Jewellery VideoSynthetic vs natural gems — the difference that matters
Same chemistry, different origin story — and a third category pretending to be either.
Three words decide the gem market's honesty, and buyers confuse them
constantly.
Natural — mined, formed by geology.
Synthetic — SAME chemistry and crystal structure as natural, but grown
by people: lab diamonds, flame-fusion corundum, hydrothermal emerald.
Legitimate, often beautiful, priced accordingly — but must be DISCLOSED as
synthetic. Telling them apart is gemmology's core skill (inclusions,
growth structures).
Imitation — a different material pretending to the eye: CZ for diamond,
glass for everything. Fine for fashion when named; fraud when not.
The buyer's protections — buy from sellers who state origin in writing;
ask "is this natural, treated, or synthetic?" and watch whether the answer
is comfortable; remember that price rarely surprises after disclosure —
it surprises AFTER the fact.
Identification of all three categories is the heart of the
gemmology course and its hands-on identification course.
