Vintage 10k gold blue sapphire and diamond ring # all precious stones/ natural

10 k gold. Used good condition. This stone is not man made it is a natural true blue sapphire and if you look at the inclusions on the stone you will be able to tell. I think that this sapphire probably was mined from somewhere away bc of the colors. I tried to show you under light. There is a beautiful flash. So the dif color you see in it is just the flash from the narural inclusions I’m guessing. The stone is not scratched and these photos trust me we’re not enhanced if that was the case it wouldn’t have taken me over an hour to get decent photos. I read that sapphires weight as in size is dif then a diamond . By me measuring it last night I’m guessing 1ct approx on stone. Maybe bc it’s a decent size for the ring being a size 4 weighing 1.8 grams. This can be sized up or down . There is 6 natural diamonds in all.atleast. . So there is a good amount of beautiful precious stones.. All tested and verified. Offers are welcome. It will be cross listed. On size of sapphire approx. guess. Plz view photos for best description. Seems like a big stone on a tiny size 4 ring. Stamped . 10 k with lettering of company .used good condition. This ring is pictured under light for best view. Free gift w purchase ( mystery) always package my jewelry w/ care. Offers welcome
