Bold Dimensional Form with Magical Aurora Brilliance – Preciosa 2989 3/4 Ball MAXIMA Crystal AB

The Preciosa 2989 3/4 Ball MAXIMA Flatback is designed to stand out—literally. Its unique high-domed shape replicates three-quarters of a polished crystal sphere, creating a rounded, elevated surface that catches and bends light in all directions. The abundance of facet angles around the dome produces a vivid play of reflections, making this shape ideal for adding tactile texture and heightened sparkle to any piece.

In Crystal AB, this elevated brilliance is enhanced by the famous Aurora Borealis effect—a thin, transparent coating applied over the clear crystal base. This coating refracts light into a soft rainbow spectrum, with pink, violet, aqua, green, and golden glints appearing as the piece moves. The AB effect adds depth and dreamlike beauty to the shape while highlighting the 3D domed contour of the crystal.
