This stunning large Cantera opal from Mexico features a brilliant window of bright electric green fire across the face, with even color visible on the back—giving it dimension and life from every angle.

Set in its beautiful natural matrix, Cantera opal is considered one of the most unique opals in the world, rivaled only by Boulder opal for its distinctive character and contrast. The intensity of the green fire against the matrix makes this piece truly stand out.

A bold, eye-catching stone that will not disappoint when seen in person. Perfect for a standout jewelry creation or collector’s display piece.

We are currently working with Opal Auctions to resolve this feature. In the meantime, if you purchase multiple opals from different auctions, we will create a single, consolidated invoice via PayPal. Please notify us when you are ready to make the payment, and we will send the invoice to your email. Kindly ensure that all auction winnings are paid within 24 hours. If you are participating in multiple auctions, we offer a 7-day window for payment after the final auction ends.

We would like to gently remind everyone that the opals we offer are of exceptional quality and, as such, represent a significant investment. Each piece is a result of careful selection, skilled craftsmanship, and the dedication required to bring it to you.

Our no-reserve auctions are designed to make these beautiful gems accessible to a broader audience. We kindly ask that all participants respect the value and effort behind each auction.

Should we find that auction participation diminishes, we may shift to direct sales and phase out the no-reserve format.

We sincerely appreciate your understanding and support. Your involvement helps us continue this passion for fine opals.

Thank you!

Thank you for your understanding!
