The goods sold by Lin Daiyu's jewelry are relatively cheap, some are fake, and some are real after buying them.

The method of distinguishing true and false jewels:

1, see transparency: transparency can be used to understand the quality of gems. Generally speaking, the higher the transparency of the same gem, the more precious it is.

2, look at the luster: the luster of a gem is an important basis for naked eye identification, and a satisfactory refractive range can be roughly judged. Gloss is determined by refractive index and smoothness of polished surface.

3. Observation of inclusions: Observing the characteristics of inclusions in transparent gemstones with a magnifying glass of 10 times is the most reliable way to distinguish natural and artificial products.

4. Look at dispersion: in transparent color-changing gemstones, dispersion intensity can provide important clues for identification. Only diamonds, artificial cubic zirconia, zircon, rutile, garnet and cassiterite can be seen with the naked eye.

5. Look at fracture and cleavage: What luster is fracture and fracture surface, which is particularly important for identifying some gems. The stones with glass luster are mostly conchoidal fracture, while the translucent and opaque jade are mostly granular and hackly fracture.

6. Look at the color-changing effect: the color-changing effect refers to some gem varieties containing chromium or vanadium. Under the irradiation of different light sources, gems show different colors. For example, emerald containing chromium is green under sunlight and red under incandescent lamp, so it is also called metamorphic rock.

7. Look at the red flash effect: The red flash effect refers to the phenomenon that when a blue or green gem containing chromium, vanadium or cobalt glows in the dark, its body color is accompanied by red flash.
