Jennifer Harding has a really nice colorful book that displays the chakras by rays of color. It’s always a nice go-to book if you need a quick reference.
In general it’s also really easy to just google crystal info healingcrystalsforyou is a good one or shimmerlings.com Or simply type something like “ kyanite metaphysical properties” and you’ll get what you need.
A lot of people like the crystal bible too but i always felt that one was a little dry in comparison to some others. Not sure where you are on your path but if you’re a beginner i suggest the Book of Stones would be perfect for you.
This is funny because i was literally just looking at my crystal book maybe a few hours ago!
