Excuse me, where is the appraisal agency for stone quality?
1. If there is any problem with the decoration stone, you'd better find an appraisal agency recognized by the court!
2, and if you want to identify hardness and minerals, go to the quality supervision and inspection station of rock and jade products.
To put it simply, you can go directly to the Geological Bureau to find ore identification, but these costs are very expensive.
If you have friends who go to college, you can go to the university laboratory for examination.
If the above answers are useful to you, please praise me and send me up to help more people. Thank you, hope to adopt!
If you don't understand anything, you can ask it, and then reply or send a private message when you see it!
