The traditional January birthstone is garnet. Garnets are a group of silicate minerals that come in a variety of colors, including deep red, reddish orange, and green. The name “garnet” comes from the Latin word “granatum” meaning “pomegranate seed,” in reference to the red color many garnets exhibit. Garnets have been used in jewelry and as gemstones for thousands of years, and are historically associated with healing, protection, and strength. January’s deep red garnets are thought to inspire peace, good health, and prosperity as we start the new year.

While the selections have evolved across cultures, the tradition of wearing birthstones remains popular today.

Physical properties of garnet
Garnets belong to a group of silicate minerals that crystallize into cuboid forms. The most common garnets have the following physical properties:
| Property | Description |
|---|---|
| Chemical composition | Silicates of aluminum, iron, magnesium, manganese, and calcium |
| Crystal structure | Cubic |
| Hardness | 6.5 – 7.5 on the Mohs hardness scale |
| Specific gravity | 3.5 – 4.3 |
| Refractive index | 1.71 – 1.94 |
The wide range in chemical composition allows garnets to form in many colors across the color spectrum. The most prized garnets have high clarity and vivid, saturated hues.
Types of garnet gemstones
There are over 20 varieties of garnet minerals, which are differentiated by their chemical makeup and color. The most significant types of garnet gemstones include:
| Garnet Variety | Color | Key Facts |
|---|---|---|
| Pyrope | Red, purple-red | Magnesium aluminum silicate, historically called “carbuncle” |
| Almandine | Red, reddish-brown | Iron aluminum silicate, commonly used in jewelry |
| Spessartine | Orange, yellow-red | Manganese aluminum silicate, rare and valuable |
| Grossular | Yellow, green, orange, brown | Calcium aluminum silicate, referred to as “grossularite” |
| Andradite | Yellow, green, black | Calcium iron silicate, includes rare “demantoid” green garnets |
| Uvarovite | Green | Calcium chromium silicate, bright green color is highly prized |
The deep red of pyrope and almandine garnets are most linked to January’s birthstone tradition.
Where are garnets found?
Significant deposits of garnet minerals have been discovered across the globe, including:
- The United States – Idaho, Montana, California, Connecticut
- South Africa – large pyrope and grossular garnet mines
- India – famous for almandine deposits and gemstone cutting
- Sri Lanka – known for fine red and pink gem garnets
- Russia – key source for rare demantoid and uvarovite garnets
- Australia – alluvial garnet deposits in Idaho and Montana
- Brazil – significant spessartine garnet discoveries
- Madagascar – small but high quality garnets found here
Additional deposits likely remain undiscovered in other parts of the world. Garnets form under high pressure and temperature deep underground, brought close to the surface through geological activity.
How are garnets classified for the gemstone trade?
Gem-quality garnets are classified using a letter-number system indicating their color, saturation, and tone. The standard classifications are:
| Classification | Definition |
|---|---|
| A1-A2 | Pure red color, slightly dark or light tone |
| B1-B2 | Slightly purplish red, medium-dark or light tone |
| C1-C2 | Purplish red, medium-dark or light tone |
| D | Purplish red, very dark tone |
| E | Bluish red |
The numeric digit after the letter grade indicates light (1) or dark (2) tone. Top quality January birthstone garnets are A1 and A2 classification.
How are garnets valued and priced?
Garnets are moderately valued gemstones, more affordable than extremely rare gems. Factors affecting garnet prices include:
- Color – Vivid red and green garnets command higher prices. Dark tones are preferred.
- Clarity – Garnets with high transparency and fewer inclusions have greater value.
- Cut – Precise cutting impacts brilliance and is factored into pricing.
- Carat weight – Larger garnets are exponentially more rare and expensive.
- Variety – Demantoid, tsavorite, and uvarovite are exceptionally rare.
Well-cut 1-carat red garnets typically range from $75 to $300 per carat. Larger stones over 5 carats can cost several thousand dollars per carat.
How should garnets be cared for?
Although garnets rate 6.5-7.5 in hardness, they still require some care. Recommendations for garnet care include:
- Store garnets separately from other gems to prevent scratching.
- Clean with warm water, mild dish soap, and a soft brush periodically.
- Avoid exposing garnets to harsh chemicals like bleach, acids, or ammonia.
- Ultrasonic and steam cleaners are safe for garnets.
- Have garnet jewelry inspected annually and re-set as needed.
With occasional cleaning and inspection, January birthstone garnets can remain beautiful for many years.
