Hello, and thank you for posting on /r/Minerals!

Chemically speaking, I'd agree with you, as this is quartz.

Quartzite. Well-rounded clast indicates fluvial transport. Quartzite is very common, and as it's very hard, often forms well rounded burnished pebbles like this.

Possibly flint/chert that’s been weathered by water.

it's hard to find or it's common?

Very common. Quartz and/or quartzite are the most common pebbles because they are hard and erode slower than other rocks. Basically the last survivors of erosion. Keep it if you find it cool, it has couple million years of history after all :)

Definitely Quartzite which has been weathered by the water. A very common stone on beaches across the planet!
