The square 28 mm donut combines the modern, clean shape with a compact size. Its straight lines and softly rounded corners give the pendant a contemporary character, and the hole in the middle preserves the ancient symbolism of the circle: wholeness, unity and the cycle of life. Thanks to its smaller size, this donut sits light and unobtrusive on the chest, which makes it comfortable to wear under your clothing too. Yet the surface is large enough to clearly show the color and pattern of the stone, from the deep blue of Sodalite and the warm yellow of Yellow Calcite to the metallic gray of Hematite and the soft pink of Rose Quartz. Green Aventurine, Howlite, Jade, Onyx, Red Jasper and Unakite are also available here in this shape. A square donut is worn on a leather string or waxed cord through the hole, or with a donut holder on a chain, flat on the chest and close to the heart.
