Zircon jewelry should be stored carefully because although zircon is relatively hard, it can abrade and facets can chip. Dealers often wrap zircons in individual twists of paper so that they will not knock against each other in a parcel.

Zircon is a natural stone - not to be confused with Cubic Zirconia which is manmade. It is known as a colorless stone used to imitate diamonds but also comes in: blue, yellow, orange, red, brown and green . It has a hardness of 7.5.

Zircon is somewhat soft so avoid scratches and sharp blows. Avoid hot water and household chemicals.

Brown Zicon is usually heat treated to change them 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 will have more wear on its facets than diamond. Zircon is imitated by colorless glass and synthetic spinel.
