How to distinguish between obsidian and black onyx
Appearance: Obsidian is often characterized by a glassy and smooth texture, with no visible crystals or grain. Black onyx, on the other hand, may have a slightly more matte or polished appearance and can sometimes display visible banding or stripes.
Hardness: Obsidian is a relatively soft stone, ranking 5-5.5 on the Mohs hardness scale, meaning it can be scratched or damaged more easily than some other gemstones. On the other hand, Black onyx is harder, ranking 6.5-7 on the Mohs scale.
Weight: Obsidian is generally denser and heavier than black onyx. You can test this by comparing two stones of similar size and observing which one feels heavier in your hand.
Conductivity: Obsidian is not a good conductor of electricity, while black onyx is. You can test this by rubbing the stone with a wool cloth or comb to create static electricity and observing whether or not it attracts small particles like dust or hair.
Origin: Obsidian is formed from volcanic activity, while black onyx is a variety of chalcedony, a mineral that forms in sedimentary rocks. If you know the source or origin of the stone, this can help you distinguish between the two.
It's important to note that even with these characteristics, it can still be difficult to differentiate between obsidian and black onyx, especially if they are polished or have similar appearances. Consulting a gemologist or expert in gemstones may provide additional insight and assistance in identifying these stones.

thecrystalkeepers on ig
butterflies pictured (as far as i can tell, in order):
chocolate solider (junonia iphita), postman butterfly (heliconius melpomene), malachite butterfly (siproeta stelenes), blue moon butterfly (hypolimnas bolina), another two malachites, some type of lacewing butterfly (the coloration is throwing me off), another blue moon butterfly, two more malachites, and i think the top butterfly in the last gif is the chocolate solider from the first gif, and the one on their hand looks like another blue moon butterfly.
if i got any of these wrong, please let me know!
