Nice gauge size, got the 18 ,normally get 20 gauge. The diamond is small. The price is good for this jewelry. It was on sale and plus I also got a discount. I have to make sure I buy the bigger size gem. I have an earring I use for my nose piercing as well and realized that 2 mm is pretty small. 3 mm is probably a good size if you want it to be noticeable. Maybe just used to the bigger size when I switched to this. It is still a nice nose jewelry.
