The Origin of Birthstones

The idea of a birthstone, a gemstone that corresponds to a person's birth month, is a relatively modern creation. However, its origin dates back to biblical times. Historians believe the twelve gemstones of the breastplate of Aaron corresponded originally to the twelve tribes of Israel. However, Josephus and St. Jerome, in the 1st and 5th centuries CE respectively, began linking these gems with the signs of the zodiac. Presumably, each stone offered wearers special powers during the corresponding astrological period. Therefore, people tried to collect and wear all twelve gems throughout the year as talismans or for therapeutic benefits.

The modern association of one gem to each month, and the practice of wearing just the stone connected to your birth month, arose between the 16th and 18th centuries. The list of so-called ancient or "traditional birthstones" originated in Poland during this time. In the United States in 1912, the National Association of Jewelers released a list of so-called "modern birthstones."

How do Traditional and Modern Birthstone Jewelry Differ?

Although the lists differ somewhat, romantic gem enthusiasts in Western cultures today commonly choose birthstones from both selections. While most contemporary consumers don't typically attribute special powers to these stones, the gems do have popular meanings and associations.

While traditional birthstones include a mix of transparent and opaque gems, such as opal, pearl, and turquoise, the modern list features only transparent gems. Practically speaking, this makes it easier to mix different gems into one piece of modern birthstone jewelry. However, if you prefer the traditional look to the modern alternative, choose one of the ancient stones for your jewelry.


Garnet is January's traditional and modern birthstone. Although garnets are a blend of mineral species with many commonalities, the deep red variety is most associated with January. However, garnets range in color from deep red and dark pink/purple to yellow, orange, and several shades of green. You might even find an incredibly rare blue garnet.

Garnets popularly signify trust and friendship. Traditionally, this gem was believed to protect people during their travels. Due to its hardness, a garnet makes an excellent stone for jewelry intended for daily wear.

The rose gold chain perfectly complements the deep red garnet center stone.

Unlike other members of the beryl family, aquamarine doesn't have cleavage or inclusions. Thus, it makes a strong, durable gemstone for jewelry.

Historically, the birthstone for June was the pearl. This organic gemstone has a long history of jewelry use that continues to this day. Many myths and legends have grown around pearls, as well. However, alexandrite, a relative newcomer to the gem world, has taken its place on the modern list.

First discovered in Russia in the 19th century, alexandrite was named after the future Czar Alexander II. This incredibly rare gem can also change colors. Alexandrite appears green in daylight but changes to a purple-red color beneath incandescent lighting.

Alexandrite has no ancient meanings. However, some people associate it with heightened intuition and pleasure. Without question, natural alexandrites command extremely high prices per carat. If you opt for this modern birthstone, you may have to settle for a synthetic, but still very expensive, alexandrite.

July's traditional and modern birthstone is ruby. This gem's many symbolic associations include love, passion, wealth, and peace. In ancient times, people wore it as protection against evil and harm.

Although most associated with blue, sapphire comes in a wide variety of colors. In fact, this September birthstone, traditional and modern, occurs in every color except red. (Sapphire, by definition, is the non-red gem variety of corundum). Sapphires have many symbolic associations and a rich folklore. Traditionally, this stone was believed to protect your loved ones from harm. In the Middle Ages, Christian clergy wore blue sapphires as symbols of heaven. For many gem enthusiasts, these gems now symbolize wisdom, purity, and faith.

Durable sapphires make great gems for daily wear jewelry. Typically, pure blue stones or blue stones with a green or purple tint rank as the most valuable.

Once upon a time, before modern gemology, all yellow stones were considered topaz. In the early 20th century, gemologists defined topaz as a distinct gem species which included yellow as well as blue, pink, purple, and other varieties. So, the traditional November birthstone transformed into the modern version, yellow or golden topaz. However, you can pick the topaz color you like best for birthstone jewelry.

Another modern November option, citrine is an attractive yellow gem. Just keep in mind that while citrine (a quartz) and topaz are sometimes confused, they are distinct gem species. They also have very different price ranges.

A citrine in a rose gold twisted rope ring is a unique take on this November birthstone.
