Vintage Chinese jadeite seal with carved face

Description

Welcome! For auction is this Chinese jadeite seal with four characters carved on the face. Measures appx. 3/8 x 3/8 x 1 7/8". Flaw line inherent to stone going around much of upper midsection. Rough patch/discoloraton/flaw line at top as can be seen in images. No real damage though. I am nut sure of age but a nicely polished piece of jadeite. Please see images for details.
