Most of their polished pearls use an 800 grit US surface (light grey nylon pad) under a heavy duty load of the Factory Finish polish.
If you've used a maroon nylon pad on it (approx. 320 grit US), I'd suggest using the maroon nylon ad and redo the whole ball, smoothly. Then use a green nylon pad on the whole ball, bringing it to approx 600 grit US. Then use a light grey pad on it to bring it to 800 grit US. Then use their Factory Finish polish to put a high gloss shine on it.
Since everyone's hand application is a little different, you may need either a rougher surface under the polish (green pad/600 grit US) or a finer, smoother finish under the polish (2000 grit Abralon = approx 1000 grit US) to get the same reaction as you did out of the box.
All the above assumes you're using a spinner. If not, take it to a pro shop and ask them to do it.
