I want to compare three corundum with same size, cutting and almost same weight.
A 0,55ct burmese Ruby - with a lot of rutil visible with 10-20 magnification - so maximum low heat treatment - maybe the best gem I have!
A 0,62 ct hot magenta Sapphire from Sri Lanka - heat or not - don't know!
A 0,61ct pink Sapphire from Sri Lanka - eyeclean - heat or not - don know!
From the side
A box with four magenta-hot pink Sapphire
