The Garnet Family: A Spectrum of Radiance

The Garnet Family: A Spectrum of Radiance


1. Spessartine Garnet

Spessartine Garnet, often known as "Fanta" garnet, is widely recognized for its vivid color that closely resembles the bright orange hue of the popular fizzy drink. With a high refractive index and warm hues, Spessartine exudes a sense of elegance with fiery intensity, reminiscent of sweet summer citrus. The rich, vivid orange hue of high-quality Spessartine is highly prized among collectors.

2. Grossular Garnet

Tsavorite, a distinctive green variety of Grossular Garnet, contains trace elements of chromium and vanadium. The term “Kajani” (meaning “green” in Swahili) represents Tsavorite’s finest hue—a vibrant, natural green that reflects the essence of nature.

With fewer inclusions than emeralds, a high refractive index, and a significantly lower per-carat price, it’s no surprise that Tsavorite quickly captured the attention of the jewelry world. Before long, it graced the showcases of major jewelry houses and became one of the most popular choices among green gemstones.

3. Pyrope Garnet

Pyrope Garnet can range in color from brownish-red to purplish-red, and occasionally even appear nearly black, with the highest quality exhibiting a beautiful purplish-red tone often referred to as “Rhodolite.”

This variety of garnet exhibits a high refractive index and dispersion, emitting a mesmerizing sparkle. If you happen to love this reddish-purple colour but do not wish to break the bank, I would highly recommend giving the Rhodolite a try.


4. Almandine Garnet

Gem-grade Almandine Garnet is typically found in shades of red, from brownish-red to pink and orange-red. It often contains needle-like inclusions, which, when cut en cabochon, create a stunning star effect—appearing as though a starlit sky is held within the gemstone.

5. Demantoid Garnet

Demantoid Garnet, a highly esteemed member of the andradite Garnet family, is known for its rarity and exceptional quality.

Typically found in ultramafic rocks, Demantoid’s high refractive index, clarity, and vibrant color are enhanced by trace elements of chromium, which produce a complex and intoxicating green hue. They are also known for their unique "Horsetail" inclusion, which makes them really stand out from the rest of the members of the Garnet family.

With high dispersion, Demantoid alternates between a diamond-like brilliance and a glassy luster, revealing its beauty with every shift of light.
