2. Is acid-washed aquamarine still considered natural crystal?

3. Is there an aquamarine that is not acid-washed?
There are indeed natural aquamarine that has not been acid-washed on the market. These gems retain the characteristics of natural causes, such as natural flaws and inclusions, and the luster and color are more natural and personalized.

Observe the surface:
Check whether the luster is too perfect, uniform and without natural flaws.
Microscope inspection:

5. Is it harmful to wear acid-washed aquamarine?
Acid-washed aquamarine will not cause direct harm to health under normal wear. However, acid washing may weaken the durability of the gemstone and increase the risk of scratches and breakage. It is recommended to choose natural untreated aquamarine when purchasing to ensure its beauty and durability.
