As one of the oldest gemstones known to man, garnet has inspired many legends and popular associations with vitality, love, and friendship. Commonly associated with the color red, it is both the traditional and modern birthstone for January, as well as the gemstone that represents the second wedding anniversary.

Learn all about January’s birthstone from our guide below, which includes the history, properties, and varieties of garnets.

What is Garnet?

Frequently mistaken for ruby due to its deep red color, garnet is the collective name for a group of minerals that possess the same physical properties and crystal forms but differ in their chemical composition. The diversity of these mineral species means that garnets are not only available in red but come in a wide array of other colors as well, including orange, yellow, green, and blue.

Fun fact: The name ‘garnet’ comes from the Latin word for pomegranate seed.

Some of the earliest examples of garnet jewelry have been unearthed from Egyptian tombs dating as far back as the Bronze Age. Other examples date back to the Middle Ages and include garnet signet rings and other jewelry from ancient Greece and Rome. The Victorian era produced some of the most beautiful garnet jewelry pieces, with clusters of tiny red gems forming part of a larger statement piece.

The widespread popularity of this gemstone throughout ancient times is likely owed to its perceived supernatural ability to protect the wearer from harm. As such, garnet has been worn as a good luck charm or talisman by people from cultures all over the world.

Today, the January birthstone is still as popular as ever and can be found in a wide range of jewelry designs.

Physical Properties of Garnet


As mentioned above, most people associate the January birthstone with a deep red color. However, garnet is actually available in almost every color on the spectrum, from brown to orange, to yellow, to green. There also exists a variety of color-changing garnet from countries like Tanzania, Kenya, and Madagascar. These remarkable gemstones transform from blue in fluorescent light to a deep purple hue in incandescent light.


Garnet has a medium hardness of 6.5 to 7.5 on the Mohs scale, meaning it is prone to scratches. That being said, garnet is not a brittle gem and is still suitable for daily wear. It does not chip easily and holds up well in a variety of jewelry settings.

Healing Properties of Garnet

Since ancient times, red garnets have symbolically been associated with a person’s life force and are thought to possess many healing properties.

In a metaphysical sense, red garnet gemstones are said to cleanse and revitalize the energy, bringing about mental clarity and boosting creativity. The January birthstone also balances the sex drive and inspires love and devotion.

Varieties of Garnet

There are over 20 varieties of garnet. However, only five are commercially important. There is a sixth, uvarovite, but this species is extremely rare and any facetable material is usually too small to cut.

Here is a brief overview of the six main species of garnet:

  • Almandine: Also known as almandite, this is the most common gemstone in the garnet family. Almandines are available in a wide array of colors, including the dark red variety commonly associated with this gemstone.
  • Pyrope: Chrome pyrope garnets can exhibit a deep red hue that rivals rubies. However, these stones can have a very dark saturation.
  • Grossularite: Grossular garnets occur in every color, including colorless, except blue. Unlike other garnets, they are rarely red or dark in tone. Their light to medium saturation and vibrant hues make them ideal for any type of jewelry. Tsavorite garnet is an emerald-green grossularite that can command high prices, while hessonite garnets (nicknamed ‘cinnamon stones’ for their brownish-red color) are generally on the lower end of the price range.
  • Spessartite: Also known as spessartine, this is a somewhat rare variety of garnet. They are typically orange, though the exact color and saturation can vary from one stone to the next. Mandarin garnets are a highly sought-after member of this species, exhibiting a striking orange color that’s hard to miss.
  • Andradite: Possessing the highest refractive index of all garnets, andradites have even more fire than diamonds. This characteristic, combined with their rarity, makes andradites one of the most highly-prized varieties of garnet. Demantoid garnet is a member of this species.
  • Uvarovite: The rarest species of garnet, uvarovites exhibit a rich, dark green hue that rivals emeralds.

Garnet Blends

In nature, most garnets don’t form as a single pure species. In other words, they consist of two or more varieties blended together. For pyrope garnets, the purest gem-quality specimen ever found contained around 83% pyrope. The other 17% was made up of other species of garnet. The same is true for almandine and grossular garnets. However, some specimens have been found from the spessartite and andradite varieties that were as high as 95% pure.

The following species are known to blend:

  • Almandine – pyrope
  • Almandine – spessartine
  • Grossular – andradite
  • Pyrope – spessartine

Due to the tremendous range of overlapping between species, it is not possible to identify a garnet based on its color alone. Therefore, note that the information contained in the following section is for reference only.

Reddish Purple and Pink Garnets: Rhodolite

Rhodolite garnet has a distinctive reddish-purple hue that’s sure to resonate with many of those with a birthday in January. These beautiful gems also occur in shades of pink and violet, so you’ll have no shortage of options when choosing a gem from this variety.

Orange Garnets: Spessartite

If you find yourself drawn to warm colors, the orange to reddish-orange gems from the spessartite variety might appeal to you. Known as Mandarin garnets, these stones are highly prized for their vivid orange hue.

Yellow Garnets: Andradite and Hessonite

Though best known for the green garnet variety demantoid, andradite is also available in a bright yellow hue sometimes called topazolite. Similarly, hessonite garnets, which are widely known for their cinnamon-red color, are also available in attractive shades of yellow.

Green Garnets: Tsavorite and Demantoid

If you’re looking for an exciting alternative to the traditional red color that most people associate with the January birthstone, consider the rare tsavorite or demantoid garnet. Tsavorite garnet comes in a rich green hue that’s easily mistaken for emerald, while demantoid garnets can exhibit a fire that exceeds diamond.

Color Change Garnets

Though the phenomenon of color-changing gemstones is most commonly associated with alexandrite, a member of the chrysoberyl family, a variety of color-changing garnet has also been discovered in recent decades. These remarkable gems have been found in the countries of Kenya, Madagascar, and Tanzania, and transform from blue in daylight to a rich reddish purple in incandescent light.

Garnet January Birthstone Alternatives

If the garnet birthstone just doesn’t resonate with you, rose quartz is the alternative birthstone for January. With its blushing pink hue, this variety of quartz is often viewed as a universal symbol of love and will be popular for years to come.
