Zircon and Diamond Ring Size 7
The name zircon derives from either the Persian for "gold colored" (zargun), or the Arabic for "vermillion" (zarqun). Zircon is known since the Middle Ages. Due to its high refractive index and strong dispersion, zircon has great brilliance and intensive fire. The luster is vitreous to a brilliant sheen. Zircon is the birthstone for the month of December.
