DESCRIPTION
One little stud, so many ways to wear it! Our Birthstone Flat Back Stud features a 3mm prong-set gem that's perfect for everyday wear. Wear as a birthstone, a favorite color, or something that just vibes with your ear stack—there's no wrong choice. This little flat back stud comes in gold or silver (titanium) and makes the cutest gift (yes, even for yourself).
This listing is for a single ASTM F136 implant grade titanium push-pin flat back stud. Note that the nature of prong settings can make them catch on hair or fibers.
Measurements:
- 18 GA (1mm)
- Post is 1/4 inch (6mm) in length, with a 4mm disc on back.
- Approx. diameter of gem 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
Materials: 18K PVD Gold Plated ASTM-F136 Titanium, ASTM-F136 Titanium, prong-set zirconia
Care: Water and tarnish proof with proper care. If exposed to salt water, chlorine, or lotions/perfumes, rinse off with cool-warm water and gently dry. When not wearing, store in a dry, cool place. Do not pull, twist, or tug on your jewelry.
CARE
Soak your studs in warm water with a few drops of dish soap for about 15 minutes. Gently clean with a soft cloth and store safely.

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?
Both! Grab a single if you’re mixing and matching, or a pair to save 10%
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!

- Ashley T.Verified Buyer3 weeks agoRated 4 out of 5 starsA little smaller than expected
Maybe I missed the description but this was a smaller stone than I expected. The color is very pretty though!
CCCords Club3 weeks agoHi Ashley,
Thank you so much for the feedback! We're glad to hear that you love the color of the Birthstone Flat Back Stud. We're sorry the stone size wasn't quite what you were expecting, and we really appreciate you sharing that with us. Every ear is different, and sizing preferences can definitely vary from person to person!

- Alicia S.Verified Buyer2 months agoRated 3 out of 5 starsMarch doesn't look very Aquamarine
Like a true pisces I'm going to cry about it. No one every gets the March birthstone right. These are just blue earrings, the stone isn't the right color.
CCCords Club2 months agoHi Alicia,
Thank you for sharing your feedback, and we're sorry to hear that the March Birthstone Flat Back Stud didn't capture the aquamarine color you were looking for. We understand how disappointing that must be, especially when birthstone accuracy is so important to you.
We really appreciate you letting us know about the color concerns. Your feedback is valuable to us as we think about how we can better serve our customers and their needs.
Please reach out to our customer support team at hello@cordsclub.com with your order details, and we'd love the opportunity to sort this out.
