Ultrasonic drilling service.

YowahOpals offers FREE DRILLING on any opal purchased from YowahOpals and YowahRough on Opal Auctions.
We can drill holes from 0.5mm to 3.00mm in Diameter.
The holes can be drilled through the side - or through the face of the opal - or can be top drilled - or any other drilling configuration that you can think of.
Ultrasonic drilling is the safest way to drill Gemstones. It is a gentle Ultrasonic vibration and carbide grit that softly drills through the stone effectively and efficiently .
