The bypass ring treats negative space as material. Its open silhouette contributes to perceived size and structural complexity as directly as the metal does.
Stone Story
Fancy color sapphires cover virtually every color in fine jewelry. Presenting in pink, yellow, orange, green, purple, and teal, each one is produced by a different trace element within corundum. They all share the same 9 Mohs hardness as blue sapphire, which means you're not trading durability for color.
