These Guatemala Jade beads are perfectly round, the holes perfectly centered, the high polish absolutely impeccable. These beads are opaque, monochromatic and have the unmistakable “feel” of fine jadeite. Colour rendition is notoriously difficult for blue-greens hues and colours, and the beads I received were, in person, more gray-green than bluish green. Still an outstanding purchase and, truly amazing in person.
