The square 35 mm donut is the modern take on the classic round donut. Its straight lines and softly rounded corners give the pendant a clean, contemporary character, while the hole in the middle preserves the ancient symbolism of the circle: wholeness, unity and the cycle of life. At 35 mm this is the largest square size in our collection. The wide surface beautifully shows off the natural pattern of the stone, from the lace-like bands of Crazy Lace Agate and the white flakes of Snowflake Obsidian to the deep blue of Sodalite 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.
