A true Spencer story

Five decades in the open pit, behind the wheel, and across the counter.

The Sudweeks family has open-pit mined, cut, set, and sold opal for more than 50 years. Hot Rock Gems brings that experience into every selection: honest descriptions, personal help, and stones chosen by people who know the opal firsthand and prioritize quality above all else.
