differences
  • earthy green witches: this crystal is amazing and has so many wonderful properties! it took the earth thousands upon thousands of years to create it. we use it for healing, protection, and all sorts of wonderful magickal stuff. don't you just love the color and grain of it?!
  • me, a sea hag: that there rock sure is purdy.

anonymous asked:

do you think lapis has gold flecks that would perhaps be visible in a more complicated design?

nah. lapis with little-to-no visible pyrite (and calcite) is often regarded as more valuable, and lapis herself is implied to be some kind of aristocrat. if they wanted to include pyrite flecks, they could have, but more valuable lapis often looks more like this:

also, from a design stance, i don’t think it’s a good color scheme outside of very specific “here’s lapis and Only lapis” settings. and i’ve just been… totally desensitized, after every single lapis ~recolor looks like it’s based on low-grade raw lapis. i understand why one would assume gold color = valuable, but that’s just not always the case.

I’d like to clear something up that I’ve noticed a lot among gemstone using witches. People keep posting psa’s about “fake gemstones” and while some stones really are made of glass and you’re being scammed, heat-treated citrine is not one of these. I’ve studied gemology at a tertiary level for my jewellery degree, so let me explain.

Does anyone know the difference between an amethyst that’s been heated in a lab and a naturally occuring citrine? Not a damn thing. Literally. Every single naturally occuring citrine used to be an amethyst. Amethyst becomes citrine when exposed to extreme heat, such as a lava flow or nearby magma chamber or something like that. The only difference with lab citrine is that they take an amethyst and blast it with man-made heat rather than dunking it in some lava. The speed with which this happens is why there’s a colour variance between naturally occuring citrine and lab citrine, but for all intents and purposes, they’re exactly the same.

Still, for certain things it’s good to be able to differentiate, as natural citrine is much more anchored in earth and fire, but honestly? Bury your lab citrine in your back yard for a few days and it’ll re-anchor itself. Also, a blast furnace may not be a lava flow, but it’s sure as hell gonna anchor something to the fire element. Admittedly, if you want something to connect you to a volcanic deity probably go with the natural citrine if you can, but I digress.

basically, stop telling people lab citrine isn’t genuine. it’s absolutely a real citrine.

I recently got caught up on the glass scientist Web comic by Sabrina Cotugno @arythusa after listening to the Jekyll and Hyde musical and being reminded of how much I loved it! I got inspired to draw my own Rogue scientist Cassius!
She is a bio- minerologist which basically means she works with minerals (such as gems, gemology being a sub category) and since the supernatural as well as scientific exist in this story she has learned to create golems (living beings of stone).

✨🔮 Is this real life?! Thanks to the Australian opal master @keithcler, I now own this solid sphere of Australian boulder opal. I have been after something like this for so long and can’t believe one has finally joined my crystal ball collection. Thank you, Keith! 🔮✨ I’m off to work on new pieces. Hope you’re all enjoying your weekend so far.
