Koios brings elongated gemstone movement into fine piercing jewelry with a slim four-stone layout and polished 18K gold finish. The graduated faceted gems create a refined line of sparkle, giving this piece a balanced, directional look that feels elegant without becoming too heavy.
Crafted by Industrial Strength in solid 18K yellow gold, this decorative end measures 8.94mm x 3.89mm x 2.1mm. The design features four faceted gems: two 1mm stones, one 1.5mm stone, and one 2mm stone, creating a soft progression of brightness across the elongated form.
Compatible with 18g/16g, 14g/12g, and threadless systems, Koios works beautifully across professional piercing setups. It fits naturally within the Threadless Ends, Minimalist collection, and Statement collection, while its slim gemstone profile is especially suitable for Helix Piercings, Flat Piercings, and Conch Jewelry.
