“Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their  glossy iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described.  The larger and more spectacularly colored jewel beetles are highly prized by insect collectors.  The elytra of some species have been traditionally used in beetlewing jewelry and decoration in certain Aisan countries.” (quote from Wikipedia)  Below are about 36 species and a couple of videos.
