Two generation of calcite crystals. Most of it is yellow translucent. They look square, but when you will see on the edge of the specimen that they are actually elongated. On top there are some white prismatic/thin calcite crystals. The backside of the specimen is cut.

It is from Fujian, and when I asked the Chinese seller about the specific location, he told me it is from Datian County. I have not been able to verify this, but trust the previous owner.

The color will look a bit lighter when adding light, like you see on the video
