ReffeerSolid 925 Sterling Silver Tassel Chain Drop Dangle Small Hoop Earrings Huggie for Women Teen

Q: can you use it for your nose?

I'd say this is too big for the nose (assuming you want to wear it as a bull ring). The chain dangle would hit your lip and you likely wouldn't be able to get the clasp closed very easily. Also, the clasp isn't very secure and they break easily.

Q: Is sterling silver 925 with 14k gold?

Yes, friend, the earrings are made of 925 sterling silver, plated with 14 gold gold.

Q: what is the gauge size?

I’d say that the gauge size is about a 16g but it might be a little less at around an 18g

Q: Are these hypoallergenic? Thanks!

If you have any reaction to previous metal like skin gets red, itchy or anything I wouldn't get them. Stainless steel is more suitable for hypoallergenic reasons. I haven't had any issues with these and I wear them for days at a time. Hope this helps a little.
