There’s info about gemstones; Hardness on Mohs’s scale, origin, colors, jewelry (as in, what kind on jewelries are best for that specific gemstone), and cleaning.
If there is ˢ after the name of the gemstone, that means that gemstone can be lab-created. Lab-created stone has same chemical formula as the natural gemstones.

Cleaning: USC means ultrasonic cleaner.
Please note, that the gemstone may fall of from the jewelry if it is not setted right. Ultrasonic cleaners aren’t suggested to use at home because of this.
⊕ – Ultrasonic cleaner can be used carefully; Inspect the stone, that it doesn’t have any cracks or the stone hasn’t treated other ways.
√ – Can clean in ultrasonic cleaner
× – Do not use ultrasonic cleaner
Cleaning has four different categories.
| Soap | Water | Soft brush | Soft cloth |
 |  |  |  |
| Mild (unscented) soap. For example, a dishwashing liquid. One or two drops is enough. | Hand-warmth water or a little bit colder. | Soft brush – unused toothbrush or small brush for painting. | Frizz-free, soft and clean cloth. |
Remember to check up the stone before you start to clean them! If the stone has scratches or cracks, ask from the jeweler can you clean the jewelry/gemstone. You can drop stone/jewelry in warm water (with soap, if the stone can handle it) and leave it lay there for a while, so the filth softens and loosens. After this, you can carefully brush the filth away / use the soft cloth. After cleaning, use dry cloth to dry off the jewelry / gemstone.
It is good to have frizz-free cloth just for cleaning and drying the stones, so the cloth doesn’t scratch the jewelry and stones.
If you have unfamiliar gemstone to you, a jeweler can identify the stones for you.
