Help Request: setting small 3mm heart stones

Hi, all. This is my first post to this group and was referred here by
another silversmith. I have a number of 3mm topaz and want to either
make silver setting for them or, failing that, find a source for
silver heads. I do lapidary and silver work, but my setting have been
limited to bezels on cabochons. I also buy heads from Tripp's and Rio
and then incorporate faceted stones into the stuff I do. I recently
purchased a parcel of topaz and part of it was a bunch of 3mm hearts.
They wouold be great as accents to larger stones, but I have to find a
way to set them. Making a handmade prong setting that small would be
tough I think and before I attempt it, I thought I would seek help. I
haven't worked with PMC, but was considering it using a torch. I
doubt that topaz would hold up while firing like corundum does(does
it?) Anyway, I will definitely appreciate any help on this.
Otherwise, I just have a bunch of loose stones with nowhere to go )
