Buyers can feel confident purchasing alexandrite with undocumented provenance by relying on comprehensive gemological certification from reputable laboratories. These conflict-free stones undergo testing to verify their natural origin and genuine color-change properties. Reputable dealers provide documentation of the gem’s physical characteristics that confirm authenticity regardless of mining location. The stone’s objective qualities—color change, clarity, and cut—ultimately determine its true value and should be the primary considerations when making a purchase decision.
