440Hz or 432Hz?

Yes all bowls are available in 432 Hz if this is what you are drawn to!

It has been claimed that the 432Hz frequencies heightens perception, reduces anxiety, blood pressure and unlocks intuition. You will need to look more into this and decide on what you believe and what's more important to you.

If you want 432 Hz your bowls just remember that they won't be in tune with "normal" 440Hz tuned instruments such as piano or native American flute, or a hand pan/ tongue drum that is 440Hz.  So, it's important to decide from the beginning if you will be collecting all instruments for your set that are 432Hz or 440Hz so they harmonise well.
