Welcome to Tnet
As ‘Squirrel322’ says, the imagery originates in Japan but they’ve also been made in China. As ‘alan m’ says, I’m sure it will be glass, although the term ‘crystal’ is also used for some types of glass.
You’ll find them with the monkeys carved from wood, ivory or its substitutes; or cast from bronze or other metals; and with the ball in a variety of colours. The problem here is that it could be moderately valuable but that will depend on the quality to which it has been made, how old it is, and whether it has any signature of other markings to attribute it as not modern.
To give you an idea, the first one below has a bronze cast stand which is signed and can be attributed to the 19th Century from Japan. It sold for $1,880. The second one is a modern feng-shui item and would sell for less than $40.
I know the modern one is gaudy and obviously not an antique but I’m showing you the two extremes… and everything in between those extremes exists too, including pieces which cannot be reliably dated, except to say they’re probably vintage but not antique. My guess is that yours is vintage and perhaps has a low three-figure value… unless it is authentically marked or signed.
Looking closely at your pictures, if yours is cast metal then the casting is not of high quality. The ball also appears not to be a perfect sphere. It looks to have a flattened area where the monkeys are supporting it.
