If the WF diamond is eyeclean I personally would choose that one. Also if you wanted to upgrade in future you could do so with this diamond.

The WF stone you have picked out is the exact same weight as mine

I''d go for the WF. Having the option to upgrade is extremely important, IMO, and for that reason I wouldn''t pick a diamond from BN and the JA policy is the diamond must be 2X the original amount (I''m pretty sure WF doesn''t have this stipulation), which is less favorable.
