Imagine holding a gemstone that glows with the vibrant green of a forest after the rain, sparkling with the fire of a thousand tiny diamonds. This is the Demantoid garnet, a rare jewel from Russia’s legendary Ural Mountains. But what truly makes it unforgettable is the delicate, golden pattern inside — the horsetail inclusion — twisting like a horse’s tail, proof of its natural origin and unmatched beauty.
In this article from brkogems, we’ll journey through the rich history of Russian Demantoid, uncover the secrets of its unique inclusions, and reveal why collectors around the world cherish this unique gem. If exceptional beauty and true origin speak to you, this story is made for you.
The Russian Mines: Birthplace of the Demantoid Legend
The Ural Mountains, among the most famous Russian gemstone mines, are a wild and ancient land, stretching between Europe and Asia. Their unique mix of minerals and old volcanic activity created the perfect home for a very special gemstone — the Demantoid garnet.
What makes these mountains extra special is how their natural conditions helped form the famous horsetail inclusions — delicate, golden patterns inside the stones that look like a horse’s tail. This feature makes Russian Demantoids truly one of a kind.
It was in the mid-19th century, deep in the rugged Urals, that miners uncovered this glowing green gem — a moment that marked the beginning of Russian Demantoid history.”It sparkled like fresh leaves after the rain, and soon word spread. Jewelers and nobles all wanted to get their hands on this rare treasure.

Even the Russian Tsars fell in love with the Demantoid. They used it to decorate crowns, necklaces, and royal jewels. For them, this gem was more than just beautiful — it was a symbol of their empire’s power and wealth.
Demantoids from other places like Namibia and Madagascar don’t have the same bright green color or the famous horsetail patterns. That’s why the Russian Demantoid is so prized and special among collectors worldwide.
Thanks to the unique nature of the Urals, the royal history, and its rare beauty, the Russian Demantoid isn’t just a gemstone — it’s a legend that carries the spirit of the mountains and the stories of a great empire.
What Is a Horsetail Inclusion – Nature’s Signature in Stone
When you look inside a Russian Demantoid garnet, you might notice something magical — a delicate, golden-green pattern. This twisting and turning pattern that looks like a horse’s tail is one of the most unique garnet inclusions. In fact, gemstone inclusions explained by experts reveal that this feature, called a horsetail inclusion, is a natural signature that sets these gems apart from all others.
Scientifically speaking, horsetail inclusions are tiny, fibrous crystals made mostly of chromium-rich actinolite (a type of amphibole mineral). These thin fibers grew inside the gemstone millions of years ago as it formed deep underground. The way they spread and twist creates that beautiful, shimmering pattern that collectors instantly recognize.
What makes this feature even more special is that it appears almost exclusively in Demantoid garnets from the Ural Mountains. No other Demantoid sources, like Namibia or Madagascar, have this distinctive horsetail pattern. This uniqueness helps experts and buyers confirm the gemstone’s true Russian origin — a natural proof of authenticity.
Types of Horsetail Inclusions:
Horsetail inclusions come in a few fascinating patterns.
- Classic Horsetail: Thin, needle-like fibers radiating outward with curved shapes.
- Curved Fibers: Shorter, tightly curved fibers forming intricate patterns.
- Fan-Shaped Inclusions: Fibers arranged in fan-like patterns.
- Clustered Fibers: Groups of densely packed fibrous minerals.
Horsetail inclusions not only prove the gem’s origin but also give it a unique sparkle and life. Like a frozen piece of Earth’s history, they enhance both its beauty and value in markets and auctions worldwide. These natural signatures turn each Demantoid garnet into a priceless treasure, cherished by collectors worldwide. Let’s explore how this unique feature enhances the gem’s allure and value.
