In short
Diamond shape symbolism: round (timeless commitment), princess (modern authority), oval (continual love), pear (tears of joy), marquise (royalty), emerald (clarity and tradition), cushion (vintage romance), heart (open love), radiant (bold confidence), and asscher (architectural depth). Round leads US sales at ~55%; lab-grown 1.50ct G/VS1 builds run $2,000-$3,500 in 14k white gold.
