Real Freshwater Pearl: The appearance is natural and smooth with a shine originating from the inner layers. It looks crystal clear. Under careful observation, the luster is layered. Minor natural dots may exist as perfect pearls are extremely rare.

Fake Pearl: Often made of crystal or shell powder. They may look more "perfect" or brighter than real pearls, but lack the unique natural variation in size and shape.

Testing Methods:

• ✔ Touch: Real pearls feel cold to the touch; fakes often feel warm.
• ✔ Bite Test: Biting a real pearl gives a slightly sandy feeling. Plastic fakes will have holes or show damage, while crystal balls are too hard to bite.
