetic quality and current appearance rather than its technical history, these precious stones often provide exceptional beauty at significantly reduced cost compared to confirmed untreated specimens.
