Moved to a more appropriate category.
This is NOT a forum announcement.

My guess is, it is not a natural stone but a laser optic that displays a cats eye effect. Chatoyancy.

My guess is, it is not a natural stone, so I do not believe it is chalcedony, but a laser optic glass like your other post with the pink stone.

If I had to guess, I'd go with fiber optic glass too.

More of the same.....fiber optic glass.

There is also a glass imitation of chatoyant gems made from a colored fiber optic to provoke a similar visual effect. These glasses come in a variety of different colors and are easily distinguishable from natural gems by observation from the side view of the cabochons, in direction parallel to glass fibers.
