Made a stone, like a canna, with bright spots like gold powder, smooth as a mirror, please tell me.

Generally, it is gold sand with the same bright spot as gold powder, but this color is different. Very smooth. Keep it if you like. Just have fun.

Jinsha stone, also known as Jinxingshi, is one of the golden stones. Also known as "placer ore", it is an opaque ore body that shines under strong light, like mica flakes in gold foil, shining like Venus, hence the name.
