  • I’m not actually sure. Typically faceting uses water to keep the stone cool while grinding. The water would dissolve the sugar and the friction heat would melt and move the candy ever so slightly so I’d never get a perfect polish or accurate meetpoints. If an oil coolant was used, I’m not sure the stone would be edible after… And that doesn’t even touch on what a nightmare it would be to clean sugar out of my equipment.

    Conceptually, with a lot of foresight, you might be able to do a really crappy faceting of a piece of candy. Realistically it’s a nightmare idea and an expensive mess.




  • It’s not a silly question at all 😄 faceting is one of those rare hobbies to stumble across in the real world.

    For perspective, this stone took me about 8 hours to cut, so this little comment probably makes the execution sound simpler than it is. Most faceters use a diagram to cut which tells them the precise angle as well as location on the the stone to cut that angle.

    We glue our uncut stone to a stick, called a “dop”, to attach it to our angle machine.

    We have spinning discs, called “laps” that are basically like sandpaper but made with diamonds instead of sand. When we cut the stone we start at very low grit laps which will cut fast but leave behind deep, rough scratches, then we progress to finer and finer grit laps until the diamond scratches are so microscopic that to a 10x magnification the stone still looks flawlessly polished.

    We do this grinding technique to one half of the stone at a time, typically the pavilion (the backside of the gem) first and then the crown (top half) second.

    Crylos has actually posted a much more in depth how-to earlier in this community if you want to drive deeper into the rabbit hole of faceting.

    In this stone, the frosted facets are actually un-polished areas of the stone, so the snowflake you see is actually very fine scratches that aren’t bouncing light correctly, creating the “line” appearance. There’s multiple facets on the crown, so it is bouncing the “line” appearance through different angles, making it look way more complex than it actually is.

    Here’s a photo of the frosting lines on the pavilion. Deceptively simple compared to what you see on the final product, isn’t it? 🤭

  • Based on the article, the device will host actual kidney cells - I’m sure it won’t be as effective as having your own original kidney, especially in it’s early prototypes, but hopefully it’ll be better than mere dialysis.

    Even if the device was just a glorified portable dialysis machine though, that would still be a significant quality of life improvement for those on dialysis. With dialysis you’re locally tethered to the dialysis clinic because you need weekly treatments, until you eventually die or win the kidney lottery. With a portable machine you could hopefully travel, see the world and visit family more.

    Be kind to your kidneys everyone, drink enough water! You don’t want a life without efficient kidneys.
