Hi everyone!! I am brand new to my tumbler and would like some direction on how to polish my Oregon sunstones without rounding them if that's possible. I love the rough fractal look but I want to bring out more clarity. Thank you for your time and help.

Welcome from Delaware. Tumbling with minimal rounding is best accomplished by a Vibratory tumbler.

Welcome to the forum from Arizona. I have tumbled Oregon Sunstones but mine came out rounded which I didn't mind.

You can get less rounding by either skipping stage 1 (coarse) or tumbling stage 1 & 2 for a shorter time.

I've tumbled lots of sunstones in sand just to clean it up, it brightens up somewhat. That might give you the look you want.

Welcome from Delaware. Tumbling with minimal rounding is best accomplished by a Rotary tumbler. Did you mean, vibratory? Yes I said Rotary tumbler. but meant Vib tumbler which is faster but it will not round the rock as wiil a rotary tumbler. rocktumbler.com/rotary.shtmlTypes of rock tumblers There are two different types of rock tumblers – rotary and vibratory. Rotary tumblers are much more common and best for beginners. When most people picture a rock tumbler, they’re thinking of a rotary. This is the type of tumbler that will knock off the edges, shape, and smooth out rough rocks during the coarse grind stage. Rocks tumbled in a rotary tumbler will change shape and become rounded. Vibratory tumblers are less common with beginners and are typically used for fine polishing rocks you’ve already shaped. A vibratory tumbler will not shape your rocks like a rotary tumbler. If you just want to polish your rocks and maintain the same shape and angles, then a vibratory tumbler may be for you. The main advantage of a vibratory tumbler is that it dramatically speeds up the tumbling process for stages AFTER your rocks have been shaped (i.e., medium grind, fine grind, and polish). So while each of the four stages in a rotary tumbler can take a week on average, stages 2-4 can all be done in only one week. An ideal setup would be to buy both a rotary and vibratory tumbler.
