This is the perfect nose ring! After having my nose pierced for 25 years, every nose ring I have used fell out constantly, usually I would feel and catch it but not always (especially in my sleep!) That amounts to a lot of lost diamonds! Im very impressed with the 18g post and the 2mm diamond! Most of all because it stays in place and doesnt fall out!  I love the gorgeous sparkle the diamond omits in any light... the rose gold is beautiful, very well made and strong!  I highly recommend! (I would buy a back-up but I don't think Im losing this one for a LONG TIME!) JULY 2018 UPDATE Im still in love with this nose ring, I haven't lost it yet... although Ive learned that I seriously need to take a week or two off in between wear, after a week or so of wear it will start wanting to fall out... In washing my face Ive accidentally knocked it loose luckily catching it before going down the drain. Im still impressed by the gauge and stone!! I think my lesson is that old piercings stretch over time, if you wear any post w/o a back 24/7 its going to come loose, maybe a cork screw style would stay in day and night but I suggest just taking it out at night for everyday wear
