Inclusions you might find in a Ruby 

Here we have a Natural unheated Ruby(origin is probably from Llakaka based on its inclusions-but I am not an expert on origin). When we observe this Ruby we find that the inclusions are undisturbed. We do find rutile also known as "silk", which is a natural inclusion commonly found in corundums(ruby and sapphire) and we find that there are nice euhedral shaped rutile inclusions. When we observed this ruby host, we find that the Rutile is undissolved and in a needle format that is intact and undisturbed. Because rutile has a lower melting point than the ruby, it would dissolve and be broken or be completely obliterated during the heating process. But because the rutile is so fine in the cloud I shoed in the video, along with the brownish red euhedral shaped rutile crystals that are undisturbed, we know that this is enough proof and evidence that this material is unheated.
