Diamond Flat Back Earrings
MADAJ's stud collection is the backbone of the brand's piercing range. These are the pieces that work across almost every ear placement (lobe, helix, forward helix, conch, tragus) and nose piercings, making them the most versatile category in the collection. What unifies them is the flat-back post design: a smooth disc backing that sits flush against the skin, paired with a secure screw-on closure that will not loosen or fall off.
Every diamond flat back earring in this collection is set with natural G-VS quality diamonds in solid 18k gold. Designs span from single solitaire stones to multi-diamond motifs including lotus flowers, stars, moons, lightning bolts, and abstract cluster arrangements.
Why Diamond Studs Are the Standard in Piercing Jewelry
If you have ever slept in a traditional earring and woken up with the back digging into your neck, you understand the problem that flat back earrings solve. The disc back distributes pressure evenly, and because it sits inside the piercing channel rather than protruding behind it, there is nothing to catch on hair, pillows, or headphones. For piercings worn 24/7, this is not a small detail.
MADAJ studs use internally threaded posts, which means the screw threads are inside the post rather than on the outside. This makes insertion smoother and prevents the threads from scratching the piercing channel, an important consideration for cartilage piercings that are more sensitive to irritation.
Diamond Stud Sizing, Customization, and Fit
Stud post lengths are available in 5mm, 6.5mm, and 8mm to accommodate different tissue thicknesses. A thinner lobe might suit 6.5mm, while a thicker conch or helix area may need 8mm. Each product page includes a sizing guide, and all posts use a standard 1.2mm gauge.
Every stud is available in three 18k gold colors (white, yellow, rose) and is handcrafted to order. Each piece ships with a certificate of authenticity, free insured delivery via DHL Express, and a 30-day return policy.
