Hi Tim, You might try a carbide drill intended for drilling glass. These are spade shaped pieces of carbide brazed onto a steel drill shank. They're available in hardware stores here, probably there as well. Failing the drilling, could you get some gold or silver wire from a jewellery supply house and enclose the rock in a sort of harness with a loop at the top?
