About Us


Geologie Cosmetics is a brand inspired by the colours and hues of the rich Western Australian landscape. We create wearable colours from minimal, earthy tones to vibrant pigments that reflect the diverse beauty of country. Whether you use sleek, subtle colours that you can wear anywhere or glamourous shimmers and intense colour for that unique statement, Geologie Cosmetics offers polish that will elevate your look.

Geologie Cosmetics was born from frustration at the lack of local, independent make-up producers in Western Australia as was started by partners Eliza Stewart and Michael Osan, they have translated their love of the regions into cosmetic beauty for all to experience.



A geologist by trade, Eliza has spent her time travelling around the vast West Australian deserts, uncovering minerals and exploring the elements. Far from the city, immersed in the landscape, from the searing heat to the cool waters of the gorges and billabongs, she developed a deep love for the colours and tones of the landscape. This experience is coupled with lasting memories from  a rural childhood, sparking Eliza’s creativity and appreciation for the uniqueness of Western Australia.

With a keen interest in cosmetics, and a desire for make-up that is 100% cruelty-free, vegan and made with ethically sourced mica, Eliza decided to create a brand that would marry the sheer beauty and intensity of the Western Australian colours with an ethically produced product.

Geologie Cosmetics is for those who want a truly independent alternative to the big labels. Born from the earth, designed by a geologist, and made for those who appreciate the beauty of natural colour.
