If your piece is made up of only one solid piece of only one substance, element, or mineral. then yes because there is no other substance that makes it impure.If you take a common element like gold and form it into a bracelet than you have a pure piece of jewelry because it does not contain olivine or magnetite or any other mineral, rock or element.
As a naturally occurring metallic mineral it is rare. As an element or component in the chemical composition of rocks and minerals, extremely common.
