See - this looked like denim-y kind of colour when I was at the torch (must have been the glasses) - but it is clearly a sapphire blue. CiM says that this has been engineered to be the same colour as sapphire, without the colour shift that some people reported having.
Anyway you slice it - it is a stunning shade of blue.
Two self-coloured spacers and one over white.
Here - same beads - backlit.
And backlit with a dark background.
Hmmm - looks like I put them in the kiln too hot and they unbalanced a little. Oh well.
Super pretty blue, dark enough to have impact, without being so dark you have to get crazy to see the colour.
