Modern Birthstones vs. Traditional Birthstones

Birthstones have evolved over time, shaped by cultural traditions and gemstone history. Early societies linked specific gems to months or astrological signs, believing each carried unique meaning, a custom that eventually became today’s tradition of wearing a gemstone tied to one’s birth month. 


Some months have both a modern and a traditional birthstone. Traditional birthstones reflect historical symbolism, while modern birthstones were introduced to align with contemporary styles and gemstone availability.

 

  • Traditional Birthstones: Garnet (Jan), Amethyst (Feb), Bloodstone (Mar), Diamond (Apr), Emerald (May), Pearl (Jun), Moonstone (Jun), Ruby (Jul), Sardonyx (Aug), Sapphire (Sept), Opal (Oct), Topaz (Nov), Turquoise (Dec), and Lapis Lazuli (Dec). 
  • Modern Birthstones: Garnet (Jan), Amethyst (Feb), Aquamarine (Mar), Diamond (Apr), Emerald (May), Pearl (Jun), Alexandrite (Jun), Ruby (Jul), Peridot (Aug), Spinel (Aug), Sardonyx (Aug), Sapphire (Sept), Opal (Oct), Tourmaline (Oct), Citrine (Nov), Topaz (Nov), Tanzanite (Dec), Zircon (Dec), Turquoise (Dec), and Blue Topaz (Dec). 


Choosing between modern and traditional birthstones is a personal decision. Some are drawn to the history behind traditional gems, while others prefer the brilliance and accessibility of modern stones. Both traditions highlight the timeless connection between gemstones and self-expression.
