No. It's man-made.
No. By definition a mineral is naturally occurring.
No, it is a naturally occurring petrochemical.

Not all the elements occur naturally; some elements are man-made.

A dress is manmade. It is created by humans using a variety of materials such as fabric, thread, and embellishments. It is not naturally occurring in nature.
Pumice is a naturally occurring volcanic rock.
Zircon itself is a naturally occurring mineral, so it is not manmade. However, some zircon gemstones undergo treatments, such as heat treatment, to enhance their color or clarity, but the base mineral itself is natural.
ADNR's are a special manmade form of pure carbon that are harder (and denser) than natural diamonds and manmade ultrahard fullerine. I believe the answer is lonsdaleite. It is naturally made and is 58% harder than diamonds.
It is the hardest NATURAL substance- due to the arrangement of the carbon atoms that make up a diamond. (Thee ARE harder materials, but they are manmade.)
In the attached list manmade elements are: technetium, promethium and the elements with atomic number between 94 and 118.
Hydrogen is the most abundant element in the universe and is naturally occurring. However, most of the hydrogen used by humans is produced through industrial processes such as steam methane reforming or electrolysis of water.
