Undervalued gem Boulder opal

Must view this gem boulder opal as i think its under priced
any opal with veins of fore we have always sold well in USA
n this one weighs 10.7 carats and set in white gold
Gold setting $180 to make so opal cost only $715 or $70 per carat
where can u find gem boulder for $70 per carat???????
