Musgravite is an extremely rare and valuable gemstone that belongs to the taaffeite mineral group. It was first discovered in 1967 in the Musgrave Ranges of South Australia, from which it derives its name. Initially mistaken for taaffeite due to their similar properties, musgravite was later identified as a distinct mineral due to differences in its crystal structure and chemical composition. It is composed of beryllium, aluminum, and oxygen (BeAl₃O₁₂), with traces of iron, zinc, and magnesium influencing its color.Musgravite exhibits a color range that includes grayish-green, purple, violet, and bluish-gray tones, with some specimens displaying pleochroism, meaning they can show different colors when viewed from different angles. It crystallizes in the hexagonal system and has a hardness of 8 to 8.5 on the Mohs scale, making it quite durable for jewelry. However, due to its extreme rarity, musgravite is primarily found in private collections rather than commercial jewelry pieces.For decades, only a handful of musgravite specimens were known to exist, making it one of the rarest gemstones on Earth. Since its discovery, small deposits have been found in Sri Lanka, Greenland, Madagascar, Antarctica, and Tanzania, but fine-quality facetable musgravite remains exceptionally scarce. Because of its rarity, it is considered more valuable than diamonds, with top specimens fetching prices of over $35,000 per carat. Musgravite’s scarcity, combined with its unique optical properties and durability, makes it a highly sought-after gemstone among elite collectors and gemstone enthusiasts.
