First off, you MUST set the seed to large biomes to get this feature. You spawn in a plains biome right next to these two MASSIVE twin ravines that are stacked on top of each other (yes it is two ravines). One of which contains an exposed mineshaft. They are connected to tons of caverns and I flew around for less than 2 minutes before I found exposed diamonds. If you want adventure right from the start, then this seed is excellent.
Confirmed. Village a ways off (X -267 Z 42, no blacksmith) from the double ravine (X -215 Z 203). That is a NICE double ravine, directly above a lava lake, my favorite kind of ravine.
I dug down in front of the stairs inside the church of the village. Five blocks down, ravine.
