Properties: Diamond (faceted): Because of its perfect symmetry, the diamond vibrates toward harmony. A diamond is really two triangles, end to end. It is also a cross with the outlines drawn together. This makes it an excellent shape for meditation gardens or those used for culinary purposes. As this shape also vibrates toward the solidity of Earth, it’s a good bet for magical gardens involving prosperity and abundance, and issues of the family, home, and hearth.
Diamond is the hardest known natural material on both the Vickers and the Mohs scale. Diamond’s hardness has been known since antiquity, and is the source of its name.
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.
The lozenge or rhombus dates as far back as the Neolithic and Paleolithic period in Eastern Europe and represents a sown field and female fertility. The ancient rhombus pattern often shows up in Diamond vault architecture, in traditional dress patterns of Slavic peoples, and in traditional Ukrainian embroidery. The rhombus pattern also appears extensively in Celtic art, art from the Ottoman Empire, and ancient Phrygian art.
The lozenge (rhombus) 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.
In 1658, the English philosopher Sir Thomas Browne published The Garden of Cyrus subtitled The Quincunciall Lozenge, or Network Plantations of the Ancients where he outlined the mystical interconnection of art, nature and the Universe via the quincunx pattern. He suggested that ancient plantations were laid out in a lozenge pattern.
Lozenges (rhombus) appear as symbols in ancient classic element systems, in amulets, and in religious symbolism. In a suit of playing cards, diamonds is in the shape of a lozenge.
