The Rare Beauty of Demantoid Garnets
Demantoid is a type of garnet that is known for its exceptional quality and rarity. It is a variety of the mineral andradite, which is a type of grossular garnet. Demantoids are found in only a few locations around the world, including Russia, Sri Lanka, and Madagascar.
Demantoids are prized for their vibrant green color, which can range from light yellowish-green to deep green with a hint of blue or purple. They also have a high dispersion, which means that they have a unique ability to split white light into its component colors, creating a sparkling effect known as "fire." This fire is particularly noticeable when the stone is moved under different light sources.
Demantoids are considered to be one of the rarest and most valuable types of garnets, and they are highly sought after by collectors and gem enthusiasts. They are often used in high-end jewelry and are prized for their beauty and rarity.
