[Rubinam]

What do you think is the best melee size for halo with centre stone around 5.75 mm(0.75 carat round diamond).I don't want a chunkier halo.I chose the below setting for my ring.Which melee size makes the center stone look better 0.01 or 0.015?Can i chose 0.01 for halo and 0.015 for the band.Will the band with bigger melee size is going to overpower the halo ?Please pour in your suggestions.Which setting is used in general for making the halo sparkle more ?

Can anyone guess the size of melee in the below setting?
