Geode

Geodes are a rare consumable dropped by Granite-themed enemies with a 5% chance. Geodes can be thrown with the attack button, causing them to drop 2 types of gems on impact with blocks. The amount of gems varies from 3 to 6

Tips

 * On average, the resulting contents of the geode are worth approximately 30 times more than its sell price.
 * This profit can be further increased by converting the contents to Stained Glass, worth about 10 times more than the gem ingredients and only requiring the addition of 10 sand per gem. However, a mass geode farm can produce thousands of gems per hour and this may not be worth the extra time it would take to harvest/create the insane amounts of sand required (see Sandgun for more details)
 * There may be a bias towards certain times of day for certain gems.
 * In a test of 114 geodes over the course of around 2 or three in game hours (7am to 10am) around 30% more diamonds and amber dropped.
 * Opening 650 geodes (This took one whole game day) revealed that in the morning (in game 4:30-11:30 am) diamonds and amber are more likely to drop
