Ruby and sapphire are famous precious gems. Because of their hardness, they are second only to diamonds, and their colors are magnificent, which is very popular among people. Rubies, sapphires, diamonds, emeralds (gold emerald cat eyes) are collectively known as the world's four (five) large precious stones. Red and sapphire are two different gemstone species of corundum minerals, named after red and blue. In fact, in addition to red sapphire, corundum has many other colors, and other gem-quality corundums of different colors are also collectively referred to as sapphire, such as yellow sapphire, green sapphire and colorless sapphire. Red sapphire is second only to diamonds in prestige. Because it belongs to the same family, it is called "sister gem".
Maintenance of rubies and sapphires
â— Gemstone jewellery of different types and hardness should be placed separately to avoid mutual friction.
â— Avoid high temperature, exposure or sudden cooling
â— Avoid contact with acid and bismuth solutions. For example, wearing diamonds to swim in the pool to prevent the chlorine in the pool from decomposing jewelry.
â— Regular cleaning to maintain the original light of the diamond. Since diamonds and precious stones are very attractive to oil, it is best to clean them once a week. When jewelry is not worn, it must be cleaned and then stored. Otherwise, dust and oil will accumulate in all corners of the jewelry, seriously affecting its brilliance and even causing the gem to loosen and fall off.
â— Think twice before putting the gem into the ultrasonic cleaner. If it is used too frequently, it is easy for the small drill to withstand multiple shocks and loose or even fall.
â—Opacity gems such as lapis lazuli, turquoise, and malachite require special care. Never use an ultrasonic cleaner, not a chemical method. Because these stones are porous and can absorb chemicals and even soaps. It should only be wiped gently with a damp cloth.
