The Asscher cut is the diamond shape that draws you in and does not let go. Developed in 1902 by the Royal Asscher Diamond Company in Amsterdam, it is one of the most storied cuts in the history of fine jewellery. Its square shape, deeply cut stepped facets, and high crown create a captivating hall of mirrors effect inside the stone - concentric squares of light that appear to go on forever. It is architectural, it is art deco, and it is unlike anything else in the diamond world. At Real Canarys, our Asscher cut lab grown diamond engagement rings are crafted for those who are drawn to vintage character, geometric precision, and quiet luxury. The Asscher cut rewards a simple, understated setting - a sleek solitaire that lets the stone's inner world take centre stage, a slim pavé band that adds the gentlest touch of brilliance without competing with the cut, or a sophisticated bezel setting that frames the square shape with clean, modern lines. Whatever setting you choose, the Asscher cut brings a depth and complexity to the ring that no brilliant cut can replicate. Every ring in this collection is IGI certified, available in yellow gold, white gold, rose gold and platinum, and made to order exclusively for you. Conflict free, ethically sourced, and shipped free anywhere in the world. The Asscher cut is for those who see jewellery not just as an accessory but as a work of art.
