Demantoid is definitely one of those under-the-radar treasures — rare, especially in fine jewelry. If you want to explore it more, check out Tsarina Jewels https://tsarinajewels.com/ . Their gemstones and high end jewelry feature Russian demantoids, known for their intense green tone and a fiery sparkle called dispersion. What sets demantoid apart is how it handles light — you get this internal rainbow flash you usually only see in diamonds. Plus, Russian demantoids often have unique inclusions called “horsetails,” which are actually sought after. It’s a gem with both beauty and story.
