The Asscher Brothers were a prominent family of diamond cutters and jewelers from the Netherlands, known for their innovative techniques in diamond cutting. Founded in the late 19th century, they gained fame for creating the Asscher cut, a square-shaped diamond cut that enhances the stone's brilliance and clarity. Their craftsmanship set a high standard in the diamond industry. In 1902, the Asscher Brothers were commissioned to cut the famous Cullinan diamond, the largest gem-quality diamond ever found. Their work on this diamond solidified their reputation and contributed to the popularity of their unique cutting style. Today, the Asscher cut remains a sought-after choice for engagement rings and fine jewelry.
