Hi Stephanie and welcome to the board. A trilobal Polyester in gold has the shimmer of a metallic. Glide or Superior Magnifico are both very shiny and have golds without being metallic.
Mettalics can be fragile and also do not glide smoothly through the fabric as RJLinkletter mentioned. I suspect you may get a lot of fraying and aggravation attempting to hand quilt with it, unless you used something like Wonderfil's Sizzle product which is an 8 wt and would easily hold up to the stress placed on thread for handquilting. But this thread will also probably give you some resistance when pulling through the sandwich. You would need to do a big stitch style as the thread is so heavy.
Here is a link to Wonderfil's on line store:

A little hint for this thread, get a washable glue stick like Elmer's washable glue sticks and run just the end of the thread through it and let it dry. Will make it much easier for you to thread your needle. When I use this product and others like it I do the glue stick on it as soon as I cut off a piece. That way by the time I am ready for a new length of thread, the end is already stiff and ready to get threaded onto a needle.
I have done some lovely sashiko style quilting with their Dazzle product which only has one strand of metallic mixed with rayon.
Now one note of caution, Rayon used to be notorious for not being colorfast and fading horribly. I don't know if that is still the case.
If you really want to play it safe but have that little shimmer or sparkle, go with Glide or Magnifico.
