Were it larger, and you wanted to keep it, id say leave as is, or at most as Lord said. Future sale, you can let the buyer decide.
If your finding gold for $$ then smash it and take the gold.
Don't know if your just a year or two in, or longer (going off site member info.), but i tend to be sentimental about very few pieces these days.
Nice to keep the 'milestone' bits (1st, biggest, looks etc...), beyond that, unless you have a specific buyer in mind, most gold buyers won't pay for the rock...and occasionally, drop the price if encrusted with ore.
Question is...what is the end-game for your gold...keepsakes?..or profits?
Within the answer you will find your course of action...
