of the enchanting beauty of pearls come from their uniqueness: no
two pearls are alike. Nature rarely replicates its creations; pearls
are seldom perfect and identical. In other words, if a strand of
pearls present with no imperfections it is likely an imitation.
To further investigate:
Tooth test: although not sanitary,
lightly rub pearls against the biting edge of your upper teeth.
Real pearls will feel gritty and sandy whereas imitation pearls
are likely to feel smooth.
Flaw test: if pearls appear flawless,
they may be an imitation. Freshwater pearls are rarely perfect,
hence their unique beauty.
Heaviness test: bounce the pearls
in the cup of your hand. Unless the imitations pearls have solid
glass beads, imitation pearls feel lighter than natural pearls.
Matching test: look at the virtues
of pearls described above. Imitations are often perfectly matched.
