PiercingJ2-5PCS 16G 3/8" (10MM) Stainless Steel Cubic Zirconia Gem(3MM) Internally Thread Curved Barbell Eyebrow Piercing Jewelry

Would is work for the snake eye piercing on the toung?

Can I use this for my smiley?

Would these work for a daith piercing?

Could these work for a rook piercing or would it look too large and ungainly? If anyone has used it for a rook, do you have any pictures of it? Thanks
