DESCRIPTION
A classic prong-set clear gem, this 3mm solitaire is the perfect flat back stud! It's great as a minimal look in a first piercing, but small enough to work in seconds, thirds, and cartilage piercings.
This listing is for a single ASTM F136 implant grade titanium push-pin flat back stud. Note that the edges of the front piece can be a little sharp, due to the intricate detailing around the edges.
Measurements:
- 18 GA (1mm)
- Post is 1/4 inch (6mm) in length, with a 4mm disc on back.
- Approx. size of front piece is 3mm.
- Refer to listing images to get an idea of the size of the stud on-ear. Check your own ear measurement before ordering

Frequently Asked Question
We’ve got answers to all your Cords Club questions, from shipping to stacking.
I'm new to flat backs. What is the most important thing for me to know?
The first thing you'll want to learn is how to keep your Flat Backs nice and secure. Just like you'd tie your running shoes to make sure they stay on your feet for a run, you'll need to adjust your Flat Backs to keep them in place, too!
But don't worry! It's an easy peasy process, and we'll help you through the learning curve. <3
Here are a few resources to get you started:
* Review the Flat Back tips and tricks info guide included with your order
* Check out this helpful playlist of how-to videos
* Connect with our customer service team for personalized help
What size are the flat back earrings?
Cords Club's Flat Backs are 18 gauge and come with a 6mm long Flat Back post.
A 6mm post is a great length for most people, so we d recommend starting there!
We do also have a range of other sizes available and sold separately. If you have questions about sizing, we'd love to help!
Are your flat backs sold individually? Or in pairs?
Our Flat Backs are sold individually, so make sure to add 2 to your cart if you'd like a pair!
Do I need to buy the flat back applicator, too?
Our Flat Back Applicator is a great tool but it's not necessary! The Flat Back Applicator is designed to help make the process of changing your flat backs faster and easier, but you can definitely change your earrings without one. The choice is totally up to you!

I just invested in multiple flat back earrings from cords club within the past month and this one fell out without my noticing. I like the concept but for the price I need them to stay in and not fall apart so quickly.
CCCords Club1 month agoHi Meghann!
Thanks so much for the 3-star review of the Solitaire 3mm Flat Back Stud! We're sorry to hear that one of your studs fell out without you noticing—that's definitely not the secure, reliable wear experience we want you to have, especially when you've invested in multiple pieces from us! 😔
We totally understand how frustrating that must be. Push-pin flat backs work a little differently than regular earrings, and there's a good chance this happened because of a tension issue with the backing that wasn't resolved with the adjustment.
Please reach out to us at hello@cordsclub.com so we can sort this out.

Perfect size but three sets all three absolutely love. I have such sensitive ears. I have been wearing these over a month now not one issue could not recommend these anymore. Love love love.
CCCords Club1 month agoHi Ashlyn!
The Solitaire 3mm Flat Back Stud proves that sometimes the perfect middle ground is exactly where magic happens! ✨ We're so glad 😀 they've been gentle on your sensitive ears and have become your go-to pieces for over a month now — that's the kind of love story we live for! Thank you for the glowing recommendation and for the amazing 5‑star rating!
😘~ Elvie with Cords Club
- Carrie C.Verified Buyer1 month agoRated 5 out of 5 starsPerfect size
I originally bought the 5mm but realized they were too big for my double conch. Live the size of these and the sparkle!
CCCords Club1 month agoHi Carrie!
We're so happy you found your perfect fit! It's amazing how much difference the right size makes—the 3mm really is ideal for double conch placements, and we love that you're getting all that gorgeous sparkle without it feeling too big. Sometimes it takes a little trial and error to find that sweet spot, but it sounds like you nailed it! ✨
😘~ Elvie with Cords Club
