Details are as follows:

1, different shapes

Natural pearls have poor roundness due to abnormal non-rolling in the nucleus, while artificial pearls generally have a round nucleus, so they often have fine round beads after formation.

2. Different structures

The inner core of artificial pearls is artificially made, and the inner core of natural pearls is natural quartz sand grains or other substances.

Step 3: Different colors

Natural pearls have delicate texture, soft luster and high transparency (mostly translucent), while artificial pearls are often called "small bags" or "pull" because of their short pearl forming age, loose texture and weak luster.

Extended data:

As a gem, pearls can generally be evaluated and deleted from four aspects:?

1, luster, accounting for 40% of the price; ?

2. Appearance, accounting for 30% of the price; ?

3. Size, accounting for 20% of the price; ?

4. Color, accounting for10% of the price;

Pearl luster plays an extremely important role in the evaluation of pearls and is the key to determine the quality of pearls. Pearls can be roughly divided into three types according to the strength of luster:?

1, strong luster: it appears in the first-class pearls, and the pearl surface is crystal clear and moist, with clear rainbows and visible objects.

2. Medium luster: It appears in secondary pearls, and the surface of pearls is basically transparent, and objects can be seen or partially seen.

3. Weak luster: It appears in tertiary pearls, and the pearl surface is pearlescent or weak pearlescent.
