Ruby is a gemstone of any color, with the presence of an asterism effect, in other words, with a shining star in the stone itself.
The ancient Egyptians decorated the images of the gods with such stones. Another ruby is the first of the 12 stones that decorated the high priest's breastplate.
Precious stones are mined in Australia, Brazil and in Asian countries (Thailand, Sri Lanka).
How to keep
The mineral can be cleaned only with soapy water and a soft cloth (cleaning brushes, it is better to avoid). Remember that ruby does not tolerate ultrasonic and steam cleaning;
• Of course, doing household chores (washing, cleaning, cooking) jewelry must be removed.
