About Ruby
Ruby is red corundum, the same mineral as sapphire, colored by chromium. July birthstone rubies range from pinkish red to deep blood red.
Ruby has symbolized passion and protection for centuries, and fine rubies have rivaled diamonds in value.
Color and Quality
The best rubies show vivid, even red without brown or purple dominance, and look red in both daylight and indoor light.
Pigeon blood red is a trade term for vivid red rubies, but color should be judged face-up in natural light, not by trade terms alone.
Durability and Wear
Ruby rates 9 on the Mohs scale, hard enough for daily rings in protective settings, and well suited to pendants and earrings.
Most rubies are heat treated to improve color, which should be disclosed. Untreated fine rubies are rarer and cost far more.
Choosing and Gifting
Choose ruby by face-up red color first, then by clarity that does not cloud the stone, and ask about treatment disclosure.
Ruby suits July birthdays and fortieth anniversaries traditionally, and pairs well with yellow gold and platinum.
