Every KOBK object is one of one and carries its age honestly. Expect marks, wear and patina as part of the piece; any specific fault is noted above. Where an object is photographed on a stand, the stand is included.
Notes
Classification can wait. The object already holds. A dark blue-green core passes out through a paler outer skin, giving the slab the feel of something opened rather than made.
"Jade" covers two different minerals, jadeite and nephrite, prized across cultures for hardness and colour long before anyone could tell them apart by chemistry. Which one this is has not been tested, so we are not claiming it. If testing later resolves the variety, we will add it. For now the strength is physical: weight, colour, and the clean break between rough edge and polished face.
