For a playfully sophisticated alternative to our classic Tiny Crystal Studs, I designed the Crystal Trinity Studs. They're a cross between the Tiny Crystal Studs and our incredibly popular Tiny Trinity Studs.

Try teaming this earring with our Dewdrop Crystal Huggies or our Eternity Hoops. One earring, infinite possibilities.  Make it yours.

Our internally threaded flat back earring studs are made of solid implant grade titanium and are hypoallergenic and always nickel free.

We offer the flat back stud earrings as singles; if you'd like a pair, please order two.

Kept unscrewing :(

I loved this earring so much and thought it was so pretty/loved the flat back. Unfortunately it kept unscrewing and I would wake up with the earring laying in my bed, after about a week of wear and having to re tighten over and over again I lost one earring. Super disappointed because I think it’s so pretty and that flat back a great concept

Never shipped and took my money

Ordered a month and a half ago and haven’t received them. I keep getting emails asking how I like the products but I have yet to get them


Love the style


This ring is too big for stratus. I then tried it in my earlobe and the material agitated my skin.

Cute but a little hard to insert.

Love it once I got it in. I choose the smallest gauge for my healed cartilage piercing (done in 2000s) hoping it would be the same size as a typical eating stud post. It was too big to be easily inserted. After a few attempts I was able to get it done with my husbands help but it did hurt. I had to use antibiotic cream to heal it as it torn my ear slightly during the process.

The flat back is amazing and so so so much more comfortable for sleeping on my side.
