Demantoid Garnet Value

Demantoid Garnet is one of the rarest garnet varieties and is highly sought after by gem collectors, jewelers, and enthusiasts. It is considered the most valuable garnet variety and is known for its exceptional brilliance and dispersion (often referred to as "play of color"). Demantoids with horsetail inclusions, wavy golden, and fibrous inclusions are highly sought after by collectors.

 

Demantoid Garnet Color

Demantoid Garnets are known for their mesmerizing green colors, ranging from moss green to vibrant neon green or yellowish-green. Their dispersion of color, often referred to as "play of color," is highly appreciated and distinguishes them from other green gemstones.

 

Demantoid Garnet Sources

Russia was the primary source for Demantoid Garnets for a long time, with notable mining locations including the Ural Mountains region, the Koryakskoe plateau, and the Kola Peninsula. Since the 1990s, Namibia and Madagascar have become important sources for Demantoid Garnets. Italy, particularly Ala in Piedmont and Val Malenco in Sondrio Province, also produces Demantoids. Other notable sources include various locations in Africa, particularly Namibia, and Russian Demantoids.

 

Demantoid Garnet Properties

Demantoid Garnet was discovered in Russia in the early 19th century and gained its name due to its diamond-like appearance, primarily because of its exceptional brilliance and dispersion. It was highly popular during the Belle Époque period and was favored in Art Nouveau jewelry. Demantoids have greater brilliance and dispersion than diamonds and other green gemstones like emerald and peridot. Horsetail inclusions of byssolite or chrysotile, typically with a golden color, have long been considered diagnostic for identifying Demantoids. However, it's worth noting that horsetail inclusions can also occur in other stones and not all Demantoids have them.

 

Demantoid Garnet Care


Demantoid Garnets have a hardness of 6.5 - 7.5 and no cleavage, making them durable gemstones suitable for various types of jewelry, including everyday wear and engagement rings. To clean Demantoid Garnets, use warm soapy water and a cloth. Avoid using chemicals or other cleaning methods that could potentially damage the stone.

Demantoid Garnet's rarity, exceptional brilliance, and unique dispersion make it a highly coveted gemstone among collectors and jewelry enthusiasts.
