Yes, there are easy ways to tell if pearls are real, primarily the tooth test, where real pearls feel gritty and fake ones smooth, plus checking for natural imperfections, deep luster, cool temperature, and significant weight. Real pearls have subtle surface flaws, a glow from within, feel cool at first, and are heavier than lightweight plastic fakes, while perfect, uniform, warm-feeling beads are usually imitation.
In water, pearls do not float.
Friction Tests:
Hold the pearls in your fingers, and gently rub them against each other. A true pearl will create friction with another due to the grainy, imperfect surface. Fakes, on the other hand, will easily glide past each other due to their artificial coatings.
Microscopic Analysis. A jeweler may also use a microscope to examine the pearl's surface and internal structure. Under magnification, the natural crystalline structure of nacre is visible in real pearls, while fake pearls will lack this texture.
Fake pearls made out of glass or plastic are worth literally nothing.
The most expensive pearl colors are often deep, rich hues like Golden South Sea (especially 24k deep gold), rare Peacock Tahitian (dark green/blue/purple overtones), and intensely pink or pink-overtoned White South Sea pearls, with value heavily depending on rarity, luster, size, and lack of blemishes, rather than just the base color itself. While white and black are common, specific, saturated, and rare overtones within these categories command the highest prices.

Real pearls are normally heavier than the fake ones. Toss them gently up and down in your hand and feel the weight difference.
Harvesting cultured pearls often kills the oyster, as many farms kill the animals after the first harvest for their meat and shell, though some try to recycle them for multiple harvests, while wild pearl harvesting kills thousands of oysters for just a few pearls. While some techniques allow oysters to survive and produce more pearls, especially with skilled intervention, the overall industry often involves stress, harm, and eventual death for most mollusks.
Another way to check if your pearls are real is to submerge them in vinegar. If they are real, the pearls will form bubbles due to the chemical reaction of vinegar acid and calcium carbonate which is the primary chemical that a real pearl is made of.
Imitation pearls might have a magnetic core, but genuine pearls are made from organic material that does not respond to magnets.
Remember to follow the "last on, first off" rule, applying pearls after makeup and lotions. Avoid brushing hair while wearing pearls and remove them before sleeping or showering. Clean them with a damp cloth and store them in a cool, dry place away from sunlight.
