no input from anybody where’s all the saphhire lovers what is this beautiful blue stoner and ?
Have you done a specific gravity test and a refraction test? That pair of tests would speak volumes more about the material of the stone than trying to rutile inclusions in the stone under microscopes. There is a whole class of gemstones that might have similar inclusions, but only the specific gravity and refraction index can pinpoint that it's a sapphire.
If it really tests out by a professional as natural, untreated sapphire, and it weighs 2.5 grams, then that is equivalent to 2.5g x 5 ct/g = 12 ct. Faceting it by reaching out to a professional cutter (such as Precision Gem) might reduce the carat weight somewhat, but even if it's cut down to 10 ct, the additional sparkle and beauty would make it fetch $100k.
I am highly skeptical that it is untreated natural sapphire from Victorian times. Even in Victorian times jewelers could facet gemstones a lot better than your picture. I think it's more likely that what you have is a synthetic stone with either wear close to the surface of the stone or inclusions introduced in the manufacturing process. The shape of the stone looks similar to me to rings coming out from the former USSR, and I think the bored Soviet scientists were excellent producers (and probably inventors) of many synthetic gemstones, including diamonds.
