Welcome to the Tanzanite Blue Owners Club
Congratulations also on a beautiful car!
With regards to the colour it is very much a different colour depending on the mood of the day. If the sun shines it looks absolutely stunning and you can stare at the speckles in the paint for ages. On a wet day the car is darker and has a depth to the colour that seems to give the car a bit more of a gravitas.
EBII is nice but I don't think it has the same appeal, it may have the all weather wow factor but in all those weathers it is the same colour and there isn't the same depth. I much prefer the multiple personalities Tanzanite offers. I may be a bit biased though
