ASS #5 - Diamond Crystal Structure and Atomic Theory

A type of diamond crystal shape.Common in some diamond deposits.

The most common shape of gem-quality diamonds, but rarely found perfectly formed.

The partial dissolving of a diamond's outer surface during transport.

Diamond crystals formed from two or more parts growing symmetrically together.

A common type of twinned diamond crystal, often shaped like a flattened triangle.

Solid masses of individual, randomly oriented diamond crystals.

Diamond rough that lacks transparency and uniform shape; often used for industry.

Diamond rough that has a more uniform shape, suitable for jewelry.

A symmetrical mineral specimen, often formed from repeating units of atoms.

A strong bond formed when atoms share electrons.

The basic building block of matter, composed of protons, neutrons, and electrons.

The smallest repeating group of atoms within a crystal, defining its structure.

A strong, interlocking atomic structure of carbon atoms connected in tetrahedral groups, bonded covalently.

A pyramid-shaped group of four atoms, central to diamond's structure.

The characteristic shape of a crystal, reflecting its underlying atomic structure.

The smallest unit containing the characteristic chemical composition and crystal structure of diamond's interlocking tetrahedral groups.

The internal arrangement of repeated patterns of atoms in a crystal.

The relationship between a substance's weight and volume.

Planar surfaces in a mineral that are weak atomic bonds, giving it a tendency to break along these surfaces.

An imperfection or deviation from a perfect crystal lattice in a diamond.

A crystal system where the three axes are perpendicular to each other.

Having the same physical or optical properties in all directions. (in cubic crystals).

Categories of crystals based on their shape and symmetry.

Diamond is denser than graphite due to a tighter arrangement of carbon atoms.

A well-shaped, transparent diamond crystal with eight faces and sharp, square edges.

The repeating pattern of atoms inside a crystal.

Diamond is denser than graphite because its carbon atoms are packed more tightly.

The process where a diamond's outer surface partially dissolves during transport, resulting in smooth, rounded shapes.

Diamonds formed from two or more parts growing together in a symmetrical way, caused by interrupted growth.

Solid masses of individual, randomly oriented diamond crystals, joined together or cemented by a natural binder.

Internal stress within a rough diamond, affecting its strength and cutting difficulty, visible under magnification.

Sorting diamonds into gem-quality (cuttable for jewelry) and industrial-quality (often lacking transparency and uniformity).

Diamond rough lacking transparency and uniformity, used for tools or abrasives, often colored or colorless, may be cube-shaped.

A solid material with a symmetrical structure, formed by repeating units of atoms. Crystals can be organic or inorganic.

Diamond is incredibly hard because its carbon atoms are tightly bonded together in a strong, interlocking structure. This structure is formed by covalent bonds, where atoms share electrons.

The smallest group of atoms that represents the basic structure and chemical composition of a crystal. It is the repeating unit that builds the entire crystal.

It's formed by four tetrahedrons, each with a carbon atom at the center and four surrounding carbon atoms. These tetrahedrons are interconnected by strong covalent bonds.

The shape of a crystal, known as its habit, is determined by the arrangement of atoms within its unit cell.

A strong chemical bond where two atoms share electrons. This sharing creates a strong connection between the atoms.

Diamond's most common habit is the octahedron – a shape with eight equal triangular faces.

Diamond atoms are closer together than any other natural material because of their strong covalent bonds and immense pressure during formation.
