If you're looking for the Hindi word for a specific type of stone, you need to provide more context. For example:
* If you're talking about a black stone used in religious ceremonies, the Hindi word would be "kaala patthar" (काला पत्थर).
* If you're talking about a hard stone used for grinding, the Hindi word would be "chakki ka patthar" (चक्की का पत्थर).
Please provide more details so I can help you find the appropriate Hindi translation for "karakkaya".
