Hi David,

    If you have seen what you thought to be synthetic alexandrite in
    pieces from the '20s or even the '50s you were seeing  either
    synthetic simulants, probably corundum, or natural alexandrite. As
    you correctly state, it's unlikely someone would lose track of a
    stone as valuable as natural alexandrite has always been, so they
    were probably the former. The first synthetic alexandrite was
    produced, by the flux fusion process, in the early 1970s.
