Common opal typically exhibits a light opal color naturally, but when treated through heating or additives, the sandstone darkens, thereby enhancing its reflective properties. Fairy stone may sometimes be mistaken for Andamooka treated matrix, which can resemble a cement-like structure rather than a sandstone base. While sugar and baking solutions were historically used for treatment, modern techniques now favor advanced resin stabilization processes for enhancing the stone's characteristics.
