Found only along the Charo River in the Sakha Republic of Siberia, its sole commercial source anywhere, charoite is a rare silicate whose swirling lavender-to-purple patterns make every polished piece unique. A fibrous, interlocking crystal growth produces its violet, lilac, and white swirls, and at 5.0 to 6.0 on the Mohs scale in the monoclinic system it is soft enough that cabochons and carvings suit it best. It was discovered in 1978 and named for the river where it occurs. Despite its rarity, charoite remains a budget-tier semi-precious stone, and its instantly recognizable appearance has made it a favorite among collectors and jewelry designers alike.
