Pearl is an ancient organic gem, mainly produced in pearl molluscs and mother-of pearl molluscs; and calcium carbonatecontaining mineral (aragonite) beads, which are produced by endocrine action, are composed of tiny aragonite crystals.
In the gem world, pearls are also listed as lucky stones for the birthday of June, and the commemorative stones for the 13th and 30th anniversary of marriage.
Pearl jewelry is particularly afraid of heat. Overheating temperature will accelerate the decomposition of pearl pearl, so do not expose your pearl jewelry, and also use a soft cloth to wrap pearl jewelry when storing.
