help Poudretteite FAQ

How rare is gem-quality poudretteite?

Poudretteite is considered one of the rarest gemstones on the entire planet, with only a tiny handful of faceted stones known to exist. Because of its extreme rarity, it is highly sought after by elite mineral collectors rather than commercial jewelry designers.

Where was the first poudretteite crystal discovered?

The mineral was initially discovered in the mid-1960s within the Poudrette Quarry located at Mont Saint-Hilaire, Quebec, Canada. It was named after the Poudrette family, who owned and operated the quarry where this unique pink cyclosilicate was found.

What is the Mohs hardness of poudretteite?

Poudretteite has a Mohs hardness rating of approximately 5.5. Because it sits right in the middle of the scale and possesses perfect cleavage, it is quite a soft and fragile stone that would be incredibly difficult to wear safely in an everyday ring.

Are there poudretteite gems mined outside of Canada?

Yes, while Canada was the original source, a very small number of gem-quality poudretteite crystals were later discovered in the early 2000s. These exceptional pink specimens were found in the famous Mogok Stone Tract region of Myanmar (Burma).
