金絲楠木是軟木之王，金絲楠木是很多楠木中的一種，最名貴的一種；反過來講，很多楠木，確實是楠木，但不是金絲楠木。只有甄南木樹上下來的木頭，而且要經過百年以上的放置或者是使用之後，才是過去真正意義的金絲楠木。金絲楠木來由：一般是楨楠被伐之後或在水中、或在泥土中、或在空氣中經過成百年的氧化（醇化）之後才形成（一般占楨楠的2%——5%）。2、鑒別標準一般以是否在光照下有金絲為標準。但是依據昔日皇宮內務府的標準有三個：其一年齡在500年以上；其二金絲含量在80%以上；其三直徑在75cm .3、常用鑒別方法：3.1在光照下（最好用聚光手電筒）看到綿綿的金絲：金絲的走向和紋理一致：金絲細如毫髮；隨著角度的不同其色彩、圖案會有不同的。3.2聞香：金絲楠木的香是淡淡幽香，它不像樟木那麼竄，楠木的香味很容易讓人接受，市場介於若有若無之間，讓人覺得靜雅而清透。它不像沉香那麼鬱，沉香有時會給人以膩的感覺，而楠木它是通透的。3.3掂：金絲楠木的氣幹密度為0.61g/cm,較輕。3.4摸：金絲楠木拇指細膩如脂、光滑如緞；冬暖夏涼。圖中紫金絲楠木一整套14件龍紋的裝飾雕工精湛，上等木材成型而制，保存完好 ，古樸雅潤，值得大力收藏。
