Size: Approximately 12cm x 11.5cm, thickness approximately 2cm. A dark brown non-slip sheet is attached to the back. Details such as the country of origin are unknown, and it has been stored at home for a long time. I believe, but I'm not certain, that it was likely colored a deep blue through a heat treatment process. The contrast between the agate and the quartz is very beautiful. The center is oval-shaped and recessed, so it can be used as a tray to hold accessories such as earrings or rings. There are a few small scratches, and when the recess in the center was carved, the quartz part seems to have chipped slightly in a jagged way. There are also scratches next to it. Photo 3 is the easiest to understand. It is not suitable for those who are concerned about minor details. However, please do not hesitate to ask any questions you may have about any areas of concern. It will take a little time, but I can also add photos.
