gems, corundum, sapphire, Burma.12

Gems are renowned for their outward beauty, but their in-ternal world can be just as striking. Lotus Gemology re-cently came across a Burmese sapphire, cut as a cabochon and measuring 8.92 × 7.10 × 4.75 mm, that displayed a six-rayed star. Once we examined it under the microscope, we were surprised to find that this celestial theme carried through to the inclusion scene inside (figure 13).
