The sack of gold was easily worth three points of plunder, with all the gold and gems in it, once they're finished appraising it. The large gemstone, on the other hand... if it were really made of solid ruby, the watermelon-sized stone would be worth a fortune, likely in the hundreds of thousands of gold. Even if it's only a layer of gemstone, it's still likely worth tens of thousands. Though, something seems... odd, about it.<br/><br/>(Know: Arcana, DC 21, upon inspection, will reveal that it's actually a red dragon egg. And one close to hatching, likely within a week or so.)
