Bumrah has been the star performer for India in the ongoing Border-Gavaskar Trophy.
Bumrah also proved his worth in the rain-marred third Test at the Gabba, picking up nine wickets in the match, which ended in a draw.
Speaking on Cricbuzz, former India wicketkeeper Dinesh Karthik heaped praise on Bumrah, calling him a "freak of nature" and comparing him to a priceless "Kohinoor diamond" that must be protected.
"He is a freak of nature. I used this term before, and I am not shy of using it again. He is that 'kohinoor' diamond that we need to protect every day. What he does out there is special. There is no bowler that can do what he is doing in the world today across formats," Karthik said.
After his stunning exploits in Brisbane, Bumrah became the most successful Indian bowler in Australia, with 53 wickets in 10 Tests at an average of 17.15, going past Kapil Dev's tally of 51 scalps in 11 matches.
Karthik also lauded Bumrah's calm demeanor and strong resolve, stating that it reflects on his batting as well.
"His staunch ability and resolve come through his batting as well. I've seen him bat, obviously, it's something he is always working on so he can contribute. For me, it's his character. You speak to him - very simple, very calm, very self-confident. And his aggression comes through the way he bowls, not through what he says," Karthik remarked.
Having made his Test debut in 2018, Jasprit Bumrah has claimed 194 wickets in 43 matches at a remarkable average of 19.53, including 12 five-wicket hauls.
Karthik hailed Bumrah as "one of the greatest fast bowlers India has produced without a shadow of doubt" and described him as an "absolute legend in every sense already with the ball."
With the BGT currently tied at 1-1, all eyes will be on Bumrah whether the Indian pace spearhead produces brilliance again to script India’s another historic Test series win Down Under.
