The "Mining Diamond video" Shows that the LENR agent is moving inside the diamond. It is totally encased by the diamond and the agent destroys the diamond(makes it disappear) as it moves inside the diamond. At the end of its movement, it deposits a ball of transmuted material which is also totally encased inside the diamond. This behavior is common to many hundreds of LENR agent trails throughout the volume of the diamond.
From the tone of your criticisms, you did not look at the referenced experiment in the video.
