  abstract = {{H}ollow channels in diamond are well acknowledged to be the result of dissolution processes. {I}n this article we demonstrate that some hollow channels in natural diamonds are the consequence of intense plastic deformation by mechanical twinning. {T}wo mixed-habit diamonds presenting numerous geometrical hollow tubes were studied. {X}-ray {L}aue analyses showed the presence of microtwins. {A}t the intersection of microtwins, displacements and cracks are generated, creating the hollow channels observed. {T}he presence of the cracks seems to have released the internal stress, as there was less to no signs of deformation at and around them. {F}urther dissolutions are sometimes but not always seen within the cavities. {M}echanical twinning, so far mostly identified in pink to purple diamonds, might be more widespread than originally thought in natural diamonds.},
