ok, so i spent a LONG time this afternoon trying to get good comparison pictures. i even attempted to take some outside, in the sunlight, but i just wasn't havin' much luck getting the hues of these blues right!

but i had a pair of 5mm Tanzanite Asschers, 8.5mm cushion medium blue, 8mm OMC blue sapphire coloured CZ - all from ChrisCZ - and a 7mm BTD Avarra Kashmir.
















sorry about the fingerprint smudges... the lighter one on the left is the OMC CZ and the one on the right is the ChrisCZ lab sapphire
