Recruit bunch of people with pioneer skill, and it will raise the heart stone lv pretty fast by just passing time.

Level seems to be tied more to the number of items shipped rather than their value. You can raise it just by shipping thousands of Stone Pebbles which sell for 0 (Stonecutter+Junk Stone=20x pebble). Anything else you end up with thousands of, throw it in the box.

I think it's actually a combination of both quantity and value, similar to how the compost works with weight. Low value items like the mentioned pebbles still have a minimum XP per item. High value items are worth more, but with very significant diminishing returns.

As Sotanaht said if you hold onto all the pebbles you get from mining they do indeed accelerate the hearthstone leveling too. You just don't get any money for pebbles.
