A signature of Material Good, The Aster  Collection is a study in color drawn from the rarest corners of the sapphire family. Each piece begins with an uncommon stone — green, lavender, seafoam, sage and peach, tourmaline, royal blue — sourced first, then designed around. The result is a collection where no two pieces repeat, each one shaped by the particular character of its center stone. Crafted in the MG Atelier, Aster pairs emerald and cushion cuts with diamond trapezoid accents, letting each sapphire's natural tone carry the design. Bloom by bloom, the collection continues to grow one rare stone at a time.
