  abstract = {{T}wo polished slices of flower-shaped trapiche ruby from {M}ong {H}su were analysed by {X}-ray computed tomography and {X}-ray micro-fluorescence. {T}hey are characterised by the presence of a core overgrown by two layers of ruby (with the outer one forming the 'petal' shape), and these three domains were previously attributed by {L}iu (2015) to a multi-stage growth mechanism. {T}he present research indicates that these specimens show textural sector zoning associated with chemical sector zoning. {I}n agreement with literature data, three different growth sectors are identified: a pinacoidal growth sector (corresponding to the core) and two sets of dipyramidal growth sectors with different inclinations with respect to the c-axis. {T}he core, middle and outer layers are thus growth sectors of the same crystal, and no successive stages are needed to explain their formation. {T}herefore, the growth model proposed for other trapiche rubies from {M}yanmar also applies to the formation of these flower-shaped specimens. {T}he distinctive shape of these rubies is due to weathering of the growth sectors and the sector boundaries.},
