New Localities: Enjoy Sunny Yellows From Mexico

Spring is here and the sun is finally out for longer! As the icy blues from EarthWonders newsletter issue 5 and blog post about blue fluorite - is it too good to be true - were really popular, we decided to focus on sunny yellows and refined localities across Mexico. Out of almost 5000 specimens 650 are looking for a new cabinet to call home! Can find your next buy in one of these localities?

See what else we have in Mexico mines including some amazing cumengeite and don't forget to like and comment!

Email or Instagram us your favourite localities and if you can't find them on EarthWonders we will work on them next!

Ojuela Mine, Mexico - Legrandite

The Ojuela mine in Mapimí Municipality, Durango, Mexico produced specimens of many different species, including Ojuelaite named after, well, the Ojuela mine! The mine is more famous for the holy grail of rare mineral collectors - Legrandite. The first occurrence of the species was described from the relatively nearby Flor de Peña Mine and named after a belgian miner who collected the first specimens -  Louis C. A. Legrand. No other locality producing Legrandite matches it in colour - the electric lemon yellow is unique to the Ojuela mine. Most notable specimens of legrandite stay put in private collections and museums for decades.

Ojuela Mine, Mexico - Adamite

Ojuela mine is the most famous locality for Adamite and produces yellow-green pinwheel-shaped specimens with amazing luster often growing on a limonite matrix. If you're not impressed with how gemmy it is in daylight - the exceptional UV fluorescence will win you over. Check out the fluorescence images for these specimens in the EarthWonders gallery.
