Lozenge

A lozenge (◊), often referred to as a diamond, is a form of rhombus. The definition of lozenge is not strictly fixed, and it is sometimes used simply as a synonym (from the French losange) for rhombus. Most often, though, lozenge refers to a thin rhombus—a rhombus with acute angles of less than 45°. The lozenge shape is often used in parquetry and as decoration on ceramics, silverware and textiles. It also features in heraldry and playing cards.

Symbolism

The lozenge motif dates as far back as the Neolithic and Paleolithic period in Eastern Europe and represents a sown field and female fertility. The ancient lozenge pattern often shows up in Diamond vault architecture, in traditional dress patterns of Slavic peoples, and in traditional Ukrainian embroidery. The lozenge pattern also appears extensively in Celtic art, art from the Ottoman Empire, and ancient Phrygian art.

The lozenge symbolism is one of the main female symbols in Berber carpets. Common Berber jewelry from the Aurès Mountains or Kabylie in Algeria also uses this pattern as a female fertility sign.

Lozenge (heraldry)

The lozenge in heraldry is a diamond-shaped charge (an object that can be placed on the field of the shield), usually somewhat narrower than it is tall. It is to be distinguished in modern heraldry from the fusil, which is like the lozenge but narrower, though the distinction has not always been as fine and is not always observed even today. A mascle is a voided lozenge—that is, a lozenge with a lozenge-shaped hole in the middle—and the rarer rustre is a lozenge containing a circular hole in the centre. A field covered in a pattern of lozenges is described as lozengy; similar fields of mascles are masculy, and fusils, fusily (see Variation of the field).

In civic heraldry, a lozenge sable is often used in coal-mining communities to represent a lump of coal.

Lozengy

The blason Lozengy is a form of variation of the field or of another charge (for example a chevron lozengy) which consists of lozenges semée, or sown like seeds (Latin: semen, a seed), or strewn across the field, but in an organised contiguous pattern.
