genuinerudraksha

Hi, I am new to this club. I want to test the authenticity of the rudraksha by copper coin test/ boiling in the water/ to take it to expert and get examined them by magnifying glass etc.. Can some body tell me one can test the rudraksha authenticity after energizaing them. (delivered from the vendor. They send rudrakhas after energizing them). Do the tests effect the power of rudrakha ( Can I keep them in my pooja place after testing them). Do I need to re energize them. Is there any harm of conducting the tests after energizing them. Please help me Thanks in Advance
