Dreamer Designs carries 2 diamond shapes, square or round. Our premium 2.5mm resin square diamonds with 13 or 9 surface cuts reflect light for an ultra shiny effect. Square diamonds are the perfect option for those who want the fullest representation of their artwork. Although placing them down requires more precision, square’s benefit from fitting edge-to-edge. With no canvas showing through, they help provide a complete mosaic effect. Our premium 2.8mm resin round diamonds with 26 surface cuts (double compared to competitors) shimmer like no other! Round diamonds are generally preferred by beginners, as they are easier and faster to pick up and place on the canvas.
