Shipping, Returns & Our Guarantee

How buying from us works

Browse the catalogue — every stone shows its tag price. When you find a stone you want, enquire or reserve it and we confirm availability and issue an invoice. No payment happens on this website and we never ask for, nor store, card details online. Goods are dispatched once the invoice is settled.

Shipping

Returns — 7-day inspection

Our authenticity guarantee

We are miners, not resellers. Every stone we sell is natural Australian opal, and solid unless expressly described otherwise — never synthetic, never dyed or treated.

Every stone carries its own certificate with a QR code that links back to this site, so what you hold can always be verified against what we published. If a stone ever proves to be other than as described, we will refund it in full, including all shipping.

Questions

Email sales@christianos.com.au or call +61 467 553 886 before you buy — we would rather answer twenty questions than have one disappointed buyer.
