Care

Pearls are not for everyday wear, and one should take care when wearing. Avoid exposure to heat and protect from scratches and harsh blows. Avoid contact with chemicals, especially perfumes, perspiration and hair sprays. To clean, wipe gently with a moist cloth. Never put them in ultrasonic nor clean them with steam. With a moh's hardness of 2.5 - 4 they are very soft and can easily get scrated or dimpled. They do have a good toughness as they rarely break.

 

Major Sources
