Emerald is known as the king of emeralds and is a very precious gem (the birthstone of May).
(1) Do not touch acid and alkali [3], and do not rub it with other precious stones or metals to prevent the surface of the gemstone from being scratched. If you are engaged in manual labor or strenuous exercise, you should remove the jewelry so that it will not be impacted and cause cracks inside the stone.
(2) Gemstones with good quality should not stay in the smoked place for a long time, so as to avoid damage to the surface gloss of the gemstones.
(c) Avoid high temperatures. It is best to remove the jewelry before soaking for a long time so as to avoid overheating the temperature to cause cracks in the interior of the gemstone or enlarge the original internal inclusion body.
(d) clean water. Emeralds are often treated with oil immersion to cover up cracks and increase transparency. Therefore, when the emerald jewelry is cleaned, the use of acids, alkalis, alcohols, etc. will destroy the filling material in the feathers and reduce its transparency. Therefore, it is best to wash the emerald jewelry with clean water. Emerald jewelry cannot be cleaned with ultrasonics, or it may cause irreparable damage to the gemstone.
