Seed Code: 7511399987291858775
I found this nice seed right after I updated my game and started a new random world.
The chests in the locations mentioned below offers 7 diamonds,
X: -172 / Y: 71 / Z: 270
There is a desert village right next to the spawn. It's rather small but a pyramid is right beside.
There are two larger villages at 36/71/101 (next to the floating mountain) and a bit more away from spawn at-970/71/-506.
X: -837 / Y: 65 / Z: -170
I found two pyramids so far, one right next to the spawn at -181/65/186 and this second one. Inside, you could find 7 diamonds, 3 emeralds and 15 gold in the chests.
X: -792 / Y: 83 / Z: -249
After searching for a while, I found this exposed temple. The entrance is set right into the mountain, so you have to find an other way in. The chest offers you 3 emeralds and 9 gold.
X: -982 / Y: 65 / Z: -173
I can not count the ravines I've found on this map, but the most impressive one for me was this double ravine. Also, there is a ravine near spawn at -100/65/-4 and a nice looking underwater ravine at -637/61/723. (Small hint: a stronghold is near this underwater ravine)
