Make a crown with three tiers: one half carat round brilliant diamond on top illuminated by six 0.02 carat round brilliant diamonds. Immediately below this is one 0.3 carat princess cut dark aquamarine sideways. On the middle tier at the center is an eight carat amethyst heart surrounded by one carat halo of princess cut diamonds. Centered on the bottom tier is one 0.3 carat princess cut aquamarine sideways. At the bottom one half carat round brilliant cut pink sapphire is illuminated by six 0.02 carat round brilliant blue sapphires.

Design a stunning three-tier geometric crown, emphasizing sharp lines and symmetrical shapes. The top tier features a central 0.5-carat round brilliant diamond, surrounded by six petite 0.02-carat diamonds, forming a precision pattern. Below, an angular 0.3-carat sideways princess cut dark aquamarine enhances the geometric motif. The middle tier showcases a striking eight-carat amethyst heart, elegantly encircled by a halo of princess cut diamonds, each cut precisely creating a dazzling contrast. The bottom tier highlights another 0.3-carat sideways princess cut aquamarine, flanked by a radiant 0.5-carat round brilliant pink sapphire, all lifted by six geometric blue sapphires, delivering refined elegance and modern artistry.
