Benitoite is a rare silicate mineral that is typically blue in color and demonstrates outstanding transparency and brightness when cut. It was first discovered in 1907, and gemstone quality benitoite has been found only in San Benito County in California, US, but is currently no longer mined, which makes benitoite's price particularly high.
It's not used in jewelry very often, partially due to its low hardness on the Mohs scale (6-6.5), and partially due to its rarity. Benitoite specimens are highly prized for their exquisite appearance and uniqueness, and most of them belong to gemstone collectors. Another remarkable property of benitoite is its fluorescence under shortwave UV light.
Benitoite's value depends on a number of factors, and its rarity makes it one of the most expensive minerals per carat weight. Pieces larger than 3 cts are very unusual, as this mineral doesn't form large crystals. Other factors, such as color, cut and clarity also play a role, and are all reflected in benitoite's value chart (available to registered users).
