This gemstone has the full complement of facet steps, four on the pavilion and three on the crown, that I cut on emerald cuts. This makes a deeper more scintillating gemstone that can draw you into its rich colorful world, just like this stone does. Its orange is only slightly burnt and the brown shade does not make the stone darker than desirable. The c axis is very similar to the a/b axis and has the same medium tone level for a lively gemstone. It appears to be eye clean and with fine crystal. To your get surprise, I love this 4.50 carats gemstone and would call it a GEM (exceptional gemstone) except that the brown overtone indicates a less than excellent level of saturation.
