The Princess Cut Gemstone Flat Back Earrings are the ultimate solution for a high-style, low-maintenance ear curation. Handcrafted in solid 14K white gold, these studs feature a perfectly square-cut natural gemstone set in a refined four-prong setting. Whether you choose the mystical, iridescent glow of Moonstone or the deep, authoritative blue of Blue Sapphire, these 2.5mm studs offer a sharp, modern silhouette that sits perfectly flush against the ear.
Each 14k gold flat top includes a 5 mm hypoallergenic titanium labret, suitable for most healed piercings. A 14k gold labret is available separately.

Does this earring come with the back post? No, this listing is for the decorative gemstone top only. Because everyone’s ear anatomy is unique, our Wynning Labret/Posts are sold separately. This allows you to choose the exact length (4.5mm to 7.5mm) required for a perfect, custom fit in your specific piercing.
Are these safe for sensitive ears? Yes. We use recycled, solid 14K white gold that is 100% nickel-free, lead-free, and cadmium-free. This high-purity metal is the safest choice for those with sensitive skin or metal allergies, especially in cartilage piercings.
What is the difference between Moonstone and Blue Sapphire?
Moonstone: Known for its "adularescence," it reflects a soft, dreamy blue light from within.
Blue Sapphire: A classic precious gem known for its incredible durability and deep, regal blue saturation.
How do I secure the threadless push-pin top? Security is achieved through tension. Simply insert the pin of the gemstone top about halfway into your labret post, give the pin a very slight bend, and push it in completely. This creates a secure friction lock far more reliable for permanent wear than traditional screw-on jewelry.
Your earring includes an 18G titanium labret post. Upgrade to a matching 14k solid gold labret for an all-gold finish.
