Real vs. Fake Pearls: How to Tell if Freshwater Pearls Are Genuine

The short answer: real freshwater pearls feel slightly gritty when rubbed against your teeth, are cool to the touch at first, have tiny surface irregularities, and have a little weight to them. Fake pearls feel glassy-smooth, are room-temperature, look flawlessly identical, and often feel light or plasticky.

5 easy ways to tell real pearls from fake

1. The tooth test

Gently rub the pearl along the biting edge of your front teeth. A real pearl feels slightly gritty or sandy because of its layered nacre. An imitation feels perfectly smooth like glass or plastic.

2. The temperature test

Real pearls are cool to the touch when you first pick them up and warm slowly in your hand. Plastic imitations are already at room temperature and warm up almost instantly.

3. Look closely at the surface

Genuine freshwater pearls have tiny imperfections — minor bumps, ridges or subtle differences in shape and luster from pearl to pearl. Fakes are often too perfect and identical to one another.

4. Check the weight and drill holes

Real pearls usually have a reassuring weight. Around the drill hole, real pearls show a crisp, clean edge, while coated imitations may show flaking or a shiny paint-like ring.

5. Look at the luster

Real pearls have a deep, almost three-dimensional glow with sharp reflections. Fakes tend to look flat, chalky or overly shiny on the surface only.

Frequently asked questions

Do real pearls scratch easily?

Nacre is softer than most gemstones, so pearls can scratch if stored loose with harder jewelry. Store them separately in a soft pouch.

Are lab-grown gemstones fake?

No. Lab-grown gemstones are real gemstones with the same chemistry and sparkle as mined ones — just created in a controlled setting.
