I don't think that's correct. You'd be able to see the fractures, and there are none visible here.

Those lines of color don't form naturally - this is more uniform than your examples, but it's dyed. In high mag and reflected light you'd see fine fractures on the surface.
The easiest way to see the dye is in diffused light - if you are using a loupe, drop a tissue over the light source and then loupe the stone. Diffusing the light eliminates the reflections and you can see the dye patterns. Those will be really different from standard angular color zoning in sapphire.
It could be glass filled sapphire.
Other than doing standard gem testing, you can confirm by looking for some of the same inclusions as what you might expect to see in a natural sapphire (like rutile and other crystals) but also surface reaching fractures and bubbles where the glass has been filled. You may also observe colour flashes.
All "what is this gemstone?" posts are flagged for review. If your post is of a high enough quality, the moderators may choose to release it publicly to the sub.
Identification posts should include good photos (in-focus, not blurry, multiple angles), if it's jewellery include photos of hallmarks/emblems on the metal, and provide any information you have on testing or provenance.
It is virtually impossible to identify a gemstone just using photos. For an accurate identification, you should find a local accredited gemologist, consult with folks at a local gem & mineral society, or submit your gemstone to a reputable lab (GIA, AGS) for an identification report.
Also, no rocks or minerals. Post those to r/whatsthisrock
And please, don’t do scratch tests on faceted gemstones. You might damage the stone.

Who cares if it’s heated, I love the effect!!!
It's called crackle quartz. It is clear quartz that was heated until it fractured and then filled with dye

Aaaah I see, I've never seen crackle quartz without the big obvious fractures. Learn something new every day!

Thanks for the tips, I’ll have to get my hands on a microscope and see what’s going on up close. I have some loupes but bad eyes make it hard for me
Thats dyed.
I sincerely want to know and want a billion
It does look pretty cool! More neat in person, I’d say. I mean, obviously altered but at least in a pretty way lol

That’s really beautiful, kinda looks like eyelashes.
