Gaurav thus confirmed another medal to the Indian tally as every boxer in the last-four stage is assured of a spot on the podium.
Up against the vastly more experienced Keama in Wednesday's quarter-final, Gaurav delivered a composed, technically superior performance.
Gaurav landed more scoring punches in a frenetic opening period, thus taking the early advantage.
The second round followed a similar script with Gaurav penetrating Keama's defence with powerful jabs on several occassions.
Keama came out swinging in the third and last period in an effort to reduce the gap, but Gaurav did well to retaliate in an effective manner and take a well-deserved victory.
