I bought a Hampton Bay MirMar 60 inch ceiling fan from home depot. One of the globes was accidentally broke during installation, where can I get these globes?

That is not omething you can get anywhere. This a made for HD by Fan King. I can't take any credit for this contact info, ceilingfanrepair did it better than I could. https://www.askmehelpdesk.com/electrical-lighting/ceiling-fan-troubleshooting-repair-frequently-asked-questions-46738.html#post220359

B is correct, you have to order the globe from the manufacturer. Note the link he posted.
