How to choose high quality emeralds
Look for keywords that indicate origin.
" created, " " lab created, " " laboratory grown " or " simulated " are keywords that indicate the emerald is synthetic, not natural. " chatham " emeralds are also man-made.
Be wary of the way a seller uses the word " genuine. " created emeralds are indeed genuine synthetic emeralds, not genuine natural emeralds.
