An ALR stamp on a diamond indicates that it has undergone an Advanced Light Refraction (ALR) process, which enhances its optical properties, such as brilliance and fire. This treatment is aimed at improving the diamond's appearance, making it more visually appealing. However, it's essential for consumers to understand that treated diamonds may differ in value and durability compared to untreated stones. Always verify the credibility of the certification and the treatment process before purchasing.
