Ruby vs garnet

Ruby's red comes from chromium; garnet's color depends on the variety, with almandine and pyrope ranging from deep wine to rosy red.
Garnet
Garnet reads warmer with more burgundy undertones at a fraction of ruby's cost. Ruby is the harder, brighter, and more saturated stone, with significantly higher price points and cultural weight as the July birthstone and a symbol of passionate commitment.
