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 gemstones natural? Yes. we use premium Natural Blue Sapphires, Emeralds, and Pink Sapphires. Because these are earth-mined stones, each gem will have its own unique personality and depth of color, making your specific piece one-of-a-kind.
What are the benefits of the Princess Cut? The Princess cut is a modern square shape designed for maximum brilliance. Its symmetrical silhouette makes it incredibly versatile, fitting beautifully in centered placements like the tragus or conch, as well as in a structured lobe stack.
How do I secure the threadless push-pin top? Our "Wynning" system is secured by tension. Simply insert the pin of the 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 that is much more reliable for 24/7 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.
