Macle is a term used in crystallography. It is a crystalline form, twin-crystal or double crystal (such as chiastolite). Macle is an old French word, a heraldic term for a voided lozenge (one diamond shape within another). Etymologically the word is derived from the Latin macula meaning spot, mesh, or hole.
