About
HIJA by Quilla Diaz Athanasiadis
HIJA rings and necklaces are designed to be cherished for a lifetime.
Quilla is drawn to creating bold yet minimalist jewellery—pieces that are both timeless and iconic. Each design is handmade in her Melbourne studio from 100% recycled sterling silver and cast by industry-trusted metal casters. Using the lost wax casting process, every piece is made to order, ensuring a zero-waste production.
HIJA (i-ha) – A Spanish word meaning ‘daughter’
HIJA is a reflection of Quilla’s identity. With a European mother and South American father, her cultural background plays a strong role in shaping her vision. Growing up in Australia, she was deeply influenced by ’90s pop culture and streetwear, elements that naturally weave into her designs.
Through jewellery, she has created a world that embodies her heritage, personal style, and core values—confidence, women’s empowerment, and individuality.
