Product｜Natural Unheated Bright Velvet Blue Sapphire Quality｜<<Unheated>> A very beautiful sapphire from Sri Lanka. From the appearance, we can almost call it "cornflower blue sapphire", but because many certification centers still have controversy over the term "cornflower blue", and each seller and mine has different definitions of the term "cornflower blue", each company can call it "cornflower blue", but some laboratories believe that this has reached the color of cornflower blue, while others believe that it needs to be more saturated. After all, "cornflower blue sapphire" is just an industry benchmark and a commercial name. If it is not used as an investment target, it is meaningless to argue about what is cornflower blue. The outstanding thing about this blue is that this blue is a bit unrealistic, like a cartoon blue. The high saturation gives people a dual feeling of calmness and warmth. The author saw in the video that the presentation of this sapphire under natural light has a large proportion of Fu that feels very blue velvet, so it is determined that it can be called cornflower blue sapphire.
