What is the "Wynning" Flat Back and why is it better?
The "Wynning" Flat Back is our signature design engineered for maximum comfort. Unlike traditional earrings with sharp posts and bulky butterfly backs, our flat back sits smooth against the skin. This makes them the perfect choice for sleeping, wearing headphones, or active lifestyles, as there is nothing to poke or snag.
Are these diamonds ethically sourced?
Yes. We use high-quality, ethically sourced lab-grown diamonds (F-G color, SI1 clarity). Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds but offer a more sustainable and transparent choice for the eco-conscious collector.
Can I wear these in my helix, tragus, or conch piercing?
Absolutely. Because of the flat-back design and the variety of stone sizes (1.5mm to 3mm), these studs are the gold standard for cartilage piercings. They provide a low-profile, high-sparkle look that is both secure and hypoallergenic.
How do I ensure the threadless (push-pin) top stays secure?
Security comes from tension. To "lock" your earring, insert the pin halfway into the post, give it a very slight bend, and push it the rest of the way in. The more you bend the pin, the tighter the fit will be.
Your earring includes an 18G titanium labret post. Upgrade to a matching 14k solid gold labret for an all-gold finish.
