Enchanting Emma Eggs or Seer Stones in amethyst, smoky quartz, crystal quartz, and rose quartz.
These stones are frosty-looking and cloudy on the back but clear and polished in the front. They are also used as scrying stones because the transparent cross section can be peered into for messages in markings and formations in the stones' cores. So they are great to use as divination tools and beautiful as crystal decor.
If you absolutely obsess over and love sweet chewy Japanese mochi, seer stones resemble these, as well. The pastel gemmy, candy-colored interior that is revealed at the top looks like someone took a clean bite or slice out of a fruity-flavored and delicately sweet piece of mochi with a starch powder coating.
Just goes to show how yummy the beauty of seer stones is, like magical candy eggs.
