discussion about my colour change stone pls

[Tariq wali]

for a long period i thought this is a lab created stone ,so i did not give more attention on it , after some time i came to know that it is a color change, and after some further examination with my loop I found some positive symptoms as per my knowledge though I'm not a gemologist (I may be wrong) till today i did not consult to any gemologist , these all photographs i am posting is taken from my camera , what i am seeing in it , so experts of this forum please help me what they estimate about its natural origin, i have some experience with our local gemologist of my area , so i have a plan to visit bangkok for further examination ,it will be depend IF IF IF EXPERTS OF THIS FORUM WILL PUSH ME TO CHECK IT IN A GEM LAB . I know photographs cant help to identify but i hope may be they will provide some good suggestion to save my money for useless expenditures .

while i can see intersecting silk inclusion in it and i tried it to capture, but about the large size of that stone me .

i am unable to upload pictures here,facing error to upload, can anyone help me to upload from my pinterest link ?

There are synthetic colour change sapphires. Can't tell for sure but those could be synthetic growth lines. Just bring it with you to Bangkok to get it checked out.

there are surface abrasions along the facet junctions
there is at least one feather or chip
I do not see any silk, per se

abraded junctions have no identification value, any material can get them
the feather could be from internal stresses whether natural or not, or from physical trauma, again providing no clue to origin.
I do not think the straight lines are silk, but only artifacts of poorly polished facets, because they do not intersect at the angles that rutile silk do, and they are on the surface.
