The Montreal Gem and Mineral Show is happening at the end of the month in the main convention center (Le Palais des Congrès).
No guarantee of fantastic #Tugtupite or #Kyanite samples, but many others for sure. There's always a good representation of Canadian and Quebec localities.

While blue kyanite is used in jewelry, porcelain & pottery glazes, plus gets physics points as an index mineral, it’s the extraordinary ‘reindeer blood’ tenebrescent, & phosphorescent tugtupite “King of Fluorescent Minerals” which is also a gem, gaining both art and physics points for me. #MinCup25
Vote tugtupite in the Mineral Cup 2025 finale here:
A tough call for the #MinCup25 semi-final but I think I have to give dioptase the arts vote as a pigment since ancient times (i.e. on Neolithic sculpture, Asian murals & Russian icons), though ‘reindeer blood’ tenebrescent, & phosphorescent, tugtupite “King of Fluorescent Minerals” is also a gem, gaining both art and physics points from me.

Rhodochrosite's "Meat rock" Mineral Cup victory last year necessitates two vegetable wins! Why? So we get our MEAT & TWO VEG! 😁
https://www.mineralcup.org/2025/vote/r4m02
Eat your veg! Greens are good for you! You wouldn't eat Rudolph, and blood products are icky, whether reindeer's or other blood. Vote for #ForbiddenBroccoli, baked in #ForbiddenPie! 🥦 🥧
More photos in the post above and the cup tags. Please vote before midnight UK time, or within the next 18,5 hours, and thank you to Desert Queen voters!
