Neat to see Marlow! Shouldn't the small size help the leuco's to stay colorless, as there's less gem material for light to travel through? I've been looking for a pure leuco over 1ct., but I am beginning to believe by the time they get to that size they *all* show some tint...
I can't see any color in indirect daylight. Of course they are very small.
I have a 0,91 ct and 1,64 ct round which are colorless in incandescent light and faceup in daylight - from the side they have a tiny hint of
color ( yellow) - would be interesting to check them with a masterset.
If you expect an D-G like a diamond I would say it is impossible to find in a 1 ct size.
May stones are from eastafrica - they show a pink LW fluorescense - burmese material is included / never seen eyeclean stones.
Left the two larger round - at the end a Merelani Mint to compare...
Please look at the girdle - in the tip ( Merelani too ) you see a reflection of my hand
