Zircon
Zircon is somewhat soft, so avoid scratches and sharp blows. Avoid hot water and household chemicals. Brown zircon is usually heat treated to change it to colorless or blue zircon. Blue stones that revert to brown will regain the blue if reheated. Blue zircon reheated in the presence of oxygen will change to a golden yellow. Zircon experiences more wear on its facets than diamond. Zircon is imitated by colorless glass and synthetic spinel.
