  5. We have a #MinCup25 champion!!

    Congratulations, #Kyanite!

    After eight years of competing, another few hours to verify votes was nothing, right?

    Amazing first run, #Tugtupite, and better luck next year.

  9. 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 or samples, but many others for sure. There's always a good representation of Canadian and Quebec localities.

  14. 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

  22. #Dioptase is an amazing colour-changing pleochroic goddess of a queen that looks as stunning as #Tugtupite - or more so.

    She well deserves a crown in #MinCup25!

    mineralcup.org/2025/vote

    An international 'crystal water' stone of mystery, it also went by the names of #achrite, #emeraudine, copper emerald or #kirghisite 🥷 👑

    An amazing looking explosion of a starburst of a flower shape, The centre a turquoise colour, and the edges of the "blades" or petals of the flower in darker blueish violet colour, behind it darker still.
    The lowest part white with flecks of yellow or gold, so it reminds you of space with its haze making for the starburst thought.

    Very dark green lustrous dioptase crystals that look almost black. This is a night queen that sparkles. And makes for sparks if you heat it up, being pyroelectric AND phleochroic, changing colour depending on how you look at it.

    #CopperSilicate (CuSiO3·H2O). Its lustre is vitreous, glass-like, to sub-adamantine, so talking Wolverine shit here, folks. 😅

    The Poudrette quarry is the type locality of 73 minerals, 35 of which have not been found elsewhere. It's an IUGS Geoheritage site. At this site alkaline magmas intruded platform sediments during the Cretaceous.

  34. Crown Emerald Copper, Desert Queen Dioptase!

    mineralcup.org/2025/vote/r4m02

    Please vote for the pyroelectric, HOT desert mama! It's so amazing it can look like moss but is electric if you heat it up 😲

    So, did someone call #electric #Mosstodon? The most arid deserts in the world have none, but grow moss-like dioptase to make up for it. The world's amazing, so spread the love & vote!
    Forbidden #broccoli or green #cauliflower?

    Dioptase was first mistaken to be emerald and gets its colour and toxicity from copper. Hence, Emerald Copper and Desert Emerald nicknames! Although it's toxic - no licking! 😅 - the vivid green tones make it great for healing & the heart. 💚💎🧡

    Here's some different mossy shapes to spot in different photos, if you want to look toward the ground instead of what you see in clouds! Thanks for voting!

    We can get a #piezoelectricity versus #pyroelectricity battle for the ages! It's * #ELECTRIC * ;P

    Pressure or fire, heating things up to get zappadelic, gotta love that.

    Better yet:
    "As mentioned in the introduction, there is a profound relationship between pyro and piezo sensors: Every pyroelectric crystal is also a piezoelectric crystal (but not vice versa)."
    Heating leads to expansion of the crystal lattice, and a measurable electric voltage.
