What is My Birthstone?
Throughout history, people have given poetic meanings to different gemstones. Nowadays, our use of birthstones is probably the best-known example of this practice. Each month has a special stone assigned to it. For those born in a particular month, that month’s gem purportedly acts as a “good luck” charm. Of course, birthstones and their meanings vary across cultures. Below you’ll find a list of birthstones commonly used in English speaking countries.
MONTH |
MODERN |
ANCIENT |
---|---|---|
January | Garnet | Garnet |
February | Amethyst | Amethyst |
March | Aquamarine | Bloodstone |
April | Diamond | Diamond |
May | Emerald | Emerald |
June | Alexandrite | Pearl |
July | Ruby | Ruby |
August | Peridot | Sardonyx |
September | Sapphire | Sapphire |
October | Rose Zircon | Tourmaline or Opal |
November | Golden Topaz or Citrine | Topaz |
December | Blue Zircon or Tanzanite | Turquoise or Lapis |
The “modern” list was created in the early 20th century. However, it never really replaced the “ancient” or traditional list. It became more of a supplement. Today, people freely choose between modern and ancient options. In addition to these, some people consult alternative birthstone lists, including lists based on astrological signs and birth hour.
In Germany and Scandinavian countries, gem enthusiasts prefer moonstone as the June birthstone. “Moonstone” by Gaia Metal Studio. Licensed under CC By-ND 2.0.
