到底要怎麼看待古代玉器的鑑賞與收藏呢？這句話以今日比較宏觀的角度與考量下，至少應該具備以下四層意義。最世俗第一層意義是：怎麼鑑定古玉的好壞與價值；第二層意義是：怎麼鑑定一件玉器的真實製作年代，與其所應有的形制、器名與社會文化上的價值；第三層意義是：人文的與藝術上的評價；最後還是要站在文化資產保存維護的最終目的上頭去（藝術無價？還是無價藝術？）。前者所涉及的，主要是礦物學或實質材料上的問題，但它只能解決是玉是石的質材認定問題，而非鑑定的全部。而次兩者所涉及的，則偏重在人文藝術上的文物鑑賞與時代審美品味方向，最後才是站在文化資產保存與維護的觀點與使命上去分享經驗，本文乃就以上這四層意義去談鑑賞與保存維護的問題。

How should we evaluate the appreciation and collection of ancient jade? From the broad perspectives of today, there are at least the following four dimensions. First how are the quality and value of jade established. Secondly, how do we identify the production date, shape, name, and social and cultural value of jades. Thirdly, from the perspective of humanistic and artistic evaluation. Ultimately, however, it is necessary to focus on cultural asset preservation （Is art priceless or not?）. The former involves mainly problems of mineralogy or substantive material, but it can only solve the material identification problem of whether an item is a jade or a stone; it is only part of the issue of identification. Both concern the cultural art of cultural appreciation and the aesthetic taste of the times, ultimately depending on points of view and missions of cultural assets preservation and maintenance to share the experience. This article aims to discuss the problems of appreciation and preservation from the perspective of the above four dimensions.
