1, feel the touch
Gems can be identified by their touch. Real gems have good heat and thermal conductivity, and they will feel cold when held in your hand, but this cold feeling will soon disappear, while fake gems feel mild.
Step 2 consider
In addition, gems can also be identified by weighing. Real gems are compact in structure and heavy in proportion, so they have a certain sense of weight when held in the hand, while fake gems are loose in structure and light when held in the hand.
3. Measure hardness
Gemstones can also be identified by testing their hardness. Real gems are generally hard, and you can't mark the surface with a knife. The hardness of fake gemstones is generally relatively small, so you can mark them with a knife.
Gem jewelry maintenance:
1, stored separately in soft jewelry boxes to avoid the collision of different kinds and hardness of gems.
2. Avoid heavy work and strenuous exercise when wearing jewelry.
3, regular cleaning, keep the smoothness of jewelry.
4. After being punched, organic gemstones should not be worn in a hot and humid environment, so as to avoid steam entering the pores and discoloring them.
5, avoid contact with acid and alkali substances, so as not to corrode gems.
6. Avoid scratches, conduct self-inspection on inlaid gem ornaments regularly, and send them to Tongling jewelry store/museum for reinforcement and maintenance in time once problems are found.
