Londoners (born and bred) - how do you pronounce Turquoise? Do you say Turk-wise, Turk-woyz, Turk-oyz or Turk-Wazz? Or none of the above?

I say 'turk-wise' though I've been told it's turq-woyz but that it's more common for Londoners to say 'turk-wise' as well. I've never heard it pronounced without the 'w' and absolutely never heard 'turk-wazz' but apparently some people say it that way.

I should probably do a poll. I just want an excuse to keep saying turk-wise.
