@lizzydm26 The above thread discusses a bit of pricing in spinel, so if you haven't come across it, I believe it will be useful to you.
From what I know, spinels aren't heated as the process doesn't really do anything for them. I imagine since heating is such a common treatment for many other gems, vendors prefer to state "unheated" when listing their spinels.
What does happen to spinels, though, is oiling, and that one often comes undisclosed. From what I understand it's also a treatment commonly missed by small local asian labs, so that's one thing to consider when buying from etsy or IG. Another is that these places have a higher concentration of sellers who would rather not disclose clarity issues. The price is lower, but it's only worth it if clarity isn't a top priority for you.
