Sapphire diffused ?

0 votes

Hello Everyone,

as an !absolute! newby (to both, the forum and gemstones) let me ask a question, I've come across a diamond cut .6ct sapphire which looks really nice. To find out anything about it I looked at it with a loupe and dropped it into a solution with a refractive index of ~1.5 (no access to diiodedmethaen) and noticed an inhomogeneous color distribution. Is this on its own an evidence of diffusion treatment?
