Real freshwater pearl: The color is natural and smooth, with a crystal clear shine emerging from within. Layers of luster can be seen upon careful observation. Tiny natural imperfections may exist as perfect pearls are rare.

Fake pearl: Often looks "too perfect." Crystal-based pearls may appear brighter than real ones with identical shapes and sizes. Shell powder pearls also show unnatural uniformity in luster and shape.

Identification Methods:

• Appearance: Observe the unique natural variations in size and shape.
• Touch: Real pearls feel cold to the touch; fake pearls often feel warm.
• The Bite Test: Gently bite the pearl. A sandy, gritty feeling indicates a real pearl. A smooth surface suggests a crystal or plastic imitation.
