We have searched for strangelets in a triggered sample of 61 million central (top 4%) Au+Au collisions at √s_NN=200 GeV near beam rapidities at the STAR solenoidal tracker detector at the BNL Relativistic Heavy Ion Collider. We have sensitivity to metastable strangelets with lifetimes of order \ensuremath\geqslant0.1 ns, in contrast to limits over ten times longer in BNL Alternating Gradient Synchrotron (AGS) studies and longer still at the CERN Super Proton Synchrotron (SPS). Upper limits of a few 10^\ensuremath-6 to 10^\ensuremath-7 per central Au+Au collision are set for strangelets with mass \ensuremath\gtrsim30 GeV/c2.
