Australian opals imported to Poland, then cut by hand and polished. I work low-volume and mostly lower grade rough - when you want a neat little opal but your budget is not ready for that harlequin black opal with high brightness. No photoshop, no artificial enhancement.
I work all my stones by hand, on a variety of surfaces that include knife sharpeners, sandpaper, and letter.
Many of my opals can be seen as they were in the rough! I also run a Youtube channel where a lot of the opals I have were shown, from their rough state to now.
