Emerald setting advice

Hi! My husband gave me an 8x6mm emerald cut emerald for Valentine’s Day. I am working with a jeweler to have it set in a pendant. I need some advice on the options they provided. I want it bezel set east west orientation.

The first option is a bezel set with double bale either fixed or letting the chain slide through the bales. The second option is bezel set with a slide through and therefore a thicker bezel.

They also say with either option it will be on a 1mm 14-16 inch diamond cut 14ky chain.

What do you all think? I’m having trouble picturing it.
