Opals are impossible to represent accurately with digital stills, be wary of any seller unwilling to offer a 100% purchase price money-back return policy!

Win the auction, and if you aren't satisfied return the unaltered stone within 14 days of receiving it, for a no-hassles refund of your purchase price. I will combine multiple wins for the single postage charge; I require payment within 7 days of auction end, after 7 days without payment I reserve the right to terminate the sale and offer this stone to someone else.
