Thea | Seafoam Blue-Green Australian Semi-Black Opal Ring

Meet Thea – a jaw-dropping 9.25ct Australian semi-black opal ring handcrafted in 9ct yellow gold. Black opals are known for their striking play of colour against a dark background and Thea doesn’t disappoint. Radiating hues of seafoam blue, green and aqua, she is a portal into some other, watery world. One half dark and moody, and the other bright and shining, Thea captures the enigmatic beauty of a woman. All of our opals are natural solid opals, sustainably and ethically mined in Australia. Ring has been handcrafted to suit the individual opal, making it a truly unique and one-of-a-kind piece.

Ring comes in a beautiful sustainable timber gift box. The perfect box for the perfect ring, handcrafted inside and out. All rings include free custom sizing. If you are unsure of the recipient’s ring size, please choose the Default Size.
