The fusion of obsidian and titanium metal endows these studs with a dual aesthetic—combining natural subtlety with modern minimalism. Each obsidian stone is carefully selected and meticulously polished to ensure uniform color, then set within a polished titanium base; the result is a look that is understated from a distance yet rich in detail up close. The earring backs feature a classic butterfly-spring mechanism, allowing for easy fastening with a gentle push and equally effortless removal. The butterfly back fits snugly against the post, ensuring the earring remains secure during daily activities—such as bending over, sleeping on your side, or changing clothes—without exerting excessive pressure on the earlobe. To accommodate various styling preferences, we offer three sizes: 3mm (Mini): Small and delicate—ideal for secondary piercings or those who prefer a subtle look; 4mm (Medium): A versatile size—perfect for wearing alone or pairing with other earrings; 5mm (Large): A bolder presence—suitable as the primary earring for the earlobe. Titanium itself is naturally hypoallergenic; furthermore, the posts undergo multiple polishing stages to ensure a smooth, burr-free surface. Combined with the rounded contours of the butterfly backs, these earrings remain comfortable behind the ear even after prolonged wear.
