A Case of Mistaken Identity? - GIA
Garnet usually has fewer inclusions than emerald, but if liquid or two-phase inclusions are present in emerald, they can be an identifying factor. Separating peridot from demantoid garnet is easier if "lilypad" (unique disc-like liquid and gas inclusions found in peridot), are seen under 10x loupe magnification. ...
