July, a month of warmth and vibrant energy, is crowned with a birthstone that embodies passion and power—ruby. This striking red gem has captivated civilizations for millennia, symbolizing love, courage, and vitality.
Ruby is the July birthstone — corundum colored by chromium at Mohs 9 hardness, second only to diamond. Top untreated Burmese pigeon's-blood 1.00ct+ stones run $5,000-$15,000 per carat at New York retail; Mozambique and Thai stones $200-$3,000 per carat. Ruby also marks the 40th wedding anniversary. Insist on a GIA, AGL, or SSEF report for high-value purchases.
In this comprehensive guide, we'll explore ruby's rich history, remarkable properties, and enduring symbolism as the jewel of July.
