Does a diamond have all equal sides?

Diamonds are unique shapes because they have many different geometric attributes. A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal.

Can a diamond be a rectangle?

The Criss cut is a relatively new diamond shape. Like the Emerald cut, the Criss Cut is elongated in shape with trimmed corners but unique in that the step-like facets cross each other in a criss-cross fashion. Polished with 77 facets, the Criss Cut diamond can either be rectangular or octagonal in shape.

What angles make a diamond?

The diamond cubic crystal structure is based on the body-centered tetragonal Bravais lattice (remember that face-centered tetragonal is the same as body-centered tetragonal). There are 4 atoms per unit cell, and each atom is tetrahedrally coordinated so that it has 4 nearest neighbors.
