Graphite from Ceylon (Sri Lanka).
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5900 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
Elements are fundamental substances of matter - matter that is composed of the same types of atoms. At present, 118 elements are known (four of them are still unnamed). Of these, 98 occur naturally on Earth (hydrogen to californium). Most of these occur in rocks & minerals, although some occur in very small, trace amounts. Only some elements occur in their native elemental state as minerals.
To find a native element in nature, it must be relatively non-reactive and there must be some concentration process. Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state.
The element carbon principally occurs in its native state as the minerals graphite (C) and diamond (C). Graphite is the common & far less valuable polymorph of carbon. Graphite has a metallic luster and a silvery-gray color. It is very soft (H = 1), has a slick, greasy feel, and readily marks paper. Graphite does have cleavage, but it is not apparent at the hand specimen scale. The ability of graphite to mark paper, its softness, and its greasy feel are all a consequence of cleavage sheets easily slipping over each other on a microscopic scale.

Graphite Drawing on Bristol Vellum
Dimensions: 8 1/2" x11"
The idea behind this drawing was the duality of Love & Death - in Greek myth, they were brothers - Eros and Thatanos. I felt it was a metaphor of love - instead of Cupid's arrow, a shotgun blast. Which, unfortunately, can also imply violence, and Crimes of Passion.

While many families and societies endorsed the provision of education among their children, regardless of gender, many young women have been deprived of this opportunity. Additionally, any of those who stood in the way of the oppressors to fight for the basic right to learn have been demolished physically and emotionally. This sketch depicts a story in which these oppressed individuals are in fear as they are heading to school, afraid of what these oppressors might do to them at any instant. Their bike ride to school could simply be their last.This is why the bike is composed of a collaboration of tormented expressions and human organs to emphasize the prevalence of graphic gore, discomfort, irritation,and trepidation in such atmospheres.While Malala Yousafzai attempted to fight for these rights, she was encountered by these extremist antagonists in the most repugnant ways possible. This illustration is depicted in the honor of her diligent attempts and those who were deprived .
