Eu citzen, Streak is white and when i turn the rock this green blue coating has a shine to it. When looking at it through a loop the coating has needle points all over it that shine. Has green and blue needle points in it shining and reflecting back.Feels like sandpaper to the touch but its got a good hold on this crystal Eu.The crystal rock that is showing has a blue tint to it but when held against a light the the light shows all the way through it and it is white then except it does not shine through the coating. Thanks.
