Does a black inclusion make it likely a ruby is natural?

[kgizo]

Recently purchased this brooch from a local place. It is mine cut diamonds in platinum topped gold. There is a black inclusion on the underside of the ruby. Wondering if this gives any indication if it is a natural ruby instead of synthetic.

Very pretty! Can we see the back, including the hinge, pin, and clasp? That might be a good clue to the age, which might give more info about whether it might be natural.

Very pretty brooch!
Not conclusive of course
But my GIA Tanzania no heat Ruby has a few spots kind of like that

Thank you, here are pics of the back and clasp. Let me know if you need any more pics.

i love it !
how do you plan to wear it ?
on a coat ?
or are you repurposing it into a pendent ?

Stunning! Love love love. That wasn’t helpful, but true...

Gorgeous! Going by the style of clasp, the design, and the mix of gold and platinum, I would guess it was made around 1900. That's around when synthetic rubies big enough for jewelry were first manufactured, but I don't think they were very common until a little later, so I continue to think yours is probably natural. That is a really elegant brooch in beautiful condition. Natural or synthetic, it's glorious.

I’m inclined to consider it a natural ruby.
It’s a beautiful colour too.
the whole brooch is exquisite, the workmanship is fabulous. Such a fine and elegant piece, I do so hope you get it out and about often,

I believe natural rubies sometime have inclusions of blue sapphire. I am not someone who knows much about rubies though, so please take that with a huge grain of salt.

It's very beautiful. Enjoy your lovely pin!

Thank you! I plan to wear it as a brooch. If I don’t think it’s getting enough wear I will convert to a pendant as that is a good idea.

That is really helpful info about the history. I’m always curious about vintage jewelry and when they don’t have any stamps or clues it’s a little disappointing so I appreciate your insight about the brooch.

Thank you. I admire your collection so your kind words mean a lot.

That is interesting and new to me. It makes sense so I’m off to see if I can learn more. Than you!

Fluorescence is so cool!

Wow, what a special piece. I love moon motifs and that is just soooo delicate and lovely.

Absolutely no help to offer, but it is stunning!

I also prefer pinkish rubies and that little baby has life to her whether she's natural or not!
