In the market, there are indeed ** lower crystal products, but their authenticity may be questioned to a certain extent. To identify the authenticity of crystals, the following aspects can be considered:
1.Material inspection: Crystals are usually transparent or translucent, with luster and a clear crystal structure. You can take a closer look at the appearance of the crystal to see if it has a natural crystal shape and texture.
2.Temperature sensing: Crystals have good thermal conductivity, so touching the crystal surface with your hands will give you a cooling sensation that man-made materials don't usually have.
3.Optical properties: True crystals can shimmer and change color in sunlight or bright light, due to the refractive and reflective properties of crystals. You can place the crystals in a well-lit area and see if you can see these optical effects.
4.Weight comparison: Real crystals are usually heavier than man-made objects. You can compare the crystal with other objects of the same size to get an idea of its relative weight.
5.Sound test: Gently tap the crystal, real crystal will produce a crisp and pleasant sound, while artificial materials may produce a dull or unusual sound.
It should be noted that the above methods are for reference only and cannot be 100% sure of the authenticity of the crystal. If you have doubts about the authenticity of your crystals, it is recommended that you consult a professional gem appraiser or purchase products from reputable merchants.
