Emerald maintenance common sense:
(1) Do not touch the acid or alkali, and do not rub against other stones or metals to avoid scratches on the surface of the stone. If you are engaged in manual labor or strenuous exercise, the jewelry should be removed to avoid collision and crack inside the gem.
(2) Good quality gemstones should not stay in the place where the fume is eroded for a long time, so as not to damage the surface gloss of the gemstone.
(3) Avoid high temperatures. It is best to remove the jewelry before soaking for a long time to avoid the temperature of the overheating causing cracks in the interior of the gemstone or expanding the original inner inclusion.
(4) Clean water. Emeralds are often oiled to cover cracks and increase transparency. Therefore, when cleaning emerald jewelry, if you use acid, alkali, alcohol, ether, etc., it will destroy the filling material in the crack and reduce its transparency. Therefore, it is best to wash the emerald jewelry with water. Emerald jewelry cannot be cleaned with ultrasound, as it may cause irreparable damage to the stone.
