When choosing a piece of fine jewelry or designing a dream engagement ring, understanding diamond shapes is essential. While many use the terms "shape" and "cut" interchangeably, they refer to two different things. Shape describes the physical outline of the stone when viewed from above, whereas cut refers to how well the facets interact with light.
From timeless classics to modern geometric statements, each diamond shape carries a unique personality, brilliance level, and visual effect.
