This very intricate piece of precision  work  would have taken many days or weeks to crochet by hand.  It is unique in that it is impossible to make  something like this by machine.  It is so well made and crocheted with a very fine hook, that it is very difficult to put a price on it.   I myself have crocheted many fine pieces and I know from experience the work involved.  I am selling this piece because it is one I did not crochet, and I do not think I could have achieved such precision.
