Such external appearances are determined by the internal crystalline arrangement, i.e. the crystalline structure. Fig. 6 shows viewing along c-axis of emerald, and this viewing direction is identical to that of “gota de aceite” effect. Six identical units composed of various element atoms are clearly identified by three crossed auxiliary lines with cyan color. These units are consisted of Si and O as the main framework, consistent with the fact that emerald is a kind of cyclosilicate combined by six Si-O tetrahedrons with one six-fold symmetry axis. Furthermore, as it is known that emerald is colored by Cr and/or V elements, when Cr³⁺ and V³⁺ substitute the Al³⁺ site. Connecting lines between six neighboring Al³⁺ form a hexagonal ring, similar to the outlines of the “spots” as shown in Fig. 7.
