PPT-Zircon By: Ericka Boudreau

Zircon By Ericka Boudreau Physical Characteristics Zircon Structure Isolated SiO 4 tetrahedra share corners and edges with ZrO 8 dodecahedra Repulsion between Zr 4 and Si 4 cations causes distortion creating potential sites for elemental impurities.

It is bitter but true that diamonds are costlier stones but at the same time, they are the dazzling and shining stones that are considered under the category of gemstones.
