if this is indeed what i think it is, how common is it? like if all the known worlds unheated sapphire/spinels were 2,000 in population and this was one of them? ( its presently in the mail, but will be here by tuesday. )
yes. to rephrase my question. thats a sapphire. on the edges are bits of spinel. is this a common occurance, and if its not, what are the population numbers relating to this happening?
What you're seeing is color zoning. I don't think this is a spinel inside a sapphire
yes. i too am vey familiar with colour zoning. but when your lattice is turned the other way, its two minerals
Why do you think it's a spinel inside a sapphire?
I don't see how those pics show you anything about lattice or multiple minerals
thats not my question. thats YOUR question. my question was, IF its what it is, spinel embedded into sapphire, whats the population of this puppy?
I know tje company you purchased from and they do all of this testing. So I think you are convincing yourself you got something rare when you didn't.

I don’t think one can answer that question with any realistic degree of credibility. Spinel inclusions in a sapphire are possible I suppose, but a “merged” lattice sounds unlikely. The gem you posted seems to clean for that, I would expect some “mess” at the point in which sapphire turns into spinel by the presence of magnesium in the lattice. It looks too clean to me, but I am no gemologist so take my words with a grain (or two) of salt
No, but you can have microscopic spinel inclusions in sapphire.
I've never heard of a melded spinel/sapphire.
What you have is called color zoning, very common and what the trade calls Parti sapphire if they're pleasant looking.
The question you should be asking is if the stone is natural at all.

Can you draw on the photo you have provides where you feel the bits of spinel are located on the sapphire? I’m not seeing it. Circle them?
I don’t think mineral inclusions in sapphire are uncommon - but don’t know specifics or stats.

@Lexililac
Maybe they know?
Can I ask what clues (other than the color from the pic) guide you to the conclusion it is coexisting sapphire and spinel that’s zoned like this is?
The vendors listing itself?
yes. i have a kashmir like that. but its marble and kashmir inside kashmir. or gold inside tourmaline. or platinum and uranium inside diamond. and no, i donts question the nuturalness of the stone. i did not purchase it from india of thailand. i purchased it from someone who purchased it from ceylon
