新石器時代紅山文化（約公元前3500年） 玉馬蹄形器

of circular tapered form hollowed in the centre, the smoothly patinated stone of a variegated grey and light brown colour with darker undertones

There is some surface wear and overall weathering, consistent with age and type. There are a few minute nibblings or nicks around the rims, some with tiny infills (showing under UV), as well as small minute crackles that have been secured with wax but there does not appear to be any major break. The patina and colour of the jade are particularly attractive.
