This is the largest stack of mica chips I have ever seen. The pieces of mica are 7.5" by 6.5" and the stack is 1.25" thick. The mica alone weighs 1.44 lbs. The measurements are for the most of the pieces, some as you know mica, have split and fallen off. It is such a fragile beautiful piece. It will definitely be a conversational piece wherever you place it.
